ServiceNow Exam CAD Topic 9 Question 89 Discussion

Comprehensive and Detailed Step-by-Step

Reference Field Type:

The Reference field type is used to create a relationship between two tables. It allows you to select and display records from another table directly on a form.

For example, adding a 'Caller' field to an Incident form enables you to query and select records from the sys_user table.

Why Other Options Are Incorrect:

Option B (Phone Number field type): This is used for storing phone numbers, not for querying records from another table.

Option C (String field type): While this stores plain text, it does not allow querying or establishing relationships with other tables.

Option D (Date field type): This is used for date or time values, not for referencing another table.
