CAD Certified Application Developer - ServiceNow Questions and Answers

The purpose of application scoping is NOT to provide a way of tracking the user who developed an application. Application scoping does not store or display information about the user who created or modified an application or its artifacts. The purpose of application scoping is to provide a relationship between application artifacts, provide a namespace to prevent cross-application name collisions, and provide controls for how scripts from another scope can alter tables in a scoped application. References: [Product Documentation | ServiceNow], [Advantages of Scoped Applications in ServiceNow]

In ServiceNow, UI Actions are elements that make the user interface more interactive and tailored to user activities. They can appear as buttons, links, or context menu items on forms and lists. The valid types of UI Actions include:

C. Form choice: These are UI Actions that appear as choices in form context menus, allowing users to perform specific actions related to the form.

D. Form button: These are buttons that appear on forms, enabling users to execute defined actions directly from the form view.

E. List banner button: These are buttons that appear in the list view's banner, providing actions that can be performed on the list or selected records.

The other options are not standard UI Action types:

A. Workflow action: While workflows can include actions, "Workflow action" is not a defined UI Action type in ServiceNow.

B. Record navigation button: This is not a standard term used for UI Action types in ServiceNow.

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.

It is possible to change an application’s scope in ServiceNow, either from global to private or from private to global. However, changing the scope of an application may affect its functionality and compatibility with other applications. Therefore, it is recommended to test the application thoroughly before and after changing its scope.

Application Access settings in ServiceNow control which operations are permitted on a table by other applications. The following operations can be restricted:

Query (A) - Valid: Controls whether other applications can read (query) records from the table.

Create (B) - Valid: Determines whether other applications can add new records to the table.

Execute (C) - Incorrect: No such operation exists for Application Access.

Update (D) - Incorrect: "Update" permissions are controlled through Access Control Lists (ACLs), not Application Access settings.

The Form Designer is a tool that allows you to create and customize forms on the ServiceNow platform. The Form Designer has four main components:

Form layout: The form layout shows the preview of the form and allows you to drag and drop fields, sections, and related lists onto the form. You can also resize, reorder, and delete the elements on the form layout.

Page header: The page header shows the name of the table and the form that you are editing. You can also access the form properties, save the form, and switch to the form view from the page header.

Field navigator: The field navigator shows the list of available fields for the table and allows you to search, filter, and add fields to the form. You can also create new fields and edit existing fields from the field navigator.

Schema map: The schema map is not part of the Form Designer. The schema map is a separate tool that shows the relationships between tables and fields on the platform. You can access the schema map from the System Definition > Tables module or from the context menu of a table.

In ServiceNow, UI Actions are elements such as buttons, links, and context menu items that allow users to perform actions on records or lists. The three valid UI Action types are:

1. List Banner Button (Option A)

Description: A button that appears in the list view header, allowing users to trigger an action affecting multiple records at once.

Example: A "Bulk Approve" button that processes selected records.

2. Form Button (Option B)

Description: A button that appears on a form, allowing users to trigger actions related to the current record.

Example: A "Submit for Approval" button on an incident form.

3. Record Navigation Button (Option D)

Description: A button that helps users navigate between related records.

Example: A "Go to Parent Record" button that redirects users to a linked record.

Incorrect Options:

Form Choice (Option C):

Not a UI Action type. Choices are typically used in choice fields (dropdowns) rather than UI actions.

List Choice (Option E):

Not a valid UI Action type. Similar to "Form Choice," it pertains to field options rather than UI elements.

Workflow Action (Option F):

Workflows are process automation tools, not UI Actions. They are not directly related to buttons or links that users interact with.

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.

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.

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

The following is true for a Script Include with a Protection Policy value of Protected:

The Protection Policy is applied only if the application is downloaded from the ServiceNow App Store. This is true because the Protection Policy is a feature that allows developers to protect their Script Includes from being viewed or modified by other users when they distribute their applications through the ServiceNow App Store. The Protection Policy is only enforced when the application is installed from the App Store, not when it is developed or tested on the instance.

