Question: In a 5G network supporting the "5MBS2" feature, what is the expected response from the Network Exposure Function (NEF) to an authorized Application Function (AF) after successfully provisioning MBS Session Assistance information for multicast MBS sessions via the UDM?
Option 1: HTTP "200 OK" status code with an empty response body
Option 2: HTTP "201 Created" status code without any Location header field
Option 3: HTTP "201 Created" status code including a Location header field containing the URI of the created resource, and the response body with the MbsPpData data structure
Option 4: HTTP "404 Not Found" status code indicating unsuccessful provisioning
Explanation: Upon successful provisioning of MBS Session Assistance information for multicast MBS sessions through the UDM, the NEF's response to the AF includes a confirmation of the creation of a new resource. This is best indicated by an HTTP "201 Created" status code. Additionally, providing a Location header field with the URI of the created resource and including the MbsPpData data structure in the response body ensures the AF has all necessary details about the newly created "Individual MBS Parameters Provisioning" resource, aligning with standard RESTful API practices for resource creation.
