CAD Certified Application Developer - ServiceNow Questions and Answers

User-defined non-inherited fields can be deleted from a table in ServiceNow. These are fields that are created by users on a specific table and are not inherited from a parent table. Inherited fields cannot be deleted from a table, as they are defined on a parent table and shared by all child tables. Any field on a table cannot be deleted, as some fields are system-defined and essential for the table functionality. Table records are not deleted when a field is deleted, as the field deletion only affects the table structure and not the data. Reference: Delete fields

The Automated Test Framework (ATF) is a tool that allows you to create and run automated tests on the ServiceNow platform. The ATF uses test steps to define the actions and validations for each test. The test step that allows you to create a user with specified roles and groups for the test is the Create a user test step. This test step creates a temporary user record that is deleted at the end of the test. You can specify the user name, password, roles, and groups for the user. You can also use the Impersonate a user test step to switch to the created user and perform actions as that user.

The other options are not valid test steps for creating a user. The Create a role and Create a group test steps do not exist in the ATF. To create a role or a group, you need to use the Create a record test step and specify the sys_user_role or sys_user_group table. The Impersonation test step does not create a user, but switches to an existing user.

The Field Watcher is a debugging tool that allows you to monitor the values of fields on a form as they change due to scripts or other actions. It can be used to debug Business Rules, Client Scripts, and Access Controls, but not Script Includes. Script Includes are server-side scripts that define reusable functions and classes. They are not associated with any specific field or form, and therefore cannot be watched by the Field Watcher.

Application Access is a feature that allows you to control the access level of other application scopes to your application’s data tables. You can use Application Access to control the following database operations:

• Create: This operation allows the user to create new records on the table. You can enable or disable this operation by selecting or clearing the Can create option.
• Delete: This operation allows the user to delete existing records on the table. You can enable or disable this operation by selecting or clearing the Can delete option.
• Read: This operation allows the user to view the records on the table. You can enable or disable this operation by selecting or clearing the Can read option.
• Write: This operation allows the user to modify the records on the table. You can enable or disable this operation by selecting or clearing the Can write option.

The one database operation that cannot be controlled with Application Access is Query. Query is not an operation, but a method of the GlideRecord class that is used to retrieve records from the database on the server-side. Query is not part of the Application Access rules, but it is affected by the Access Controls and the user’s roles.

There is no "copy" button on the application record (at least I couldn't see one). Also, see here: https://docs.servicenow.com/bundle/sandiego-application-development/page/build/applications/reference/r_ManagingApplications.html

To receive email notifications, a user must have an active account and a valid email address in the user record. If either of these conditions is not met, the user will not be able to receive any email notifications from the system.

To link a ServiceNow application to a Git repository, you need to provide the user name, URL, and password of the Git account that hosts the repository12. The URL is the address of the Git repository that you want to link to the application. The user name and password are the credentials that you use to access the Git account. Alternatively, you can use a personal access token instead of a password for increased security3.

Administrators can grant non-admin users the ability to develop global applications. Delegated Development is for the scoped applications only

https://docs.servicenow.com/bundle/tokyo-platform-administration/page/administer/platform-events/reference/r_ScriptActions.html

gs.print() and gs.log() are older and not available in scoped applications, whereas gs.debug(), gs.info(), gs.warn(), gs.error() work in both scoped applications and global are therefore are more versatile going forward in future versions.

The fastest way to create and configure a Record Producer is to open the table in the Table records and select the Add to Service Catalog Related Link. This will automatically create a Record Producer with the same fields as the table and add it to the Service Catalog. You can then modify the Record Producer as needed. The other options require more steps and manual configuration. Reference: Create a record producer

The statement that is not true for Modules is that every Module must be associated with a table. A Module is the functionality within an Application Menu that opens a content page in the content frame or a separate tab or window. A Module can be associated with a table, a list, a form, a report, a script, or any other type of page. For example, the Open Module under the Incident Application Menu opens a list of incident records from the Incident table, while the Overview Module under the Performance Analytics Application Menu opens a dashboard page with various charts and widgets. The other statements are true for Modules. Access to Modules is controlled with roles, as each Module can have one or more roles specified in its definition that determine who can see and access it. Modules open content pages, as they are links to different types of pages that provide information and functionality to users. Every Module must be part of an Application Menu, as they are the second-level navigation options for Applications. Reference: Modules

A Module Link type defines how the module opens in the content pane when the user clicks on it in the navigation pane1. The URL (from Arguments) link type allows you to specify a URL that opens the Application Properties page for the selected application2. The URL can include arguments that are evaluated at runtime, such as the application name or scope3.

An example of when an application might not use a Scheduled Script Execution (Scheduled Job) is when the application needs to run a client-side script at the same time every day. A Scheduled Script Execution is a server-side script that runs on a specified schedule and performs some action on the server or database. A client-side script runs on the user’s browser and cannot be scheduled by ServiceNow. The other options are examples of when an application might use a Scheduled Script Execution, such as sending email reminders, running a clean up script, or querying the database for unassigned records. Reference: Scheduled Script Execution, Client scripts

An application admin is a role that grants full access to an application and its tables, scripts, and other components1. An application admin can create, modify, and delete any element of the application, as well as publish and install it2. An application typically has an application admin role that is automatically created and assigned to the application creator3.

https://docs.servicenow.com/bundle/rome-application-development/page/build/applications/concept/c_ApplicationScope.html

The correct statement regarding Application Scope is that applications downloaded from 3rd party ServiceNow application developers cannot have naming conflicts. Application Scope is a feature that identifies and isolates applications and their related artifacts from other applications. Each scoped application has a unique namespace identifier that consists of a prefix and a scope name. This prevents cross-application name collisions and ensures that only authorized scripts can access or modify data in a scoped application.

