Question: In Mission Critical Data (MCData) communications, what method does an MCData client utilize for a standalone data file download from another MCData client, as per 3GPP specifications?
Option 1: Control Plane with dedicated bearer setup
Option 2: Media Plane for direct file transfer
Option 3: Signaling Radio Bearers (SRBs) for file sharing
Option 4: Circuit Switched (CS) fallback for data download
Explanation: The correct answer is Option 2 because, according to the provided context from 3GPP specifications, the MCData client specifically uses the Media Plane for a standalone data file download. This approach enables direct and efficient file transfer between MCData clients, which is crucial for mission-critical communications where reliability and speed are paramount. The Media Plane’s role in this context highlights its importance in handling user data, such as file transfers, directly without unnecessary protocol overhead.
