Question: Upon successful update of an Individual Media Streaming Event Exposure Subscription, what HTTP status code(s) may the Network Exposure Function (NEF) return to the Application Function (AF) in the Nnef_MSEventExposure_Subscribe response message?
Option 1: Only "201 Created"
Option 2: Either "200 OK" with AfEventExposureSubsc data structure or "204 No Content"
Option 3: Both "200 OK" without AfEventExposureSubsc data structure and "500 Internal Server Error"
Option 4: Only "202 Accepted"
Explanation: According to the procedure for updating a Media Streaming Event Exposure Subscription, upon receiving a successful response from the data collection AF, the NEF returns a Nnef_MSEventExposure_Subscribe response message with either an HTTP "200 OK" status code (including the AfEventExposureSubsc data structure) or a “204 No Content” status code. This indicates that both options are valid responses for a successful update, highlighting the flexibility in response handling based on the specific outcome of the subscription update process.
