What action does the User Update Rules usually perform?

User Update Rules primarily function to respond to user profile change requests. When users or administrators submit requests to update specific attributes or information within a user profile, the User Update Rules come into play, facilitating those modifications based on predefined criteria and business logic.

This functionality ensures that the correct processes are followed when handling changes, which could include validating the submitted information, ensuring compliance with policies, and updating the system accordingly. By responding to change requests, these rules allow for greater control over user data while maintaining an organized and efficient system for managing user profiles.

The other actions suggested—such as automatically updating all profiles, ignoring changes, or only updating attributes upon request—do not align with the intended purpose of User Update Rules, as they are specifically designed to manage and respond to requests rather than blanket updates or inactivity regarding profile changes.
