Question: What is the primary purpose of the MCData-8 reference point in a Mission Critical Data (MCData) architecture?
Option 1: To facilitate direct communication between User Equipment (UE) for group conversations.
Option 2: To enable the MCData server to retrieve real-time location information from the network.
Option 3: To allow the MCData server to manage and access the MCData message store, including creating user folders and storing communication history.
Option 4: To establish a backup link between the MCData server and external services for emergency situations.
Explanation: The correct answer is Option 3 because the MCData-8 reference point is specifically defined for interactions between the MCData server and the MCData message store. This interaction is crucial for managing data, such as creating folders for individual users and storing a history of communications, which are essential functions for mission-critical data services that require reliability and traceability.