The following are not true for a Script Include with a Protection Policy value of Protected:

Any user with the protected_edit role can see and edit the Script Include. This is false because the protected_edit role is not related to the Protection Policy, but to the Access Control (ACL) rules. The protected_edit role allows users to edit protected fields on a table, such as the script field on the sys_script table, which stores the Business Rules. The Protection Policy does not use roles to control access to the Script Includes, but a cryptographic key that is generated when the application is published to the App Store.

The Protection policy option can only be enabled by a user with the admin role. This is false because the Protection policy option can be enabled by any user who has the application_admin role for the scoped application that contains the Script Include. The application_admin role grants full access to the application development and administration within the scope of the application.

The Protection Policy is applied only if the glide.app.apply_protection system property value is true. This is false because the glide.app.apply_protection system property is not related to the Protection Policy, but to the Application Restricted Caller Access (ARCA) feature. The ARCA feature allows developers to restrict the access to the Script Includes from other applications based on the caller’s scope. The glide.app.apply_protection system property determines whether the ARCA feature is enabled or disabled on the instance. References: Script Includes, Protect Script Includes, Application Restricted Caller Access

A benefit of creating an Application Properties page for each application you develop is that Application Properties allow a developer or admin to make changes to an application’s behavior without modifying application artifacts. Application Properties are system properties that store configuration information for a specific application. They can be used to control various aspects of the application, such as feature flags, default values, thresholds, or URLs. By creating an Application Properties page, you can group and display all the properties related to your application in one place and make them easy to access and update. This way, you can avoid hard-coding static data in your application code and make your application more flexible and maintainable. Reference: Working with System Properties, Organizing your ServiceNow System Properties

A Record Producer in ServiceNow is a specific type of catalog item that enables users to create records in a particular table through a simplified interface. They are often used to allow users to create task-based records, such as incidents or change requests, from the Service Catalog.

servicenow.com

Key characteristics of Record Producers include:

Graphics can be included on the user interface: Developers can enhance the user experience by adding images or icons to the Record Producer form, making it more intuitive and visually appealing.

Each field prompts the user with a question rather than a field label: Instead of standard field labels, Record Producers can present fields as questions to guide users in providing the necessary information. This approach makes the form more user-friendly and context-specific.

You can script behaviors of fields in the user interface: Developers have the flexibility to add client-side scripts to control the behavior of fields on the Record Producer form. This capability allows for dynamic interactions, such as showing or hiding fields based on user input or pre-populating fields with specific data.

Option A is incorrect because records created by a Record Producer are inserted into the table specified during its configuration, not necessarily the Requested Item [sc_req_item] table. Option C is incorrect because scripting is not mandatory for Record Producers; they can function without additional scripting, although scripting can be used to enhance functionality when needed.

Business Rule is server-side, so it uses GlideSystem API. gs.hasRoleExactly doesn't exist

In a Business Rule, the following returns true if the currently logged in user has the admin role:

gs.hasRole(‘admin’). This is the correct answer because gs is the GlideSystem object, which provides methods for performing system operations, and hasRole is a method that checks if the current user has the specified role. For example, gs.hasRole(‘admin’) will return true if the current user has the admin role, and false otherwise.

The following do not return true if the currently logged in user has the admin role in a Business Rule:

g_form.hasRoleExactly(‘admin’). This is not correct because g_form is the GlideForm object, which provides methods for manipulating forms, and hasRoleExactly is a method that checks if the current user has exactly the specified role and no other roles. For example, g_form.hasRoleExactly(‘admin’) will return true if the current user has only the admin role, and false if the current user has the admin role and any other role.

g_form.hasRole(‘admin’). This is not correct because g_form is the GlideForm object, which provides methods for manipulating forms, and hasRole is a method that checks if the current user has the specified role or any role that contains the specified role. For example, g_form.hasRole(‘admin’) will return true if the current user has the admin role or any role that contains the admin role, such as admin_ui or admin_script.

