Question: What is the primary purpose of using TPKT in the Lawful Interception delivery interface for conveying LI application messages?
Option 1: To provide message delineation capability over TCP, ensuring proper segmentation and reassembly of LI data records.
Option 2: To negotiate the maximum TPDU size for efficient data transfer between the LEMF and the Law Enforcement Agency (LEA).
Option 3: To establish a secure, encrypted channel for sensitive LI information, complementing TCP's inherent security features.
Option 4: To enable dynamic protocol class switching based on network conditions, as defined in RFC 2126.
Explanation: TPKT is utilized to encapsulate LI application messages, primarily addressing TCP's lack of inherent message delineation capability. This ensures that upper-layer protocols are properly bounded and interpreted at the receiving end, crucial for reliable delivery of Lawful Interception data records.
