Question: Upon successful deletion of an Individual ECS Address Configuration Information resource, what type of HTTP response message is sent by the V-NEF to the Application Function (AF)?
Option 1: HTTP "200 OK" with the deleted resource details
Option 2: HTTP "204 No Content"
Option 3: HTTP "202 Accepted" with a promise to delete asynchronously
Option 4: HTTP "301 Moved Permanently" redirecting to a new resource
Explanation: When the V-NEF successfully deletes the "Individual ECS Address Configuration Information" resource (either after receiving a successful response from the V-UDR or after successful local handling), it responds to the AF with an HTTP "204 No Content" message. This type of response indicates that the server has fulfilled the request but does not need to return an entity-body, which is appropriate for deletion operations where no further content needs to be returned to the client.