gs.hasRoleExactly(‘admin’). This is not correct because gs is the GlideSystem object, which provides methods for performing system operations, and hasRoleExactly is not a valid method of the gs object. There is no method that checks if the current user has exactly the specified role and no other roles in the gs object. References: Business Rules, GlideSystem, GlideForm

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

To include specific records from a table (often referred to as seed data) when distributing an application in ServiceNow, developers must add these records to the application as application files. This ensures that when the application is installed on another instance, the specified records are included.

Option C is correct because using the "Create Application Files" feature allows developers to select specific records to include in the application package. This process creates application files for the selected records, ensuring they are installed along with the application on other instances.

Options A, B, and D are incorrect:

A: The activation status of Table A and whether it extends the Task table do not determine whether its records are included during installation.

B: Having an automatic number counter and setting a table property do not control the inclusion of records in the application package.

D: The System Clone > Exclude Tables list pertains to cloning operations and does not affect application installation.

For detailed guidance on including table records in application deployments, refer to the official ServiceNow documentation:

SERVICENOW.COM

Application Access is a feature that allows you to control the access level of other application scopes to your application’s data tables. By selecting the Allow access to this table via web services option, you can enable other application scopes to access your data tables using web services, such as SOAP or REST. However, the user performing the query via web services must have the correct permissions to access the table’s records. The user must have the appropriate roles and access controls to perform the operations on the table, such as create, read, write, or delete.

The other statements are not true when this option is selected. This option does not restrict the ability to delete records via web services, nor does it allow records to be always read. The access to the records depends on the user’s permissions and the web service method. This option also does not restrict access only to SOAP web services, but applies to both SOAP and REST web services. Finally, this option is not the only way to enable web service access to the table’s records. Even when this option is not selected, users with the correct permissions can use web services to access the table’s records, as long as they specify the application scope in the web service request.

In ServiceNow, Access Controls (ACLs) determine the permissions required for users to access or modify data. For a user to pass an Access Control, the following conditions must be met:

Conditions configured in the Access Control must evaluate to true: Access Controls can have specific conditions set in the "Condition" field. These conditions are evaluated against the current record, and must return true for the Access Control to grant access.

The user has one of the roles specified in the Required roles related list: Access Controls can specify certain roles that a user must possess to gain access. If the user holds at least one of these roles, this criterion is satisfied.

Scripts configured in the Access Control must evaluate to true: Access Controls can include scripts that perform more granular checks. The script must execute without errors and return true for the user to pass the Access Control.

Option A is incorrect because Business Rules do not grant access; they are server-side scripts that execute based on record operations but do not control security permissions.

Option D is misleading. Each Access Control is evaluated independently. While multiple Access Controls can apply to a single operation, passing one does not inherently grant access unless it is the most specific match.

For more detailed information, refer to the official ServiceNow documentation on Access Controls:

servicenow.com

In ServiceNow, the GlideSystem (gs) object provides several methods for logging messages in server-side scripts. In a privately-scoped application, the following methods are commonly used:

A. gs.log(): This method logs a message to the system log (syslog table). It is a general-purpose logging method that allows developers to record informational messages.

E. gs.info(): This method logs informational messages to the system log. It is functionally similar to gs.log() but is specifically intended for informational messages.

The other options are not standard methods provided by the GlideSystem object:

B. gs.error(): This method does not exist in the GlideSystem API.

C. gs.debug(): This method does not exist in the GlideSystem API.

D. gs.logError(): This method does not exist in the GlideSystem API.

For more detailed information, refer to the official ServiceNow documentation on the GlideSystem API.

In ServiceNow, when an event is generated using the gs.eventQueue() method, the system can respond in several ways:

B. Email Notification: Events can trigger email notifications. By associating an event with a notification, the system can send emails to specified recipients when the event occurs.

