Question: For 3GPP H(e)NBs, how is the intercepted Content of Communications (CC) delivered to the Lawful Interception (LI) system?
Option 1: Through encryption of original packets with a special LI key
Option 2: By modifying the packet headers to redirect to the LI system
Option 3: Using a separate, dedicated network interface for LI traffic only
Option 4: Based on duplication of packets without modification
Explanation: This is correct because the specified method for delivering intercepted content in the context of 3GPP H(e)NBs involves creating an exact copy of the packets, ensuring the original communication remains unaffected and the intercepted data is a faithful replica. This approach maintains integrity and avoids any potential interference with the legitimate network traffic or the target's communication stream.
