Question: What is the primary purpose of AF Notifications in the context of Network Exposure Function (NEF) in a 5G System?
Option 1: To request additional service parameters from the Application Function (AF)
Option 2: For the NEF to discover available AF services
Option 3: To establish a secure connection between the NEF and AF
Option 4: To send Service Parameter Authorization Updates and/or notify the AF of outcomes related to service parameter provisioning
Explanation: This is correct because AF Notifications, as utilized by the Network Exposure Function (NEF), serve two key purposes: firstly, to update the Application Function (AF) regarding changes in Service Parameter Authorization (such as revoking an authorization), and secondly, to notify the AF about the outcomes of service parameter provisioning invocations that the AF has subscribed to. This ensures the AF remains informed and can adjust its operations accordingly, highlighting the importance of these notifications in maintaining dynamic network management and security.