E. Script Action: Script Actions are server-side scripts that execute in response to events. They allow developers to define custom behaviors that should occur when specific events are fired.

The other options are not appropriate responses to events generated by gs.eventQueue():

A. UI Policy: UI Policies are used to dynamically change the behavior of fields on forms in the user interface and are not triggered by events.

C. Client Script: Client Scripts run on the client side (in the user's browser) and are not directly triggered by server-side events.

D. Scheduled Script Execution (Scheduled Job): Scheduled Jobs are scripts that run at specified times or intervals and are not triggered by events.

For more detailed information, refer to the official ServiceNow documentation on Responding to Events.

In ServiceNow, a workflow context refers to a specific instance of a workflow execution. When a workflow is initiated—whether by inserting or updating a record, triggering an event, or through scripts—the system creates a workflow context. This context is derived from a particular version of the workflow and is responsible for executing the defined activities and following the specified transitions within that workflow.

Key points about workflow context:

Instance of Execution: Each time a workflow runs, a new context is created to manage that specific execution instance. This allows multiple instances of the same workflow to operate independently and simultaneously.

Execution of Activities: The context manages the progression through the workflow's activities, ensuring that each step is executed in the defined order and under the specified conditions.

Tracking and Management: Workflow contexts enable administrators to monitor the state and progress of workflow executions. They provide visibility into which activities have been completed, which are pending, and any transitions that have occurred.

For example, if a workflow is designed to handle approval processes, each time an approval is initiated, a new workflow context is created to manage that particular approval instance. This context will track the approval's progress, manage notifications, and handle any branching logic defined in the workflow.

 When configuring a REST Message, the Endpoint is:

The URI of the data to be accessed, queried, or modified. This is the correct answer because the Endpoint is the part of the REST Message that specifies the location and the resource of the REST provider. The Endpoint is composed of the base URL and the resource path, which can include query parameters or variables. For example, the Endpoint for a REST Message that retrieves the weather information for a city from a web service could be https://api.openweathermap.org/data/2.5/weather?q=London.

The following are not correct definitions of the Endpoint when configuring a REST Message:

The commands to the REST script to stop execution. This is not correct because the commands to the REST script to stop execution are not part of the REST Message, but of the Scripted REST API, which is a feature that allows users to create custom REST endpoints on the ServiceNow platform. The commands to the REST script to stop execution are methods of the RESTAPIResponse object, such as setStatusCode, setError, or complete.

Information about the format of the returned data. This is not correct because the information about the format of the returned data is not part of the Endpoint, but of the HTTP headers or the Accept field of the REST Message. The HTTP headers or the Accept field can be used to specify the content type of the response, such as JSON, XML, or HTML.

The response from the provider indicating there is no data to send back. This is not correct because the response from the provider indicating there is no data to send back is not part of the Endpoint, but of the HTTP status code or the response body of the REST Message. The HTTP status code or the response body can be used to indicate the result of the REST request, such as 200 OK, 404 Not Found, or 500 Internal Server Error. References: REST Messages, Scripted REST APIs

Inherited fields in ServiceNow are fields that are part of a parent table and automatically become part of child tables through inheritance. This structure is foundational in the ServiceNow data model, ensuring that child tables maintain a consistent relationship with their parent tables.

Here’s why inherited fields cannot be deleted from a child table:

System Design:ServiceNow employs a table inheritance model where child tables derive fields and properties from parent tables. Deleting inherited fields from a child table would break the integrity of the data model, as those fields are shared across multiple tables.

Impact on Functionality:Many inherited fields, such as sys_created_on or sys_updated_by, are integral to the functionality of the platform. Removing them could disrupt workflows, reporting, and auditing capabilities.

Alternative Approach:If you want to hide or restrict access to inherited fields in a child table, you can use ACLs (Access Control Lists) to prevent users from viewing or modifying these fields. Another option is to use UI Policies or Client Scripts to control their visibility on forms.

