Question: In a 5G System, when an Application Function (AF) requests deallocation of previously allocated MBS TMGI(s) via the NEF using HTTP POST, what is the expected response from the NEF to the AF upon successful deallocation confirmation from the MB-SMF?
Option 1: HTTP "200 OK" status code with a detailed success message
Option 2: HTTP "204 No Content" status code without a response body
Option 3: HTTP "201 Created" status code indicating a new resource was created
Option 4: HTTP "503 Service Unavailable" status code due to deallocation processing
Explanation: Upon successful deallocation of MBS TMGI(s) as confirmed by the MB-SMF, the NEF responds to the AF with a response indicating success without new content. An HTTP "204 No Content" status code is used for delete/deallocate operations where no further information needs to be conveyed beyond the operation's success.
