Which rules can be triggered based on an event?

The User Update Rule is designed specifically to be triggered by events associated with user changes or updates. This means any alterations or actions taken on a user's account, such as modifications to user attributes or changes in user status, can initiate this rule. This allows organizations to manage and respond dynamically to updates in user information by enforcing particular policies or conditions relevant to the changed attributes.

In contrast, other types of rules, such as Technical Rules, SCAN Rules, and Entitlement Rules, serve different purposes. Technical Rules often focus on system-level operations and policies rather than specific user events. SCAN Rules typically relate to the auditing and scanning of systems for compliance rather than responding directly to user actions. Entitlement Rules are usually centered around the specific permissions or access rights assigned to users, influencing access control but not directly reacting to user-triggered events.

Thus, the emphasis on user events and changes is what makes the User Update Rule the correct answer in this context.
