Question: Upon successful creation of an AM policy event subscription via an HTTP PUT request, what response does the Network Exposure Function (NEF) send to the Application Function (AF), including the created resource and potentially immediate reporting values?
Option 1: HTTP "200 OK" with AmEventsSubscRespData and a Location header
Option 2: HTTP "201 Created" with AmEventsSubscRespData but no Location header
Option 3: HTTP "201 Created" with AmEventsSubscRespData, including the created resource, and a Location header containing the URI of the individual subscription resource
Option 4: HTTP "204 No Content" with immediate reporting values only
Explanation: When an AF successfully creates a new AM policy event subscription, the NEF responds with an HTTP "201 Created" status code. This response includes the AmEventsSubscRespData structure, which contains details of the newly created "AM Policy Events Subscription" resource. Additionally, if immediate reporting was requested for the subscribed events, the response will include the currently available values received from the Policy Control Function (PCF). The Location header field in the response provides the URI of the created individual subscription resource, facilitating future reference or updates by the AF. This comprehensive response ensures the AF is fully informed about the new subscription and its immediate state.
