PDI Platform Developer I (SP23) Questions and Answers

 The issue is that the value of the account type field is not being displayed correctly on the Visualforce page. This can be resolved by adding a getter method for the actType attribute in the custom controller. A getter method is used to retrieve the value of a private variable, ensuring that it’s read-only and cannot be modified by external classes or pages, thus maintaining encapsulation and security. References: The need for getter methods and their usage can be referenced in Apex basics where encapsulation, getters, and setters are discussed: Apex Basics & Database

To support split shipments, a developer should add an Order_shipment_Group_c object and a master-detail field on Order_Line_c. The Order_shipment_Group_c object represents a group of order lines that share the same delivery method and destination address1. The master-detail field on Order_Line_c establishes a relationship between each order line and its corresponding order shipment group. This way, the shipping information can be stored in the Order_shipment_Group_c object instead of the Order_c object, and any number of order lines on a single order can be shipped to different locations.

 the current user has the permission to delete Account records, and false otherwise. This method is part of the Schema.DescribeSObjectResult class, which provides information about the metadata and permissions of an sObject type. The other options are incorrect because they either use invalid syntax or refer to the wrong object or variable. The accountRec variable is an instance of an Account record, not an sObject type, and it does not have an isDeletable() method. The Account sObject type does not have an isDeletable() method either, it is a property of the Schema.DescribeSObjectResult class. The AccountRec.ObjectType property returns the sObject type of the accountRec variable, which is Account, but it does not have an isDeletable() method either. References:

An Assignment Flow element is a logic element that allows you to set values in variables, collection variables, record variables, record collection variables, and global variables1. You can use an Assignment Flow element to assign the support representative name to the custom field on the Case object based on the case origin. This way, you can automate the case assignment process without writing any code or using any formula. A trigger, a formula field, and a validation rule are not the best solutions for this scenario, as they either require code, are not dynamic, or do not change the field value. References: 1: Flow Element: Assignment - Salesforce

To check the test coverage of active Process Builder and Flows deploying them in a Change Set, a developer can use SOQL and the Tooling API. The Tooling API provides the FlowTestCoverage object, which represents the test coverage for a flow or process by a given Apex method. The developer can use SOQL queries to retrieve the FlowTestCoverage records for the flows and processes that are included in the Change Set, and calculate the overall test coverage percentage. The developer can also use the Tooling API to create, update, or delete FlowTestCoverage records.

Option A is incorrect because the Flow properties page does not show the test coverage of the flow or process. Option B is incorrect because the code Coverage Setup page only shows the test coverage of Apex classes and triggers, not flows or processes. Option C is incorrect because the Apex testresult class only provides information about the test execution results, not the test coverage of flows or processes.

References: FlowTestCoverage | Tooling API | Salesforce Developers, How to Invoke Apex from Flows Using InvocableMethod Annotation, How can a developer check the test coverage of active process builder and flows deploying them in a changing set?

The Order Number field should be defined as an External ID and Unique field in Salesforce. This is because the Order Number is a unique identifier that comes from an external system and needs to be matched with the corresponding order records in Salesforce. An External ID field allows you to use the Order Number as a foreign key for data integration and upsert operations. A Unique field ensures that no two order records have the same Order Number in Salesforce. References:

Outbound messages are a way of sending information from Salesforce to external systems or applications in real-time when certain criteria or conditions are met. Outbound messages are sent as SOAP messages and can include fields from the record that triggered them. Outbound messages can be configured from Setup and do not require Apex code. Outbound messages can be associated with different automation tools in Salesforce, such as:

• Approval Process: This is a way of automating the approval of records based on predefined steps and actions. Approval processes can send outbound messages as part of the approval actions when the record meets the entry criteria and approval criteria.
• Workflow: This is a way of automating tasks and actions based on certain rules and criteria. Workflow rules can send outbound messages as part of the workflow actions when the record meets the rule criteria.
• Process Builder: This is a way of creating complex business processes and logic using a graphical interface. Process builder can send outbound messages as part of the process actions when the record meets the criteria node.

The Test.loadData < > method inserts test records from the specified static resource .csv file and for the specified sObject type, and returns a list of the inserted sObjects1. The file contains field names and values for the test records. The first line of the file must contain the field names and subsequent lines are the field values. To learn more about static resources, see “Defining Static Resources” in the Salesforce online help2. This method is useful for creating test data with specific field values without writing code. The other options are either incorrect or less efficient for this purpose. Anonymous Apex is a way to execute Apex code on demand in the Developer Console, but it is not a recommended way to create test data, as it is not part of the test class and may affect the org data3. SOQL is a query language that can retrieve data from the org, but it cannot create new data. Also, using SOQL to access existing data in a test class requires the @IsTest (SeeAllData=true) annotation, which is not a best practice, as it may cause test failures or unpredictable results4. Test.loadData does not support JSON files, only CSV files1. References:

 A standard list controller provides a list of records of a specific object type, such as Contact, and allows you to create Visualforce pages that can display or act on that data1. A standard list controller is suitable for this purpose, because it can easily query the contacts owned by the current user and display them in a table or list. A standard list controller also supports pagination, sorting, filtering, and mass actions2. A standard controller provides access to a single record of a specific object type, such as Account, and is not suitable for displaying a list of records1. A lightning controller is a JavaScript controller that handles user interactions and events in a Lightning web component, and is not related to Visualforce pages3. A custom controller is an Apex class that implements all the logic for a Visualforce page, and requires writing more code than using a standard list controller1. References:

• Using Standard List Controllers | Visualforce Developer Guide | Salesforce Developers
• Lightning Web Components Developer Guide | Salesforce Developers

To implement the Apex method that is executed when a recommendation is rejected, the developer should keep in mind the following factors:

• The method must use the @Future annotation because it performs a callout to an external system, which is not allowed in synchronous Apex. The @Future annotation marks a method as asynchronous, meaning that it runs in a separate thread and does not block the main execution1.
• The method must use the @invocableMethod annotation because it is invoked from a flow that is triggered by the Einstein Next Best Action component. The @invocableMethod annotation enables an Apex method to be called from a flow, process, or REST API2.
• The method must be defined as static because it is annotated with @Future and @invocableMethod. Both annotations require the method to be static, meaning that it belongs to the class and not to any instance of the class3.

