Question: Which of the following entities is NOT responsible for generating log files according to lawful interception architecture in 3GPP networks?
Option 1: DF2 (Delivery Function 2)
Option 2: UE (User Equipment)
Option 3: 3G MSC Servers (3G Mobile Switching Center Servers)
Option 4: CSCF (Call Session Control Function)
Explanation: According to the lawful interception architecture in 3GPP networks, log files are generated by specific network entities. User Equipment (UE) is not among these, as it's primarily the end-user's device for accessing network services, and its primary function does not include generating log files for lawful interception purposes at the network level.
