Question: Under what condition can the network include the NSAG information IE in the CONFIGURATION UPDATE COMMAND message when sent over 3GPP access?
Option 1: If the UE has set the NSAG bit to "NSAG not supported" in the 5GMM capability IE of the REGISTRATION REQUEST message.
Option 2: If the UE has set the NSAG bit to "NSAG supported" in the 5GMM capability IE of the REGISTRATION REQUEST message.
Option 3: If the network has previously sent an NSAG information IE in a previous CONFIGURATION UPDATE COMMAND message.
Option 4: If the UE is in a specific geographic location.
Explanation: The correct answer is Option 2 because, according to the specification, the network can include the NSAG information IE in the CONFIGURATION UPDATE COMMAND message only if the UE has indicated its support for NSAG by setting the corresponding bit in the 5GMM capability IE of the REGISTRATION REQUEST message.
