Question: In Mission Critical Data (MCData) services, what is the primary purpose of the remote initiated tear down mechanism for point-to-point IP connectivity?
Option 1: To establish temporary group communications among MCData clients.
Option 2: To enhance security by periodically resetting IP connections.
Option 3: To allow destination MCData clients to reject incoming connections.
Option 4: To enable authorized MCData users to remotely terminate existing point-to-point IP connections.
Explanation: This option correctly reflects the primary purpose of the remote initiated tear down mechanism. It highlights the capability for an authorized user to remotely end (tear down) an already established point-to-point IP connectivity between two MCData clients, ensuring control and potentially enhancing security or resource management in mission-critical communications scenarios.
