Question: In a Mission Critical Data (MCData) service, when upgrading a Group Short Data Service (SDS) communication to an emergency communication, what action is taken by the MCData client in step 2 of the procedure?
Option 1: The MCData client sets the imminent peril indicator.
Option 2: The MCData client adjusts the bearers' priority to a default setting.
Option 3: The MCData client notifies all users of the group about the impending upgrade.
Option 4: The MCData client terminates non-essential data transmissions.
Explanation: In critical communication scenarios, indicating an imminent peril is crucial for prioritizing communications. By setting the imminent peril indicator in step 2, the MCData client ensures that the emergency nature of the communication is recognized by the network, potentially influencing resource allocation and prioritization to facilitate timely and reliable transmission of critical data. This action aligns with the objective of Mission Critical Data services to provide swift and dependable communications under urgent conditions.
