Question: In a 5G network, when the NEF (Network Exposure Function) notifies an Application Function (AF) about 5G LAN parameter provisioning events and the 'GMEC' feature is supported, how does the AF acknowledge successful reception of this notification?
Option 1: By responding with an HTTP '200 OK' status code and a detailed acknowledgement message.
Option 2: By responding with an HTTP '204 No Content' status code.
Option 3: By initiating a new HTTP GET request to confirm the update.
Option 4: By sending a separate acknowledgement message over a different protocol (e.g., SMS).
Explanation: When the NEF successfully notifies an AF about provisioning events for 5G LAN parameters, and the 'GMEC' feature is enabled, the AF's response to acknowledge this notification, as per standard practices for such API interactions, would be to send a status code indicating the request was processed without needing to return any content. An HTTP '204 No Content' status code is specifically used in such scenarios, signifying successful processing without providing a response body, which aligns with the described interaction between NEF and AF in this context.