Developer Note:Attempting to delete inherited fields violates ServiceNow’s core principles of maintaining a robust and unified data structure. The platform enforces these rules to ensure consistent behavior across all tables in the hierarchy.

ServiceNow Developer Documentation on Table Inheritance​.

Best practices outlined on SN Pro Tips regarding scoped application development and table structures​.

A Module in ServiceNow is a navigational element within an Application Menu that directs users to specific records, lists, forms, or reports.

Option A (Correct): Modules always belong to an Application Menu, providing structured navigation.

Option B (Incorrect): Modules can link to pages, reports, and URLs, not just tables.

Option C (Incorrect): Modules can open forms, lists, dashboards, and external URLs.

Option D (Incorrect): Modules can be restricted by roles, limiting visibility and access.

In ServiceNow, UI Actions are elements that facilitate user interaction within the platform, enabling users to perform specific actions such as form submissions, record updates, or triggering workflows. The valid types of UI Actions include:

Form Button: A button displayed on a form that, when clicked, executes a defined action.

Form Context Menu: An option added to the context menu of a form, providing additional actions related to the form's record.

Form Link: A hyperlink on a form that directs users to another page or executes a script.

List Banner Button: A button displayed in the banner area of a list, allowing actions to be performed on multiple records simultaneously.

List Choice: An option added to the list context menu for individual records, enabling actions on a selected record.

List Link: A hyperlink in a list that directs users to another page or executes a script.

Record Navigation Button: Buttons that facilitate navigation between records, such as Next and Previous buttons.

Options like "Workflow action" and "Form choice" are not recognized as standard UI Action types in ServiceNow.

For comprehensive details, refer to the official ServiceNow documentation on UI Actions.

In ServiceNow, when importing data from external sources, the data is first loaded into an Import Set table, which acts as a staging area. To move this data into an existing ServiceNow table (known as the target table), a Transform Map is used. A Transform Map is a set of field mappings that define the relationships between fields in the Import Set table and fields in the target table. This mapping ensures that data is accurately transformed and transferred to the correct fields in the target table during the import process. Therefore, the correct answer is C. Transform Map.

The other options are not related to this specific function:

A. Business Service Management Map: This is not a standard term used in the context of data import and transformation in ServiceNow.

B. Data Sources: These define the origin of the data being imported but do not handle the field mapping between Import Set tables and target tables.

D. Schema Map Relationship Builder: This tool visualizes the relationships between tables in the database schema but is not used for mapping fields during data transformation.

For more detailed information, refer to the official ServiceNow documentation on Transform Maps.

Flow Designer variables can store record data and complex data using the following data types:

Integer: A whole number that can be used in mathematical operations.

Array: A collection of items that can be accessed by their index or iterated over using a For each action.

String: Any kind of text, such as email addresses or the text contents of a file.

The ServiceNow platform is designed to create applications that use forms, workflow, and reporting to solve business problems. Forms are used to interact with data stored in tables, workflow is used to automate and orchestrate processes, and reporting is used to visualize and analyze data. The platform does not require low-level programming libraries or multimedia features, as it provides standard tools and technologies for application development.

Application Files are ServiceNow artifacts comprising an application. An application is a group of files and data that work together to provide a service or functionality. An application file is a specific type of file that belongs to an application, such as a table, a script, a form, a business rule, a UI action, etc. Application files define the structure, logic, and interface of the application. An XML export of an application’s table records, XML exports of an application’s Update Set, and CSV files containing data imported into an application are not examples of application files, as they are data formats that can be used to transfer or store information related to an application, but not the application itself. Reference: Application Files

 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

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.

ServiceNow provides several methods to install applications onto an instance, each suited to different scenarios:

Import an Application from an XML File (Option A):

Description: Developers can export an application as an XML file and then import it into another ServiceNow instance.

Use Case: This method is commonly used for moving applications between instances, such as from development to production.

Procedure:

Navigate to "System Applications" > "Applications."

