Question: What is the primary purpose of the X3 interface in the context of Lawful Interception, as per 3GPP security standards?
Option 1: To facilitate communication between the Law Enforcement Agency (LEA) and the Network Operator for administrative purposes.
Option 2: To transport intercepted Communication Content (CC) from the interception point to the Mediation Function/Delivery Function (MF/DF).
Option 3: To enable the configuration of interception targets within the network by the LEA.
Option 4: To provide real-time network performance data to support lawful interception activities.
Explanation: The correct answer, Option 2, highlights the X3 interface's role in transporting intercepted Communication Content (CC) from where it is intercepted to the Mediation Function/Delivery Function (MF/DF), which is crucial for lawful interception processes. This aligns with standard practices in telecom security, where such interfaces are defined for the secure and standardized transfer of intercepted data. The other options, while potentially related to lawful interception, do not accurately describe the primary purpose of the X3 interface as outlined in the context of 3GPP security standards.
