Approval before elevation is implemented by requiring approval to activate the PIM role. Automatic removal after a fixed active period is controlled by the activation maximum duration. Expiring active or eligible assignments governs the assignment lifecycle, not the duration of each activation session. Requiring justification can improve audit quality, but it does not ensure that another administrator evaluates the request or that access ends after the configured active window. 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.