The Guided Application Creator (GAC) is a tool that helps you create applications on the ServiceNow platform by guiding you through the steps of defining the data model, user interface, and logic. When using the GAC, you can designate data tables in three ways:

• Upload an existing PDF: You can upload a PDF file that contains the table schema and sample data. The GAC will parse the PDF and create the table and fields based on the file content.
• Create a new table on the platform: You can create a new table on the platform by specifying the table name, label, and description. You can also add fields, indexes, and relationships to the table using the GAC.
• Upload an existing spreadsheet: You can upload a spreadsheet file that contains the table schema and sample data. The GAC will parse the spreadsheet and create the table and fields based on the file content.

The other options are not valid ways to designate data tables when using the GAC. You cannot upload an existing word processing document or use a freeform database. You can use an existing table on the platform, but you cannot designate it as a data table. You can only use it as a reference table for lookup fields.

Catalog Client Scripts and Catalog UI Policies are the client-side scripts that apply to Record Producers. Catalog Client Scripts allow you to add or modify functionality on a catalog item or record producer form. Catalog UI Policies dynamically change information on a catalog item or record producer form. UI Scripts, UI Actions, Client Scripts, and UI Policies do not apply to Record Producers. Reference: Catalog client scripts, Catalog UI policies

A spoke is a scoped application that contains flow actions that can be used in Flow Designer. Spokes allow developers to create reusable actions that can be shared across applications and instances.

The application name is not required to link a ServiceNow application to a Git repository. You only need to provide the URL, user name, and password of the Git repository, as well as the branch name and the authentication type. The application name is automatically generated based on the scope name of your application. Reference: [Link an application to a Git repository]

The steps to import new data into ServiceNow from a spreadsheet are: Load Data, Create Transform Map, Run Transform. Load Data is the process of uploading the spreadsheet file and creating an Import Set table that contains the data to be imported. Create Transform Map is the process of defining how the fields from the Import Set table map to the fields of the target table in ServiceNow. Run Transform is the process of executing the Transform Map and copying the data from the Import Set table to the target table. Reference: Import sets, Transform maps

Access Control scripts are server-side scripts that run when an Access Control rule is evaluated. They can use the gs and current objects to access the GlideSystem and GlideRecord methods, respectively. Some of the useful methods in Access Control scripts are:

• gs.hasRole() - This method checks if the current user has a specified role. It returns true if the user has the role, and false otherwise. For example, gs.hasRole(‘admin’) will return true if the user is an administrator, and false otherwise.
• current.isNewRecord() - This method checks if the current record is a new record that has not been inserted into the database yet. It returns true if the record is new, and false otherwise. For example, current.isNewRecord() will return true if the record is being created, and false if the record is being updated or deleted.

The methods g_user.hasRole() and current.isNew() are not part of the server-side scripting API. They are part of the client-side scripting API, which is used in Client Scripts and UI Policies. They cannot be used in Access Control scripts.

The following roles grant access to source control repository operations such as importing applications from source control, or linking an application to source control:

• source_control. This is a role that allows users to perform basic source control operations, such as importing an application from a source control repository, updating an application from a source control repository, or committing changes to a source control repository.
• admin. This is a role that grants full access to all the features and functions of the ServiceNow platform, including source control operations. Users with this role can also perform advanced source control operations, such as creating or deleting source control repositories, configuring source control properties, or resolving conflicts.

The following roles do not grant access to source control repository operations:

• source_control_admin. This is not a valid role in ServiceNow. There is no separate role for source control administration, as this function is included in the admin role.
• git_admin. This is not a valid role in ServiceNow. Git is a specific type of source control system that ServiceNow supports, but there is no role dedicated to Git administration. References: Source Control, Source Control Roles

Flow Designer is a no-code platform capability that lets you automate business processes in a single drag-and-drop design environment. Some of the features of Flow Designer are:

• Add stages to a flow: You can define the stages of a flow to track its progress and status. Stages can be used to group actions, subflows, and conditions into logical units.
• Call a flow from another flow or subflow: You can reuse existing flows or subflows by calling them from another flow or subflow. This allows you to modularize your automation and avoid duplication of logic.
• Test a flow using the “Run as” feature: You can test a flow using the “Run as” feature to specify the user context and input parameters for the flow execution. This helps you to verify the functionality and performance of your flow before publishing it.

The method call that returns true only if the currently logged in user has the catalog_admin role and in no other case is g_user.hasRoleExactly(‘catalog_admin’). This method checks if the user has exactly one role, and returns true if it matches the argument. The other methods return true if the user has one or more roles, or if the user has any role from a list of arguments. References: [ServiceNow Docs - GlideUser API], [ServiceNow Community - Difference between hasRole() and hasRoleExactly()]

 The application development plan is a document that outlines the scope, objectives, deliverables, and timeline of a software project1. It should include the following business requirements and processes:

• Data input/output: This describes what data is needed for the application to function, how the data is collected, stored, processed, and displayed, and what outputs are generated by the application2.
• Business problem: This defines the problem or opportunity that the application aims to address, the current situation, the desired outcome, and the benefits of the solution3.
• Process steps: This details the steps involved in the application development lifecycle, such as planning, designing, testing, deploying, and maintaining the application4.
• Users/stakeholders: This identifies the people who will use, benefit from, or influence the application, their roles, responsibilities, and expectations, and how they will be involved in the project5.

 Tables that extend a table inherit the parent’s fields. Extending a table means creating a child table that shares the same columns and business logic as the parent table. For example, the Incident table extends the Task table, which means that all fields defined on the Task table are also available on the Incident table. Extending a table allows for reusing existing fields and behaviors without duplicating them on multiple tables. Reference: Table extension and classes
