Question: In Mission Critical Data (MCData) services, what is the primary purpose of the remotely initiated point-to-point IP connectivity mechanism?
Option 1: To enable group communication among all MCData clients on a network.
Option 2: To facilitate direct communication between an MCData server and its clients.
Option 3: To allow an MCData client to dynamically change its IP address during an active session.
Option 4: To permit an authorized MCData user to remotely establish a dedicated IP connection between two specified MCData clients.
Explanation: This option correctly captures the essence of the remote initiation mechanism for point-to-point IP connectivity in MCData services, as outlined. It highlights the ability of an authorized user to trigger a direct, one-to-one IP connection between two specific MCData clients from a remote location, which is crucial for mission-critical communications that require secure, dedicated channels. The other options do not accurately represent the primary purpose of this mechanism.