Click on the "Import" button.

Upload the XML file of the application.

The GlideUser object (g_user) is part of the client-side scripting API that provides information about the current user and the user’s preferences. It can be used in Client Scripts and UI Policies to customize the user interface based on the user’s role, language, time zone, etc. The workflow.scratchpad object is only available in Workflow scripts, which are used to automate processes on the platform. The current and previous objects are only available in server-side scripts, such as Business Rules and Script Includes. The GlideSystem object (gs) is also a server-side object that provides methods for logging, debugging, date and time calculations, etc.

While record producers are powerful tools for creating records via the Service Catalog, they cannot natively redirect users after submission. Redirection typically requires script hacks or custom widget configurations.

From ServiceNow Docs (Catalog Scripting):

“By default, record producers return the user to the catalog homepage. Redirection requires scripting using producer scripts or custom client logic.”

"The sequence is ROLES first, then condition, then script." - Chuck Tomasi says so at this link: https://www.servicenow.com/community/grc-forum/order-of-execution-of-an-acl/m-p/1311962/highlight/true#M6538

A transform map determines the relationships between fields displaying in an Import Set table and fields in an existing ServiceNow table, such as the Incidents or Users table.

When evaluating Access Controls, ServiceNow searches and evaluates:

From the most specific match to the most generic match. This is the correct answer because ServiceNow follows a top-down approach when evaluating Access Control (ACL) rules, which are used to restrict the access to the data and functionality of the ServiceNow platform based on the user’s roles and conditions. ServiceNow starts with the most specific match, which is the field-level ACL rule, then moves to the table-level ACL rule, and finally to the global or * ACL rule. ServiceNow grants access if any of the ACL rules evaluates to true, and denies access if all of the ACL rules evaluate to false.

The following are not correct descriptions of how ServiceNow searches and evaluates Access Controls:

Only for matches on the current table. This is not correct because ServiceNow does not only look for matches on the current table, but also on the parent tables and the global or * table. For example, if there is no ACL rule for the incident table, ServiceNow will look for an ACL rule for the task table, which is the parent table of the incident table, and then for the global or * table, which is the parent table of all tables.

Only for matches on the current field. This is not correct because ServiceNow does not only look for matches on the current field, but also on the table that contains the field and the global or * table. For example, if there is no ACL rule for the short_description field on the incident table, ServiceNow will look for an ACL rule for the incident table, and then for the global or * table.

From the most generic match to the most specific match. This is not correct because ServiceNow does not follow a bottom-up approach when evaluating Access Controls, but a top-down approach, as explained above. References: Access Control Rules, ACL Evaluation Order

Checkbox tooltip: "Show this module when the user has the specified roles. Otherwise the user must have the roles specified by both the application menu and the module."

The following is true for the Override application menu roles configuration option when configuring a module:

Users with the module role but without access to the application menu access the module. This is true because the Override application menu roles option allows users to bypass the application menu role requirement and access the module directly if they have the module role. For example, if a module has the itil role and the Override application menu roles option enabled, and the application menu has the admin role, then a user who has the itil role but not the admin role can still access the module.

The following are not true for the Override application menu roles configuration option when configuring a module:

Self-Service users can access the module even though they do not have roles. This is false because the Override application menu roles option does not grant access to the module to users who do not have any roles. Self-Service users are users who do not have any roles assigned to them and can only access the Self-Service portal and the Knowledge Base. To access the module, users need to have at least the module role.

Admin is given access to the module even if Access Controls would ordinarily prevent access. This is false because the Override application menu roles option does not override the Access Control (ACL) rules that apply to the module. Access Control rules are used to restrict the access to the data and functionality of the ServiceNow platform based on the user’s roles and conditions. Admin is a role

In ServiceNow, the gs object provides a range of methods for logging messages on the server side. However, the availability of these methods can vary depending on whether the application is global or scoped.

gs.info(): This method is available in scoped applications and is used to log informational messages to the system log. It provides a way to record general information during script execution.

