Question: Which interface is utilized by the API invoker to trigger the offboarding procedure from the Common API Framework (CAPIF), making it no longer a recognized user?
Option 1: CAPIF-2, through a direct network request
Option 2: CAPIF-1 or CAPIF-1e, as initiated by the API invoker
Option 3: A dedicated offboarding portal (COP)
Option 4: Via the mobile network's SS7 signaling network
Explanation: The correct answer is Option 2 because, according to the defined procedure for offboarding from the CAPIF, the process is specifically triggered by the API invoker using either the CAPIF-1 or CAPIF-1e interface. This highlights the importance of these interfaces in managing user recognition and access within the Common API Framework, ensuring secure and controlled offboarding processes.
