Question: In a 3GPP network, what is the primary purpose of the periodic consistency check performed by the administration function in the 3GMS or related nodes?
Option 1: To synchronize software updates across all network nodes.
Option 2: To monitor real-time traffic for Quality of Service (QoS) optimization.
Option 3: To detect and prevent potential security breaches from within the network.
Option 4: To ensure target identities in intercept orders are consistently updated across all relevant nodes against a reference database.
Explanation: The periodic consistency check verifies that the target list of identities, as per lawful intercept orders stored in the Administration Function's database, matches the information held in all involved network nodes, ensuring data integrity and accuracy for lawful interception purposes.
