Question: In which of the following scenarios would an Application Enablement Function (AEF) typically execute the procedure to obtain service API access control policy from the CAPIF core function?
Option 1: When the AEF already has the latest policy for performing access control on a specific service API.
Option 2: During initial setup of the AEF within a PLMN (Public Land Mobile Network) trust domain.
Option 3: When the policy for performing access control on a service API is unavailable at the AEF, regardless of its location.
Option 4: Exclusively when the AEF operates outside of any defined trust domain.
Explanation: The correct answer is Option 3 because the AEF executes this procedure specifically when it needs to obtain a policy due to its unavailability for performing access control on service API invocations, regardless of the AEF's location within or outside a trust domain.
