Question: Upon successful deletion of an Individual Member UE Selection Assistance Subscription, what HTTP status code does the Network Exposure Function (NEF) respond with to the Application Function (AF)?
Option 1: HTTP "200 OK" with the deleted resource details
Option 2: HTTP "202 Accepted" for asynchronous processing
Option 3: HTTP "204 No Content"
Option 4: HTTP "301 Moved Permanently" with a new resource location
Explanation: When the NEF successfully processes the deletion request, it indicates the request has been fulfilled with no additional content to return, aligning with the HTTP "204 No Content" status code definition. This response informs the AF of the operation's success without providing a response body, as there's no need for additional information post-deletion.
