Question: What type of information should the 5G system be able to prevent from being shared in private communications among User Equipment (UEs) using 5G LAN-type services?
Option 1: Location Information
Option 2: Service Usage Patterns
Option 3: Network Configuration Details
Option 4: UE's Identifying Information, such as SUPI or MSISDN
Explanation: The correct answer is Option 4 because the 5G system should be able to prevent the sharing of a UE's identifying information (e.g. SUPI, MSISDN) on private communication among UEs using 5G LAN-type service, as per the given text. This ensures that sensitive user identification data remains confidential during private communications over the network.
