After configuring domain security policies, what task must you run to ensure the most recent...

Whenever changes are made to domain security policies, they remain in a pending state until you explicitly activate them by running the:

Activate Pending Security Policy Changes task.

This ensures that all updates to permissions are applied across the tenant for real-time enforcement.

A. Activate Previous Security Timestamp reverts to a prior configuration.

B. Activate All Pending Authentication Policy Changes is only for authentication rules.

D. Activate Metadata Schedule applies to metadata changes, not security.
