Question: In the context of WebRTC Interworking for Lawful Interception (LI), what is the primary function of the WebRTC Web Server Function (WWSF) in relation to the Delivery Function (DF) and Law Enforcement Monitoring Facility (LEMF)?
Option 1: To authenticate user identities and transmit them to the LEMF via the DF.
Option 2: To provide a time-stamped authentication event for targets accessing WebRTC services.
Option 3: To manage Quality of Service (QoS) for WebRTC traffic intercepted by the LI system.
Option 4: To copy and transmit the target's IP address and port, as seen by the WWSF, to the LEMF via the DF.
Explanation: The correct answer is Option 4 because the WebRTC Web Server Function (WWSF) acts as an Intercept Control Element that copies and transmits the IP address and port used by the target to the Law Enforcement Monitoring Facility (LEMF) via the Delivery Function (DF), facilitating lawful interception in WebRTC environments.
