Question: What characterizes the transmission process when a Mission Critical Data (MCData) Short Data Service (SDS) message is sent between clients in a telecom network?
Option 1: It requires a manual acknowledgement from the receiving MCData client before data transfer.
Option 2: It involves a request/grant procedure initiated by the sending MCData client for bandwidth allocation.
Option 3: It relies on pre-established sessions that must be renewed for each SDS message transmission.
Option 4: It transfers data without any request/grant procedure or explicit actions from the receiving MCData client.
Explanation: This correct answer reflects the nature of MCData SDS transmissions, highlighting their design for efficient, low-latency communication critical in mission-critical scenarios. By not requiring a request/grant procedure or any action from the receiving end, these transmissions can occur swiftly, which is paramount for applications like emergency services or critical communications where every second counts. This characteristic underscores the telecom network's ability to support time-sensitive, reliable data exchanges.