Options A (gs.log()), B (gs.print()), and D (gs.debugLog()) are not available in scoped applications. These methods are either restricted to global applications or do not exist in the ServiceNow API.

For more detailed information, refer to the official ServiceNow documentation on server-side scripting:

The server-side API debug log method available for scoped applications is gs.info(). This method logs informational messages that describe the progress of the application. Older methods such as gs.print() and gs.log() are not available in scoped applications. The gs.debuglog() method does not exist. The gs.info(), gs.warn(), gs.error(), and gs.debug() methods work in both scoped applications and global, and are therefore more versatile going forward in future versions.

Table Extension in ServiceNow:Extending a table in ServiceNow means creating a child table based on a parent table. The child table inherits the fields, configurations, and functionality of the parent table.

What is Inherited:

Fields: All fields from the parent table are available in the child table.

Functionality: The child table benefits from any business logic or workflows defined for the parent table.

Access Controls: The child table respects the Access Control rules defined for the parent table unless explicitly overridden.

Why Other Options Are Incorrect:

Option B: This is incorrect because the new table does inherit fields from the parent table.

Option C: This is incorrect because you do not need to script or configure behaviors from scratch; they are inherited.

Option D: This is incorrect because Access Controls are not ignored; they still apply and can be extended or modified for the child table.

ServiceNow Developer Documentation on Table Inheritance​.

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.

ServiceNow provides several methods for developers to publish and share applications once they are ready for distribution. The supported methods include:

Publish to an application repository: This method allows developers to publish their applications to a centralized repository, enabling easy distribution and installation across multiple ServiceNow instances. The application repository serves as a hub where applications can be stored and accessed by other instances.

Publish to the ServiceNow Store: Developers can submit their applications to the ServiceNow Store, a marketplace where applications are reviewed, certified, and made available to all ServiceNow customers. Publishing to the Store involves a certification process to ensure the application meets ServiceNow's standards.

Publish to an update set: An update set is a container for capturing configuration changes in ServiceNow. Developers can publish applications to an update set, which can then be moved between instances, allowing for the transfer of application configurations and customizations.

Options A (Publish to a spreadsheet), D (Publish to a local USB device), and F (Publish to a local drive) are not supported methods for publishing applications in ServiceNow. These options do not align with the platform's mechanisms for application distribution and deployment.

In ServiceNow, the "Allow access to this table via web services" option within the Application Access settings determines whether the table can be accessed through web service protocols, such as REST and SOAP. When this option is selected, it permits the table to be accessible via web services; however, it does not override existing permissions. The user or system making the web service request must still have the appropriate permissions (such as roles and access controls) to perform operations on the table's records.

Option A: Incorrect. If the "Allow access to this table via web services" option is not selected, the table is not accessible via web services, regardless of user permissions.

Option B: Correct. Enabling this option allows the table to be accessed via web services, but the user must have the correct permissions to access the table's records.

Option C: Incorrect. This option applies to all web service protocols, including both SOAP and REST.

Option D: Incorrect. This option controls overall web service access to the table; specific operations (create, read, update, delete) are governed by user permissions and access controls.

A possible reason to build a custom app is to fulfill a specific use case on internal processes. For example, you may want to digitize a manual process that is not covered by an existing ServiceNow solution, such as managing inventory, tracking expenses, or scheduling events. Building a custom app on the Now Platform can help you automate workflows, improve data quality, and provide better user experiences. The other options are not valid reasons to build a custom app. To avoid using a code repository like GitHub or GitLab is not a reason to build a custom app, as you can still use source control integration with your custom app development. To create a custom integration for a 3rd party system is not a reason to build a custom app, as you can use integration tools such as IntegrationHub or REST APIs to connect with external systems without creating an app. To replace ServiceNow base tables is not a reason to build a custom app, as it is not recommended to modify or delete base tables that are essential for ServiceNow functionality.