A global picklist value set is a collection of values that can be shared across multiple picklist fields on different objects1. By using a global picklist value set, a developer can streamline the maintenance of the picklist and their values, as they only need to define the values once and reuse them across multiple fields. The global picklist value set also restricts the values to the ones defined in the value set, so that users cannot enter or select other values1.

Option B is incorrect, because creating the picklist on each object as a required field and selecting “Display values alphabetically, not in the order entered” does not streamline the maintenance of the picklist and their values, nor does it restrict the values to the ones mentioned above. The developer would still need to create and maintain the picklist values for each object separately, and the users could still enter or select other values that are not ‘High’, ‘Medium’, or ‘Low’.

Option C is incorrect, because creating the picklist on each object and selecting “Restrict picklist to the values defined in the value set” does not streamline the maintenance of the picklist and their values, either. The developer would still need to create and maintain the picklist values for each object separately, even if they use the same value set. The only benefit of this option is that it restricts the values to the ones defined in the value set.

Option D is incorrect, because creating the picklist on each object and adding a validation rule to ensure data integrity is not the best approach to streamline the maintenance of the picklist and their values, while also restricting the values to the ones mentioned above. The developer would need to write and maintain the validation rule for each object, which is more complex and error-prone than using a global picklist value set. The validation rule would also run after the user enters or selects a value, which is less user-friendly than preventing the user from entering or selecting an invalid value in the first place.

SOSL and SOQL are two different types of search languages in Salesforce. SOSL is a programmatic way of performing a text-based search against the search index, while SOQL is the equivalent of a SELECT SQL statement and searches the org database1. The developer should consider the following factors when deciding between SOQL and SOSL2:

• The number of records to be returned: SOSL can return up to 2,000 records from multiple objects, while SOQL can return up to 50,000 records from a single object or from multiple objects that are related to one another1.
• The speed of text searches: SOSL is generally faster than SOQL for text searches, especially if the search expression uses a CONTAINS term. SOSL can tokenize multiple terms within a field and build a search index from this, which makes SOSL searches more efficient and relevant1.
• The knowledge of the object or field: SOSL is useful when the developer does not know which object or field the data resides in, and wants to retrieve data for a specific term across multiple objects and fields. SOQL is useful when the developer knows which objects the data resides in, and wants to retrieve data from a single object or from multiple objects that are related to one another1.
• The type of data to be retrieved: SOSL supports text, email, and phone fields, and can retrieve data that is in Chinese, Japanese, Korean, or Thai. SOQL supports number, date, or checkbox fields, and can retrieve data from big objects1. References:
• Introduction to SOQL and SOSL | SOQL and SOSL Reference | Salesforce Developers

 The given anonymous block of code is trying to update over 10,000 Case records in a single transaction, which will exceed the governor limit. In Salesforce, there are specific limits to prevent operations from consuming excessive resources. One of these limits is the total number of records processed in a transaction. If this limit is exceeded, the transaction will fail.

References: The related information can be found under the “Apex Governor Limits” section in Salesforce documentation and learning materials on Trailhead.

I also noticed that you sent me an image along with your question. It seems to be a piece of code displayed on a screen with a light background. It’s an Anonymous Block of Apex code for Salesforce. The code snippet involves updating case records with the status “Working”. There’s an evident syntax error as it tries to retrieve 50,000 records which exceeds governor limits. A try/catch block is used to handle exceptions during the database update operation.

A polymorphic lookup field is a relationship field that can reference one of several different types of objects. For example, the Who relationship field of a Task can be a Contact or a Lead. The WhatId field on the standard Event object is another example of a polymorphic lookup field, as it can reference any object that allows activities, such as Account, Opportunity, Case, etc. To determine the type of the referenced object, you can use the What.Type field in a SOQL query. You can also use the TYPEOF clause to filter or select fields based on the object type. References:

• View the Apex Jobs page and query the AsyncApexJob object are two ways a developer can get the status of an enqueued job for a class that implements the Queueable interface. They are both methods to monitor and manage the asynchronous Apex jobs that are submitted to the Apex job queue12.
• View the Apex Jobs page is a user interface option that allows a developer to see the status and results of the asynchronous Apex jobs in the Setup menu of Salesforce. It can show the progress, completion, failure, or cancellation of the jobs, as well as the start time, end time, submitted by, and apex class name of the jobs12.
• Query the AsyncApexJob object is a programmatic option that allows a developer to retrieve the status and results of the asynchronous Apex jobs using SOQL. It can access the same fields and information as the Apex Jobs page, as well as additional fields such as JobType, ParentJobId, and ExtendedStatus12.
• View the Apex Status page and view the Apex Flex Queue are two other options, but they are not applicable for the Queueable interface. They are used for different types of asynchronous Apex jobs12.
• View the Apex Status page is an option that allows a developer to see the status and results of the batch Apex jobs and future methods in the Setup menu of Salesforce. It can show the number of batches or methods processed, failed, or remaining, as well as the start time, end time, submitted by, and apex class or method name of the jobs12.
• View the Apex Flex Queue is an option that allows a developer to see and reorder the pending batch Apex jobs that are waiting to be processed in the Setup menu of Salesforce. It can hold up to 100 batch Apex jobs that exceed the limit of 5 concurrent jobs. It can show the apex class name, submitted by, and submitted date of the jobs12.

 In Salesforce, the sharing rules are always enforced for the running user if not explicitly stated otherwise. The running user’s permissions and field-level security are always enforced, regardless of whether the class is defined with or without sharing. So in this case, since there is no explicit sharing declaration in the provided code snippet, it defaults to enforcing the sharing rules for the running user. References:

• Apex Developer Guide: Using the with sharing, without sharing, and inherited sharing Keywords
• Trailhead: Apex Sharing and Security

 By adding the @IsTest annotation above the class definition (line 01), it indicates that this class is a test class, and therefore, can only be used by other test classes. This ensures that the helper methods within are only accessible to unit tests, aligning with the best practices of encapsulation and modularity in Apex code. References: The related information can be found in the Apex Testing module on Trailhead ([Apex Testing](1(https://trailhead.salesforce.com/en/content/learn/modules/apex_testing%29%29.

