Question: In a Lawful Interception (LI) scenario, as per 3GPP security standards, what is the primary purpose of using the correlation number in the ULIC header within the LEMF?
Option 1: To encrypt intercepted data for secure transmission.
Option 2: To prioritize intercepted packets based on sequence numbers.
Option 3: To authenticate the source of intercepted communications.
Option 4: To correlate Communication Content (CC) with Identifying Information (IRI).
Explanation: The correct answer is Option 4 because, in Lawful Interception as outlined by 3GPP security standards, correlating Communication Content (CC) with Identifying Information (IRI) is crucial for linking intercepted communication data with the relevant subscriber or user information, ensuring accurate attribution of intercepted content to the intended target.
