Question: In a 5G network, where is the Globally Unique AMF Identifier (GUAMI) temporarily and conditionally stored?
Option 1: Only in the User Data Management (UDM) entity
Option 2: Exclusively within the Serving and Session Management Function (SMF)
Option 3: Solely in the Access and Mobility Management Function (AMF) of the serving network slice
Option 4: Across the User Data Management (UDM), Session Management Function (SMF), and Access and Mobility Management Function (AMF)
Explanation: The GUAMI is a unique identifier for an AMF in a 5G network, crucial for managing subscriber sessions efficiently. Given its role, it's logical that the GUAMI would be stored in entities directly involved with session management and user data. Thus, it's temporarily and conditionally stored across the UDM (for user data), SMF (for session management), and AMF (the serving network component itself), ensuring seamless and coordinated service provision.