• Scheduled Flow and Record-Triggered Flow are two automation tools that a developer can recommend to meet the business requirements of sending a follow-up email reminder 6 hours after the stage_c field is set to ‘Waiting on customer’. They are both bulk safe, meaning they can handle large volumes of records without hitting governor limits12.
• Scheduled Flow is an automation tool that allows you to run a flow at a specific time or on a recurring schedule. You can use it to query the Case object for records that have the stage_c field set to ‘Waiting on customer’ and then send an email reminder to the case owner or the customer3 .
• Record-Triggered Flow is an automation tool that allows you to run a flow when a record is created or updated. You can use it to create a scheduled path that executes 6 hours after the stage_c field is set to ‘Waiting on customer’ and then send an email reminder to the case owner or the customer .
• Einstein Next Best Action and Process Builder are two other automation tools, but they are not suitable for meeting the business requirements. They are not bulk safe, meaning they can hit governor limits when processing large volumes of records12.
• Einstein Next Best Action is an automation tool that allows you to provide intelligent and contextual recommendations to users based on business rules and predictive models. It is not designed to send email reminders based on field values .
• Process Builder is an automation tool that allows you to create a process that performs actions when certain criteria are met. It can send email alerts, but it does not support time-based actions for record update triggers. It also has lower limits for the number of email alerts and scheduled actions than flows .

A trace flag is a special setting in Salesforce that captures detailed information about the execution of Apex code1. It records various events, such as the execution of Apex methods, SOQL queries, and DML operations, and writes them to a log file1. Trace flags can be configured for three types of entities: Apex classes, Apex triggers, and users2. For Apex classes and triggers, trace flags override the default logging levels and enable logging for the specified class or trigger2. For users, trace flags enable logging for all the Apex code executed by that user2. Trace flags can be set up using the Developer Console, the Tooling API, or Setup2. Flows and Visualforce pages are not valid entities for trace flags, as they are not Apex code34. References: 1 TraceFlag | Tooling API | Salesforce Developers1, 2 Debug Log Levels - Salesforce2, 3 Flow | Tooling API | Salesforce Developers3, 4 Visualforce | Tooling API | Salesforce Developers4

A Paused Flow Interview is a flow instance that has been paused by a Wait element or a Pause element. A developer can find information about a Paused Flow Interview on the Paused Flow Interviews related list for a given record, if the flow is configured to store the record ID in the Interview Label field. This allows the developer to resume, delete, or view the details of the paused flow interview from the record page1. The other options are not valid ways to find information about a Paused Flow Interview in the Lightning UI.

The @InvocableMethod annotation is used to identify methods that can be run as invocable actions from a flow, a bot, or an NBA. There are some considerations when using this annotation in Apex, such as:

• A method using the @InvocableMethod annotation must define a return value, even if it is null. This is because the invocable action must return a value to the flow, bot, or NBA that invokes it.
• A method using the @InvocableMethod annotation can have only one input parameter, which can be a list of a primitive data type, a list of a specific sObject type, or a list of a generic sObject type. This is because the invocable action can accept only one input value from the flow, bot, or NBA that invokes it.
• A method using the @InvocableMethod annotation must be declared as static, because it is not associated with a specific instance of the class that defines it. Static methods can be invoked without creating an object of the class.
• A method using the @InvocableMethod annotation can be declared as either public or global, depending on the visibility of the invocable action. Public methods are visible within the same namespace, while global methods are visible across namespaces.
• Only one method using the @InvocableMethod annotation can be defined per Apex class, because each invocable action is associated with a single Apex class. Multiple invocable methods in the same class would cause ambiguity and confusion.

To make an Apex method available to a Lightning web component, the developer must follow these considerations1:

• The method must be annotated with the @AuraEnabled annotation, which enables client-side access to the method.
• The method must be either static or part of a global class, and it must be public or global.
• The method must specify the cacheable=true attribute if it only gets data, which enables the method to be invoked at component initialization and improves performance by reducing server round trips.
• The method cannot mutate the result set retrieved from the database, which means it cannot modify, insert, or delete any records. This ensures that the method is idempotent and can be cached safely.
• The method cannot use the @InvocableMethod annotation, which is reserved for methods that are exposed as actions in flows or processes. References:

Aura Components and Lightning Web Components are two technologies that are built on a framework that fully supports the business requirement of building a responsive application capable of responding to touch events, that will be executed on stateful clients. Both technologies are part of the Lightning Component Framework, which is a modern UI framework for developing dynamic web apps for mobile and desktop devices. The Lightning Component Framework uses standard web technologies, such as HTML, CSS, JavaScript, and Web Components, to create reusable and interoperable components that can adapt to different screen sizes, devices, and orientations. The framework also provides features such as data binding, event handling, state management, and server-side integration, to enable developers to create rich and interactive user interfaces.

Aura Components are the original technology for creating Lightning components. They use a custom XML-based markup language, Aura, to define the component structure and behavior. Aura Components can respond to touch events using the ui:input component, which provides a generic input element that can handle different input types, such as text, number, date, checkbox, radio, toggle, and email. The ui:input component also supports touch gestures, such as swipe, tap, and pinch, by using the ontouchstart, ontouchend, ontouchmove, and ontouchcancel attributes. Aura Components are stateful, meaning that they maintain their state on the client-side and communicate with the server only when necessary. This reduces the network traffic and improves the performance and user experience.

Lightning Web Components are the newer technology for creating Lightning components. They use standard HTML, CSS, and JavaScript to define the component structure and behavior. Lightning Web Components can respond to touch events using the standard HTML input element, which provides a native input element that can handle different input types, such as text, number, date, checkbox, radio, toggle, and email. The input element also supports touch gestures, such as swipe, tap, and pinch, by using the standard touch event listeners, such as touchstart, touchend, touchmove, and touchcancel. Lightning Web Components are also stateful, meaning that they maintain their state on the client-side and communicate with the server only when necessary. This reduces the network traffic and improves the performance and user experience.

