Question: What action will the Access and Mobility Management Function (AMF) take if it fails to confirm the Subscriber Permanent Identifier (SUPI) from the User Equipment (UE) or the home network?
Option 1: The AMF will reallocate a new 5G-Globally Unique Temporary Identifier (5G-GUTI) to the UE.
Option 2: The AMF will trigger primary authentication using the SUCI.
Option 3: The AMF will deny service to the UE.
Option 4: The AMF will assign a new SUPI to the UE.
Explanation: The AMF is responsible for confirming the SUPI from the UE and the home network. If this confirmation fails, the AMF will take action to protect the security of the network by denying service to the UE. This ensures that only authorized UEs with valid SUPIs can access the network.
