Question: In 3GPP Lawful Interception (LI), what is a key characteristic of the file content in method A compared to method B?
Option 1: Method A allows multiple targets per file, while Method B is limited to one target per file.
Option 2: The file format differs between Method A (binary) and Method B (text-based).
Option 3: Method A requires encryption, whereas Method B does not.
Option 4: Method A relates to only one target, while Method B may relate to any number of targets.
Explanation: This question assesses understanding of the distinctions between file transfer methods in the context of Lawful Interception as per 3GPP standards. The correct answer, Option 4, highlights that a fundamental difference between Method A and Method B lies in the number of targets each method's file content can relate to. Specifically, Method A is restricted to one target, whereas Method B offers flexibility by potentially including intercept records for multiple targets, all sent to a particular Law Enforcement Monitoring Facility (LEMF) address. This distinction is crucial for implementing and managing lawful interception effectively in telecommunications networks.