Visualforce Components and Visualforce Pages are two technologies that are not built on a framework that fully supports the business requirement of building a responsive application capable of responding to touch events, that will be executed on stateful clients. Visualforce Components are reusable UI elements that can be used in Visualforce Pages. Visualforce Pages are web pages that can display and interact with Salesforce data and logic. Visualforce Components and Pages use a custom XML-based markup language, Visualforce, to define the UI elements and behavior. Visualforce Components and Pages can be made responsive by using the Salesforce Lightning Design System (SLDS), which is a collection of design guidelines, components, and resources that enable developers to create consistent and beautiful user interfaces across devices. However, Visualforce Components and Pages do not have native support for touch events, and require custom JavaScript code to handle them. Visualforce Components and Pages are also stateless, meaning that they do not maintain their state on the client-side and communicate with the server on every request. This increases the network traffic and affects the performance and user experience.

 A Full Sandbox is a type of sandbox that has a complete duplicate copy of the production org, including all the data and configuration. A Full Sandbox is useful for testing and development purposes, as it allows the developer to perform any changes or operations without affecting the production org. A Full Sandbox also supports performance testing, load testing, and staging1.

The other options are not correct because:

• A Developer Pro Sandbox is a type of sandbox that has a copy of the production org’s configuration (metadata) and some data. A Developer Pro Sandbox is limited by storage space and can only hold up to 1 GB of data1.
• A Partial Copy Sandbox is a type of sandbox that has a copy of the production org’s configuration and a sample of the data. A Partial Copy Sandbox is limited by storage space and can only hold up to 5 GB of data. The data is selected based on a sandbox template that defines the objects and records to include1.
• A Production org is not a duplicate copy of itself, but the original org where the live data and processes are stored. A Production org is not meant for testing or development purposes, as any changes or operations can affect the users and the business2.

A trace flag is a configuration that specifies the debug level, the start time, the end time, and the log type for a user, an Apex class, or an Apex trigger. The log types are DEVELOPER_LOG, USER_DEBUG, and CLASS_TRACING. A trace flag can be configured for Visualforce, Apex classes, and users to enable logging of their activities and events. For example, a trace flag can be set for a Visualforce page to capture the execution time, view state, and heap size. A trace flag can also be set for an Apex class or trigger to override the default logging level and capture more or less information. A trace flag can also be set for a user to monitor their actions and interactions with Salesforce. A trace flag cannot be configured for Process Builder or outbound messages, as they are not supported log types. References:

• Debug Log Levels from the Salesforce Help
• Set Up Debug Logging from the Salesforce Help

When deploying to a production org, all Apex code, including triggers, must have at least 75% test coverage. This means that at least 75% of the lines of code in each Apex class and trigger must be executed by unit tests. This is a requirement to ensure the quality and reliability of the code and to prevent any unexpected behavior or errors in production. Test coverage is calculated by dividing the number of covered lines by the total number of lines in each class or trigger. Test coverage can be measured by running tests in the Developer Console, the Salesforce CLI, or the Apex Test Execution page in Setup. Test coverage can also be viewed in the Code Coverage page in Setup or in the Problems tab in the Developer Console. Test coverage is different from test results, which indicate whether the tests passed or failed based on the assertions and expected outcomes. Test results do not affect the deployment, but they can help identify and fix any bugs or issues in the code. Test coverage and test results are both important aspects of testing Apex code and ensuring its functionality and performance. References:

• Get Started with Apex Unit Tests from the Salesforce Trailhead
• Deploying Apex to a Production Organization from the Apex Developer Guide

Quick Actions are the recommended way to create records with prepopulated values in Lightning Experience. They allow the developer to define the fields and values that should be populated when the user clicks the action. They also support different layouts and visibility rules for different profiles and record types. Quick Actions can be added to the page layout, the utility bar, or the global actions menu. References:

• [Quick Actions]: Learn how to create actions to automate common tasks and enhance the user experience.
• [Create Object-Specific Quick Actions]: Learn how to create quick actions that are specific to a particular object, such as creating a contact from an account.
• [Create Global Quick Actions]: Learn how to create quick actions that are not tied to a specific object, such as creating a task or logging a call.

The global access modifier declares that the class and method are known by all Apex code everywhere, not just within the same application or package namespace. This access modifier must be used for any method that must be referenced outside of the application, either in SOAP API or by other Apex code1. The other options are either incorrect or insufficient, as they do not guarantee the accessibility of the method outside the package namespace2. References:

• Access Modifiers | Apex Developer Guide | Salesforce Developers
• Global Modifier Accessing Public Elements in a Managed Package

 To use a custom exception, you can create an instance of the custom exception class and use the throw keyword to throw the exception. You can also optionally provide a custom error message or a chained exception cause as arguments to the custom exception constructor. The syntax for throwing a custom exception is:

throw new CustomException(optional_message, optional_cause);

Therefore, the options B and D are valid ways to fire the custom exception in Apex. The options A and C are invalid because they only create an instance of the custom exception class, but do not throw it. Also, the option C uses single quotes instead of double quotes for the error message, which is not allowed in Apex. References: You can find more information about custom exceptions in the Apex Developer Guide and the Apex Reference Guide on Salesforce’s official website. You can also read this blog post for a tutorial on creating and using custom exceptions.

The correct answer is option C. In Salesforce, a custom SOAP Web Service is defined using Apex with annotations that enable classes and methods to be exposed as web service endpoints. Helper methods that are not used by the Web Application should not be declared as webservice. They can be private or public but should not have the webservice keyword in their declaration. The webservice keyword is specifically for methods that are exposed to external applications via SOAP API.

References: The information can be referenced from the official Salesforce documentation on creating custom web services with Apex: Creating Custom Web Services.

A Lightning component can execute a complex SOQL query that joins two objects by invoking an Apex class with the method annotated as @AuraEnabled. This annotation enables the Apex method to be called from the Lightning component’s JavaScript controller or helper. The Apex method can then perform the SOQL query and return the results to the Lightning component. This approach allows the Lightning component to leverage the programmatic capabilities of Apex and SOQL to perform complex queries that are not possible with declarative tools such as flows or standard components. References:

Declarative development is the process of configuring and customizing the Salesforce platform using its built-in tools, such as the setup menu, without writing any code. Declarative development has the following advantages over programmatic customization, which involves writing custom code using Apex, Visualforce, or other languages:

• Declarative development can be done by anyone who knows how to use the Salesforce user interface, without requiring any programming knowledge or skills. Programmatic customization requires a skilled developer who knows how to write, test, and debug code.
• Declarative development does not require Apex test classes, which are mandatory for deploying any custom code to production. Apex test classes are used to verify the functionality and quality of the code, and to ensure that it meets the code coverage requirement of at least 75%. Declarative development does not have this requirement, as the platform automatically validates the configuration and customization.
• Declarative development is faster and easier to implement, as it involves clicking and dragging components, setting properties, and defining rules. Programmatic customization is more time-consuming and complex, as it involves writing lines of code, using development tools, and following coding standards and best practices.

