Question: Upon successful creation of a Member UE Selection Assistance Subscription, what does the Network Exposure Function (NEF) include in its response to the Application Function (AF), in addition to a '201 Created' status code?
Option 1: A 'Location' header field with the URI of the created resource and a response body with the created subscription representation within the MemUeSelectAssistSubsc data structure.
Option 2: Only a 'Location' header field pointing to the NEF's API root, without any specific subscription details.
Option 3: A list of all available 5GC Network Functions (NFs) that the NEF interacted with for this subscription.
Option 4: An empty response body with just the '201 Created' status code, as per HTTP protocol defaults.
Explanation: This is correct because, upon successful subscription creation, the NEF responds with a '201 Created' status code, which is standard for indicating successful resource creation. Additionally, it includes a 'Location' header field containing the URI of the newly created resource, allowing the AF to easily identify and manage the subscription. The response body also contains a representation of the created subscription within the specified data structure (MemUeSelectAssistSubsc), providing the AF with detailed information about the subscription.
