ServiceNow CAD - Certified Application Developer - ServiceNow

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.

Application scope is a foundational concept in ServiceNow application development. ServiceNow documentation describes application scoping as a protection mechanism that identifies and restricts access to an application’s files and data. In practice, scope defines an isolation boundary around an application’s artifacts, such as tables, scripts, UI components, and other resources. This boundary helps prevent unintended interference between applications and reduces the risk of naming collisions or cross-application impacts. The scope model also works together with Application Access settings, which allow administrators to specify what parts of an application are accessible to other applications. By default, scoped applications are designed to keep resources private unless explicitly shared through access settings or cross-scope privileges. Because of this, the primary purpose of scope is not backups or UI design control, and it is explicitly not meant to enable unrestricted updates across applications. Instead, scope exists to define and enforce boundaries so that an application’s resources remain isolated and protected unless intentionally exposed.

The statement that is true for this script fragment is that the method returns true if the currently logged in user has the x_my_app_user role or the admin role. The g_user.hasRole() method is a client-side method that checks whether the current user has a specified role or set of roles. If no role is specified, it returns true if the user has any role. If one or more roles are specified, it returns true if the user has any one of the specified roles. However, this method always returns true if the user has the admin role, regardless of the role parameter. Therefore, in this case, the method returns true if the user has either the x_my_app_user role or the admin role. Reference: User Object Cheat Sheet, Checking user permissions

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.

You must script and configure all required behaviors Provided link has this statement: Extending an existing ServiceNow table means the new table inherits the parent table's columns as well as its business logic.

The following statements apply when extending an existing table:

The parent table’s Access Controls are evaluated when determining access to the new table’s records and fields. This is true because Access Control (ACL) rules are inherited from the parent table to the child table, unless the child table has its own ACL rules that override the parent table’s rules. ACL rules are used to restrict the access to the data and functionality of the ServiceNow platform based on the user’s roles and conditions.

The new table inherits the functionality built into the parent table. This is true because the new table inherits the business logic and the relationships from the parent table, such as Business Rules, Script Includes, UI Actions, UI Policies, and Reference Fields. Business logic and relationships are used to define the behavior and the structure of the data on the ServiceNow platform.

The new table inherits all of the fields from the parent table. This is true because the new table inherits the columns and the attributes from the parent table, such as Field Name, Data Type, Default Value, and Mandatory. Columns and attributes are used to define the properties and the characteristics of the data on the ServiceNow platform.

The following statement does not apply when extending an existing table:

You must script and configure all required behaviors. This is false because you do not have to script and configure all required behaviors when extending an existing table, as some of the behaviors are already inherited from the parent table, as explained above. However, you can script and configure additional or customized behaviors for the new table, such as adding new fields, creating new Business Rules, or modifying existing UI Actions. References: Table Extension, Access Control Rules

In the Automated Test Framework (ATF) of ServiceNow, the "Impersonate" test step is used to simulate actions as a specific user. This is crucial for testing functionalities that depend on user roles, permissions, or specific user contexts.

Key Points:

Purpose: The "Impersonate" step allows the test to execute subsequent steps as if performed by the specified user, ensuring that role-based permissions and access controls are accurately tested.

Usage: To add an "Impersonate" step:

Open your test in ATF.

Click on "Add Test Step."

Select "Impersonate User."

Choose the user you want to impersonate for the test.

Considerations: Ensure that the user being impersonated has the necessary roles and permissions for the actions being tested. Additionally, be aware that impersonation affects both server-side and client-side operations during the test.

A Display Business Rule has access to the current, g_scratchpad, and GlideSystem objects, but not the previous object. The previous object is only available to Before Business Rules4. References: Business Rule API

The Form Designer is a graphical interface for creating and customizing forms. The following statements are true for the Form Designer:

To add a field to the form layout, drag the field from the Fields tab to the desired destination on the form. This will add the field to the form view without changing the table definition.

To create a new field on a form’s table, drag the appropriate data type from the Field Types tab to the form and then configure the new field. This will create a new column on the table and add the field to the form view.

To remove a field from the form layout, hover over the field to enable the Action buttons, and select the Delete (X) button. This will remove the field from the form view but not from the table definition.

The following statement is false for the Form Designer:

To add a section to the form layout, drag it from the Field Types tab to the desired destination on the form. This is incorrect because sections are not available in the Field Types tab. To add a section, click the Add Section button on the toolbar or right-click on the form and select Add Section. References: Introduction to App Engine Studio for Developers, ServiceNow Studio Overview, Form Designer
