Question: What information does the AMF store in the UDM when N26 is deployed, depending on the operator's configuration?
Option 1: DNN and SMF+PGW-C FQDN for S5/S8 interface
Option 2: UE's IP address and APN
Option 3: PDN GW's IP address and TEID
Option 4: eNodeB's ID and cell ID
Explanation: The AMF stores the DNN (Data Network Name) and SMF+PGW-C FQDN (Fully Qualified Domain Name) for S5/S8 interface in the UDM using Nudm_UECM_Update service operation when N26 is deployed, as per the operator's configuration. This information is crucial for EPS interworking and allows the AMF to retrieve the necessary data for session management.
