Question: On which interfaces are Intercept Related Information (Events) sent during attach/tunnel activation, according to 3GPP security standards for Lawful Interception?
Option 1: S1-U and X2
Option 2: S5/S8 and S11
Option 3: s2a and s2c
Option 4: S6a and Gx
Explanation: In the context of Lawful Interception as per 3GPP security standards, Intercept Related Information (Events) are specifically sent on interfaces s2a and s2c during events like attach/tunnel activation. This is crucial for facilitating lawful interception in telecommunications networks, ensuring that relevant information is provided to authorized parties at key points of network activity. The correct interfaces, s2a and s2c, are directly involved in the signaling and management of user plane tunnels in EPS (Evolved Packet System) and related architectures, making them the appropriate channels for such informational exchanges.