However, declarative development also has some limitations and disadvantages compared to programmatic customization, such as:

• Declarative development has lower design limits and query limits than programmatic customization. Design limits are the maximum number of components, fields, objects, rules, etc. that can be used in a Salesforce org. Query limits are the maximum number of records that can be retrieved or manipulated in a single transaction. Programmatic customization can bypass some of these limits by using techniques such as dynamic SOQL, batch Apex, or asynchronous Apex.
• Declarative development has less flexibility and control over the functionality and user interface than programmatic customization. Programmatic customization can create custom logic, automation, integration, and user interface that are not possible or supported by the declarative tools. For example, programmatic customization can use Apex triggers to execute logic before or after a record is inserted, updated, deleted, or undeleted, while declarative development can only use workflow rules or process builder to execute logic after a record is created or updated.
• Declarative development can become difficult to maintain and troubleshoot as the complexity and number of components, rules, and dependencies increase. Programmatic customization can be more organized and modular, as it can use classes, methods, variables, comments, and annotations to structure and document the code.

Therefore, the best practice is to use a combination of declarative and programmatic development, depending on the use case and the requirements. The general rule of thumb is to use declarative development whenever possible, and use programmatic customization only when necessary or when it provides significant benefits.

• Add a new Create Records element. This is true because the developer needs to create a new Contact record and store its ID on the Opportunity record. A Create Records element allows the developer to create one or more records of a specific object type and assign values to the fields of those records1.
• Add a new Get Records element. This is false because the developer does not need to query any existing records from the database. A Get Records element allows the developer to find and store one or more records of a specific object type that meet certain criteria2.
• Add a new Update Records element. This is false because the developer already has an Update Records element in the flow that updates the Opportunity record. A Update Records element allows the developer to update one or more records of a specific object type that meet certain criteria3.
• Add a new Roll back Records element. This is false because the developer does not need to undo any changes made by the flow. A Roll back Records element allows the developer to roll back the changes made by the flow to the database if an error occurs.

A developer should use an Apex REST class to satisfy this requirement. An Apex REST class can expose a custom REST API that can be called from an external system, such as an order management system, to retrieve data in real time and return it in JSON or XML format1. The developer can then use the @InvocableMethod annotation on a method in the Apex REST class to make it available as an action in Flow Builder2. The developer can then use this action in the multi-screen flow to display the list of order number and dates on the screen for the call center agents. References:

• 2: Customize Order Management Flows Unit | Salesforce Trailhead

Adding system.debug statements to the code is a common and effective way to troubleshoot issues with Apex triggers. System.debug statements allow the developer to log messages, variables, or expressions to the debug log, which can be viewed in the Developer Console or other tools1. By adding system.debug statements at strategic points in the trigger code, the developer can track the execution flow, check the values of variables, and identify the root cause of the issue. Disabling the trigger in production is not a good practice, as it can affect the business logic and data integrity of the org2. Using the Apex Interactive Debugger is a powerful tool that allows the developer to set breakpoints, inspect variables, and execute code line by line, but it requires a paid license and a supported IDE3. Reviewing the Historical Event logs can provide useful information about the performance, security, and usage of the org, but it may not be sufficient to pinpoint the exact issue with the trigger4. References:

The sfdx commands that can be used to add testing data to a Developer sandbox are forced: data:bulk:upsert and forced: data:tree:upsert. The forced: data:bulk:upsert command uses Bulk API 2.0 to upsert records from a CSV file into an org1. The forced: data:tree:upsert command uses the SObject Tree Save API to import records from a JSON file that describes objects and relationships2. The forced: data:object:upsert command is not valid, and the forced: data:async:upsert command does not exist.

References:

• Salesforce CLI Command Reference - force:data:bulk:upsert

The correct answer is to move all of the logic to a Queueable class that queries for and updates the Assets and call it from the trigger. This is because when dealing with bulk data, triggers can often hit governor limits. By utilizing a Queueable class, the developer can perform asynchronous processing which helps in handling more records and avoiding hitting governor limits. References: The Salesforce Platform Developer I Learning documents emphasize on understanding the governor limits and how to write efficient code that can handle bulk data without hitting these limits. Asynchronous processing like Batch Apex, Future methods, or Queueable Apex is often recommended for bulk data handling. You can find more information on these topics in the following links: Apex Developer Guide, Trailhead

The fire() method is used to fire an Aura application event from a component controller or helper. This method takes the event instance as a parameter and broadcasts it to all components that are listening for that event type. The registerEvent() method is used to declare an event in a component markup, not to fire it. The emit() and fireEvent() methods are not valid methods for Aura application events. References:

• Aura Components Developer Guide: Firing Application Events, page 1
• Trailhead: Platform Developer I Certification Study Guide: Lightning Web Components, unit 5

 To allow reporting on which companies have reported which bugs, a junction object between Bug__c and Account is needed. A junction object is a custom object with two master-detail relationships, one to each of the objects it is joining. A junction object allows many-to-many relationships between objects, such as Bug__c and Account in this scenario. With a junction object, each bug can be related to multiple accounts, and each account can be related to multiple bugs. A roll-up summary field, a lookup field, or a master-detail field would not allow this kind of relationship, as they only support one-to-many or one-to-one relationships between objects. References:

• Define Relationships Between Custom Objects (Trailhead Module)
• Relationships Among Objects (Salesforce Developer Documentation)
• Free Salesforce Platform Developer 1 Practice Exam (With Answers) (Salesforce Ben)

 To create a form that will create a record for a custom object, the developer can use a Dynamic Form, which is a Lightning App Builder component that allows you to customize the fields and sections of a record page layout1. A Dynamic Form can also use visibility rules to display different fields based on the user’s profile, role, or other criteria2. To add the functionality to the Account record page, the developer can use a Dynamic Action, which is a way to configure actions on a record page without code3. A Dynamic Action can also use visibility rules to show or hide actions based on the user’s profile, role, or other criteria4. To restrict the functionality to a small group of users, the developer can create a Custom Permission, which is a way to grant access to custom processes or apps5. A Custom Permission can be assigned to a permission set or a profile, and then assigned to the users who need it. References:

