Question: What is the primary purpose of the MCData-11 reference point in a Mission Critical Data (MCData) architecture?
Option 1: To facilitate direct communication between User Equipment (UE) for group messaging
Option 2: To enable the MCData message store to send notification messages to subscribed Message Notification Clients
Option 3: To manage Quality of Service (QoS) parameters for MCData transmissions
Option 4: To handle authentication procedures for MCData services
Explanation: The correct answer, Option 2, accurately reflects the role of the MCData-11 reference point. This reference point is crucial for notifying subscribed clients about new or updated messages, ensuring timely delivery of mission-critical information. The other options are incorrect because they describe functions not associated with the MCData-11 reference point: direct UE communication is more related to peer-to-peer services, managing QoS parameters is a function typically associated with network resource management, and handling authentication procedures involves security aspects not specifically tied to this reference point.
