Event based certification can be performed using which of the following?

Event-based certification is a process that allows organizations to validate user entitlements and access rights based on specific events triggered within the system, such as changes in user roles, new account creations, or modifications in permissions. This type of certification helps ensure that the access being granted is still appropriate and complies with security policies.

The entitlement update rule specifically caters to changes in user entitlements. When certain events occur, such as when an entitlement is added or removed from a user, the entitlement update rule can trigger a certification process to review the new access rights that have been granted or revoked. This makes it the most suitable choice for event-based certification as it directly engages with the changes in user entitlements and initiates the necessary review and approval steps to ensure compliance with access control policies.

Other options would either not be specifically designed for event-based certification or relate to user updates that may not involve entitlement changes directly, which diminishes their relevance in this context. Hence, the entitlement update rule stands out as the correct answer for performing event-based certifications in a robust identity governance framework.
