Question: What is the primary purpose of the N4 Report procedure in the 5G System (5GS) architecture?
Option 1: To establish a new N4 session between the UPF and SMF.
Option 2: To report information not related to a specific N4 session, such as user plane path failure or clock drift.
Option 3: To request configuration updates from the SMF for one or more external working domains.
Option 4: To initiate a network instance creation procedure between the UPF and SMF.
Explanation: The N4 Report procedure is used by the UPF to report information to the SMF that is not related to a specific N4 session, such as user plane path failure or clock drift. This allows the SMF to take necessary actions based on the reported information, ensuring proper functioning of the 5GS network.
