ServiceNow Updated CAD Exam Questions and Answers by zaid

In ServiceNow, to include data from another table within a form, the Reference field type is utilized. A Reference field creates a relationship between the current table and another table by storing a reference to a record in the target table. This allows users to select a record from the referenced table and display related information seamlessly within the form.

A. Use the Date field type: This is incorrect. The Date field type is designed to store date values and does not facilitate referencing records from other tables.

B. Use the Phone Number field type: This is incorrect. The Phone Number field type is intended for storing phone number data and does not support referencing other table records.

C. Use the String field type: This is incorrect. The String field type stores text data and does not inherently provide functionality to reference records from other tables.

D. Use the Reference field type: This is correct. The Reference field type is specifically designed to create a link to a record in another table, enabling the incorporation of related data into the form.

For example, in the Incident table, the "Caller" field is a reference to the User [sys_user] table, allowing the selection of a user as the caller for the incident. This setup ensures data consistency and leverages existing records without data duplication.

For more detailed information, refer to the official ServiceNow documentation on Reference Fields.

Search branch and merge branches are available features in Studio. Search branch allows you to search for a specific branch name or ID in your Git repository. Merge branches allows you to merge changes from one branch to another, resolving any conflicts that may arise. Push to external source control and push to update set are not available features in Studio. Push to external source control is a feature of Source Control Integration, which is a separate application from Studio. Push to update set is a feature of Update Set Previewer, which is also a separate application from Studio. Reference: Studio, Source Control Integration, Update Set Previewer

 Extending an existing table such as the Task table when creating a new application has several benefits, such as:

You can repurpose existing fields by simply changing the label. For example, you can change the Short description field to Summary or Title for your new table.

You can use existing fields with no modifications. For example, you can use the Assigned to, Priority, and State fields for your new table without changing anything.

Existing logic from the parent table will be automatically applied to the new table. For example, you can inherit the Business Rules, Client Scripts, and UI Policies from the Task table for your new table.

The only option that is not true is d) All of the parent table records are copied to the new table. Extending a table does not copy any records from the parent table to the new table. It only creates a new table that inherits the fields and logic from the parent table.
