Question: What is the primary purpose of defining supplementary options in the handover interface specification for Lawful Interception (LI) in telecom networks?
Option 1: To accommodate variations in national requirements, national law, and laws applicable to specific Law Enforcement Agencies (LEAs).
Option 2: To enhance the security features for User Equipment (UE) during inter-network handovers.
Option 3: To simplify the implementation of mandatory requirements across all networks.
Option 4: To reduce the complexity of signaling protocols during handover procedures.
Explanation: The correct answer reflects the need for flexibility in the handover interface specification to conform with diverse legal and national requirements that may vary significantly between different regions or LEAs, ensuring effective and legal implementation of Lawful Interception across various jurisdictions.
