Question: In Mission Critical Data (MCData) communications, how does the File Distribution (FD) function of the MCData server typically distribute downlink file data to multiple recipients when utilizing efficient network resources?
Option 1: Via IP broadcast transmission using a specific reference point for efficient distribution.
Option 2: By sequential IP unicast transmissions to each recipient for personalized delivery.
Option 3: Through SMS (Short Message Service) for reliability and reach in message dissemination.
Option 4: Using multicast downlink transport for efficient group data dissemination.
Explanation: The correct answer is Option 4 because the FD function efficiently distributes downlink file data to multiple recipients through multicast downlink transport, reducing network load compared to individual unicast transmissions.
