Question: In 3GPP Lawful Interception, which two identifiers comprise the Communication Identifier (CID) for correlating Intercept Related Information (IRI) with Content of Communication (CC)?
Option 1: Network IDentifier (NID) and Communication Identity Number (CIN)
Option 2: Lawful Interception IDentifier (LIID) and CC Link IDentifier (CCLID)
Option 3: Intercepting Node ID and Lawful Interception IDentifier (LIID)
Option 4: Correlation Number and HI2 Interface Identifier
Explanation: The correct answer is Option 1 because, according to the specifications for correlating CC and IRI in the context of Lawful Interception, the Communication Identifier (CID) is specifically composed of two key identifiers: the Network IDentifier (NID) and the Communication Identity Number (CIN).