You can render any page as a PDF by adding the renderAs attribute to the  component, and specifying "pdf" as the rendering service1. For example: . You can also use the PageReference.getContentAsPDF() method in Apex to render a Visualforce page as PDF data, and then use Apex code to convert that PDF data to an email attachment, a document, a Chatter post, and so on2. References:

A screen-based flow is a type of flow that allows you to create a guided, visual experience for users to collect and update data, execute logic, call Apex classes, and more. Screen-based flows are ideal for creating interactive processes that require user input and feedback, such as the scenario of processing damaged or stolen credit cards. A screen-based flow can be embedded in a Lightning page, a Visualforce page, a utility bar, or a custom tab, and can be launched from various places, such as a button, a link, a Lightning component, or a process. A screen-based flow can also leverage standard and custom objects, variables, formulas, and other elements to create dynamic and complex business logic. References: Screen-Based Flows Salesforce Platform Developer 1 Exam Guide, page 7.

An Apex REST class is a custom class that defines methods that can be invoked via HTTP requests. The developer can use the @RestResource annotation to expose the class as a REST resource, and use the @HttpGet, @HttpPost, @HttpPut, or @HttpDelete annotations to define the methods that correspond to the HTTP verbs. The developer can also use the RestContext class to access the request and response information, such as the parameters, headers, and body. An Apex REST class can be used to integrate with an external order management system by sending and receiving JSON or XML data, and parsing and serializing it using the built-in Apex methods. The developer can then use the flow:callApex action in the flow to invoke the Apex REST class and pass the data to the screen element. An Apex REST class is different from the other options listed, as they are not suitable for this requirement. An Apex controller is a class that provides logic and data for a Visualforce page or a Lightning component, not a flow. An outbound message is a message that is sent from Salesforce to an external system when a workflow rule is triggered, not when a flow is executed. An invocable method is a method that is annotated with @InvocableMethod and can be called from a process, a flow, or a REST API, but it cannot make HTTP requests to an external system. References:

• Apex REST Methods from the Apex Developer Guide
• Call Apex from Flow from the Salesforce Help
• Integrate with External Systems Using Apex REST Services from the Salesforce Trailhead

The developer should implement either a Lightning component or a Visualforce page that performs the HTTP REST callout, and use a Lightning Action or a Visualforce quick action to expose the component on the Opportunity detail page. These methods allow the developer to create a user interface that can capture the user input and trigger the callout based on a user-initiated action. The Lightning component or the Visualforce page can use the Apex controller to invoke the HTTP callout using the built-in HTTP classes, such as HttpRequest, HttpResponse, and Http. The Lightning Action or the Visualforce quick action can be added to the page layout of the Opportunity object and configured to display the component in a modal dialog or a panel.

Creating a Process Builder or an after update trigger to perform the HTTP REST callout is not a suitable method for this business requirement, because these methods do not provide a user interface or a user-initiated action. The Process Builder or the trigger would execute the callout whenever the Opportunity is updated, regardless of the user input or intention. This could result in unnecessary or unwanted callouts, as well as hitting the governor limits for callouts.

The developer should use the lightning-input-field component to support the security requirements. This component respects the field-level security and sharing settings of the Salesforce org, and displays the appropriate data to different types of users. The other components do not have this feature, and may expose sensitive data to unauthorized users. References: Lightning Web Components Developer Guide), Secure Coding Guide)

 Running a flow in debug mode allows the developer to test the flow logic and functionality before activating it. Debug mode also provides detailed information about the flow elements, variables, and outcomes as the flow runs1. However, there are some limitations and considerations for debugging a flow, such as:

• Callouts to external systems are not executed when debugging a flow. This means that any flow elements that invoke Apex actions or invocable actions that make callouts will be skipped during debugging. The developer can use mock responses or stubs to simulate the callout results2.
• DML operations will be rolled back when the debugging ends. This means that any changes made to the database by the flow will not be committed or visible after the debugging session. The developer can use the Developer Console or the Setup Audit Trail to view the DML operations performed by the flow3.

The other two options are incorrect because:

• Clicking Pause or executing a Pause element does not close the flow and end debugging. Instead, it pauses the flow execution and allows the developer to inspect the flow state and variables at that point. The developer can resume the flow execution by clicking Resume or Next4.
• Input variables of type record can be passed into the flow. The developer can specify the record ID or assign field values for the input record variable when debugging the flow. The developer can also use the running user or a different user as the input record variable.

This code is vulnerable to a cross-site scripting (XSS) attack, because it takes user-supplied input and outputs it directly back to the user without escaping the XSS-vulnerable characters, such as <, >, ", ', and &. By setting the escape attribute to false, the developer disables the anti-XSS filter that is enabled by default for most Visualforce tags. An attacker can exploit this vulnerability by injecting malicious HTML or JavaScript code into the userInput parameter, which can then execute on the user’s browser and compromise their security or privacy. References:

• Security Guidelines for Apex and Visualforce Development

 Validation rules and record-triggered flows are two declarative options for building out the business logic layer of a Salesforce application. Validation rules allow the developer to define criteria and error messages to prevent invalid data from being saved1. Record-triggered flows allow the developer to automate actions based on changes in records, such as creating, updating, or deleting related records2. Both of these options can be configured and maintained by a Salesforce administrator without writing code. References:

• Validation Rules, Trailhead module
• Record-Triggered Automation, Trailhead module

The correct option is C, which includes the import statement for an Apex method named updateAccounts in the class AccountController. In Salesforce, to use an Apex method in a Lightning Web Component (LWC), you need to import it using a specific syntax. The syntax includes the import keyword followed by the method name from '@salesforce/apex/ClassName.MethodName'. This makes the Apex method available for use within the LWC. References:

• 1: Order of Execution (Apex Developer Guide)
• 2: Use a Static Resource (Lightning Web Components Developer Guide)

• 5: How to call the apex method in lightning web component
• 6: Using Apex | Lightning Aura Components Developer Guide | Salesforce …

