Eligible approvers: Admin1 and Admin3 only; Maximum active duration of the role: 1 day

The answer area indicates that Admin1 and Admin3 are the eligible approvers and that the active AI Administrator role duration is one day. This is consistent with PIM role settings: approvers are explicitly configured for a role activation policy, and maximum active duration controls how long the activated role remains available. Other administrators who are not configured as approvers cannot approve the request merely because they hold unrelated roles. This domain is tested through precise scope control: tenant, subscription, resource, application, and data-plane authorization are not interchangeable. The correct choice applies the smallest identity or governance control that enforces the stated requirement. Options that only add users, create registrations, or provide broad administrator access fail because they do not directly enforce the requested access behavior. The result is a direct exam-style implementation choice: it changes the required security behavior without relying on unrelated monitoring, manual cleanup, or excessive privilege.
