Question: When an Application Function (AF) requests the deletion of a Data Reporting Provisioning Session from the Network Exposure Function (NEF), which HTTP method is used and what is the expected response status code from the NEF?
Option 1: HTTP PUT, with a "200 OK" status code
Option 2: HTTP DELETE, with a "404 Not Found" status code
Option 3: HTTP PATCH, with a "202 Accepted" status code
Option 4: HTTP DELETE, with a "204 No Content" status code
Explanation: The correct answer is Option 4 because when an AF wants to delete an existing Data Reporting Provisioning Session, it sends a request using the HTTP DELETE method to the NEF. Upon successful deletion of the targeted resource, the NEF responds with an HTTP "204 No Content" status code, indicating the resource has been successfully deleted without returning any content in the response body. This aligns with standard HTTP protocol usage for resource deletion.