The TestVisible annotation allows test methods to access private or protected members of another class outside the test class. This way, the developer can write unit tests for a private method in an Apex class without changing the access modifier of the method. The SeeAllData annotation allows test methods to access all data in the organization, including records that are normally hidden from test methods. This is not related to testing private methods. Adding a test method in the Apex class is not a good practice, as it mixes production and test code in the same class. Marking the Apex class as global makes it accessible by any Apex code that has access to the class, not just test methods. This can expose the class to unwanted modifications or invocations. References:

• Apex Developer Guide: Isolation of Test Data from Organization Data in Unit Tests, page 1
• Apex Developer Guide: Testing Best Practices, page 1
• Apex Developer Guide: Annotation TestVisible, page 1
• [Trailhead: Platform Developer I Certification Study Guide: Apex Testing], unit 6

The developer can update the method to prevent a SOQL injection attack by using variable binding and replacing the dynamic query with a static SOQL, or by using the escapeSingleQuote method to sanitize the parameter before its use. These are two ways to avoid concatenating user input directly into the query string, which can allow malicious input to alter the query logic and expose sensitive data. For example, the developer can rewrite the method as follows:

// Using variable binding and static SOQL List performSearch(String lastName){ String queryName = ‘%’ + lastName + ‘%’; return [SELECT Id, FirstName, LastName FROM Contact WHERE LastName LIKE :queryName]; }

// Using escapeSingleQuote method List performSearch(String lastName){ String sanitizedLastName = String.escapeSingleQuotes(lastName); return Database.query(‘SELECT Id, FirstName, LastName FROM Contact WHERE LastName LIKE '%’ + sanitizedLastName + ‘%'’); }

Using a regular expression on the parameter to remove special characters is not a reliable way to prevent a SOQL injection attack, because it may not cover all possible scenarios and may also remove valid input. Using the @Readonly annotation and the with sharing keyword on the class is not relevant to the SOQL injection issue, because they affect the data access and performance of the class, not the security of the query.

References: SOQL Injection, Invoking Callouts Using Apex, Prepare for Your Salesforce Platform Developer I Credential

To deploy Apex code to a production environment, the developer must ensure that the Apex classes have at least 75% code coverage org-wide, and that all triggers have some code coverage. This means that at least one line of code must be executed for the Apex trigger during the test execution. Code coverage is a measure of how many lines of code are executed by the test methods. Code coverage helps to ensure that the Apex code works as expected and that it does not break any existing functionality. Code coverage also helps to prevent deploying code that has not been tested or that has bugs. All methods in the test classes must use @isTest or the testMethod keyword, but this is not a factor for deploying the modification, as it is a requirement for creating the test classes in the first place. The @isTest annotation and the testMethod keyword are equivalent ways of marking a method as a test method. Test methods are methods that verify the functionality of the Apex code and do not count against the code limit of the organization. References:

• Apex Developer Guide: Testing Apex, pages 1-2
• Trailhead: Platform Developer I Certification Study Guide: Apex Testing, unit 6

 To create a form that will create a record for a custom object, the developer can use a Dynamic Form, which is a Lightning App Builder component that allows you to customize the fields and sections of a record page layout1. A Dynamic Form can also use visibility rules to display different fields based on the user’s profile, role, or other criteria2. To add the functionality to the Account record page, the developer can use a Dynamic Action, which is a way to configure actions on a record page without code3. A Dynamic Action can also use visibility rules to show or hide actions based on the user’s profile, role, or other criteria4. To restrict the functionality to a small group of users, the developer can create a Custom Permission, which is a way to grant access to custom processes or apps5. A Custom Permission can be assigned to a permission set or a profile, and then assigned to the users who need it. References:

In Apex, if a SOQL query returns more than one row and the result is assigned to a single sObject variable, an exception will be thrown. This is because a single sObject variable can only hold one record. In this case, since myAccount is declared as a single Account object, it cannot hold more than one record. If the SOQL query returns more than one Account, an unhandled exception occurs, and the code terminates. References: The behavior can be understood from the Apex Developer Guide under the section of SOQL Queries 

To create a class that provides the capabilities defined by multiple interfaces, the class must use the implements keyword followed by a comma-separated list of the interface names. The class must also provide the implementation for all the methods declared in the interfaces. The extends keyword is used for inheritance, not for implementing interfaces. Therefore, option C is the correct implementation of the DrawList class that implements both the Sortable and Drawable interfaces. References: Interfaces | Apex Developer Guide, Cert Prep: Platform Developer I: Developer Fundamentals

The correct answer is option C, which is the upsert statement. In Salesforce, when you have a custom object and want to insert new records and update existing ones using an external ID field, you use the upsert DML operation. The upsert statement either inserts or updates sObject records based on the value of a specified unique external ID field. References: The information can be referenced from the official Salesforce documentation and learning materials available on Trailhead. Specifically, it aligns with the objectives outlined in data modeling and management, as well as Apex programming basics where DML operations are discussed. Salesforce DML Operations

The view state limit is the maximum size of the serialized version of the page state that can be transferred between the server and the client. The view state includes the components, field values, and controller state of the page. To reduce the view state size, a developer can use a StandardSetController, which allows the developer to create pagination for a set of records without having to manually manage the query and the results. A StandardSetController can handle up to 10,000 records, and only the records that are displayed on the current page are included in the view state. This way, the developer can avoid querying and storing all the records in a list variable, which would increase the view state size and potentially cause errors. References:

• Visualforce Developer Guide: StandardSetController Methods
• Visualforce Developer Guide: Working with Very Large SOQL Queries
• Trailhead: Visualforce Basics

The correct answers are C and D because they are the minimum requirements for deploying Apex code from a sandbox to production. According to the Salesforce documentation1, “To deploy Apex or package it for the AppExchange, at least 75% of your Apex code must be covered by unit tests, and all of those tests must complete successfully.” Additionally, “Every test method must use the System.assert methods to verify that the expected behavior occurs.” The other options are incorrect because they are not mandatory for deployment, but rather best practices or recommendations. Deploying during business hours may not be feasible or desirable for some organizations, depending on their availability and change management processes. Having at least one line of test coverage for each trigger is not enough to ensure code quality and functionality, and may not meet the 75% code coverage requirement. References:

