Question: What is the primary purpose of the CN Deactivate Trace procedure in the UTRAN Iu interface RANAP signalling?
Option 1: To initiate a new trace session for a specific UE on the Iu connection.
Option 2: To instruct the RNC to terminate an existing trace session, activated via signalling, for a specified trace reference related to a UE's Iu connection.
Option 3: To modify the configuration of an ongoing trace session for enhanced debugging on the RAN side.
Option 4: To request the RNC to send trace data for all UEs connected through the Iu interface.
Explanation: The CN Deactivate Trace procedure is designed to stop a previously started trace session via signalling, targeting the trace reference associated with a UE's Iu connection, involving communication between the Core Network and the Radio Network Controller for reliability.