• Apex Testing
• Deploy Apex
• Trailhead: Apex Testing

The exception type that cannot be caught is the LimitException. This exception is thrown when some governor limit is exceeded (like SOQL query limits, number of records that can be processed in a transaction, etc.). Salesforce doesn’t allow developers to catch LimitException in order to maintain the multi-tenant environment and ensure that no single tenant consumes excessive resources. References: Exception Class and Built-In Exceptions, Free Salesforce Platform Developer 1 Practice Exam (With Answers), SALESFORCE CERTIFIED PLATFORM DEVELOPER I

The Lightning Component framework is a UI framework for developing Lightning components for mobile and desktop devices. Lightning web components and Aura components can coexist and interoperate on a page1. The framework provides developers with prebuilt components that can be reused, such as buttons, cards, carousels, etc2. The framework also provides templates to create custom components that follow the best practices and standards of web development3. The framework does not extend the governor limits for applications, nor does it support Classic UI. It only supports Lightning Experience, Experience Builder Sites, Salesforce Mobile App, Lightning Out, and Standalone Lightning App2.

The optimal way to implement this feature is to build a flow with Flow Builder. Flow Builder is a tool that lets you automate business processes by creating flows that execute logic, interact with Salesforce, and call Apex classes. You can use Flow Builder to create a record-triggered flow that runs when an Account record is updated. In the flow, you can use a Get Records element to query the custom object based on the Postal Code field of the Account record. Then, you can use an Assignment element to assign the value of the Timezone field from the custom object record to the Timezone field of the Account record. Finally, you can use an Update Records element to save the changes to the Account record.

Option B is incorrect because an account assignment rule is used to automatically assign account owners based on criteria. It does not update other fields on the account record.

Option C is incorrect because a formula field is a read-only field that derives its value from a formula expression. It cannot be updated by the user or by a trigger.

Option D is incorrect because an account approval process is used to require approval from one or more users before an account record can be saved. It does not update other fields on the account record.

References: Flow Builder (Trailhead)), Record-Triggered Flows (Trailhead)), Account Assignment Rules (Salesforce Help)), Formula Fields (Salesforce Help)), Approval Processes (Salesforce Help))

The code snippet provided in the image is a Salesforce Apex code that is used to create new accounts in a Salesforce org. Initially, there are five existing accounts. In the provided Apex code, one account named ‘MyAccount’ is created and inserted into the org, making the total six accounts. Then, a loop is executed to create and add ten more new accounts (named ‘New Account 1’ to ‘New Account 10’) into the org using a do-while loop that runs while x is less than 10 (starting from x=1). So, after executing this code, there will be an additional eleven accounts added to the initial five accounts making it a total of fifteen (5 initial + 11 new = 16) accounts in the org. References: The explanation can be corroborated with knowledge of Apex programming on Salesforce’s official learning platform Trailhead and related documentation.

 Developer Edition orgs are free, fully-featured copies of Salesforce that are designed for developers to create and test applications. They have the same configuration as the production org, but with limited data and file storage. Developer Edition orgs are ideal for individual developers or small teams who want to work in their own orgs that are isolated from each other. Full Sandbox orgs are also copies of the production org, but they require a paid license and have a refresh interval of 29 days. Partner Developer Edition orgs are similar to Developer Edition orgs, but they have higher limits on data and file storage, as well as the number of custom objects and tabs. They are available only to Salesforce partners who are enrolled in the Partner Program. Developer Sandbox orgs are copies of the production org metadata, but they have very limited data and file storage, and a refresh interval of one day. They are useful for coding and testing in a disposable environment, but not for developing complex applications that require more resources. References:

Apex test methods should not depend on existing data in the sandbox, because they may not have access to the same data when they run in a different environment, such as production. Test methods should create their own test data, or use the @testSetup annotation to create common test data for all test methods in a class12. The Execute Anonymous tool runs the code in the context of the current user and the current data, so it may not reproduce the same behavior as the test method3. References:

To communicate from a child component to a parent component, the best option is to create a custom event in the child component and dispatch it to the parent component. The parent component can then listen for the event and handle it accordingly. For example, the child component can create a custom event called navigate and pass the page reference as a detail. The parent component can then use a handler to catch the event and use the navigation service to navigate to the next page.

Option A is incorrect because firing a notification is not a reliable way to communicate between components, as it depends on the user’s settings and preferences. Option B is incorrect because updating a property on the parent component requires the child component to have access to the parent’s property, which violates the principle of component encapsulation and modularity. Option C is incorrect because calling a method in the Apex controller is not necessary for navigation purposes, and it would introduce an extra server round-trip and potential performance issues.

References: Communicate with Events | Lightning Web Components Developer Guide, Basic Navigation | Lightning Web Components Developer Guide, Cert Prep: Platform Developer I: Lightning Web Components

 To calculate the estimated ship date for an Order, the best method is to use a Max Roll-Up Summary field on the Latest availability date fields. A Roll-Up Summary field calculates values from related records, such as the sum, minimum, maximum, or count of a field1. By using a Max Roll-Up Summary field on the Latest availability date fields, the Order record can display the latest date among all the Line Items, which is the earliest date that the Order can be shipped.

The other options are not correct because:

• A. Use a CEILING formula on each of the Latest availability date fields. This option is not valid, because a CEILING formula rounds a number up to the nearest integer2. This does not help to calculate the estimated ship date for an Order, as it does not compare the dates of the Line Items or display the result on the Order record.
• B. Use a DAYS formula on each of the availability date fields and a COUNT Roll-Up Summary field on the Order. This option is not valid, because a DAYS formula returns the number of days between two dates2. This does not help to calculate the estimated ship date for an Order, as it does not account for the latest date among the Line Items or display the result on the Order record. A COUNT Roll-Up Summary field only counts the number of related records, not the values of a field1.
• C. Use a LATEST formula on each of the latest availability date fields. This option is not valid, because there is no such formula function as LATEST in Salesforce2. Even if there was, it would not help to calculate the estimated ship date for an Order, as it would not display the result on the Order record.

Using the Database method with all or None set to false allows the developer to insert the Task records without throwing an exception if some of them fail. This way, the integration can read the task records that were successfully inserted, and the developer can handle the failed records in the trigger or elsewhere. The other options are either too disruptive to the business logic (A and C) or do not prevent the exception from occurring (B). References: Database Methods, Bulk Exception Handling, Trigger Exceptions
