Question: In a Mission Critical Data (MCData) scenario, what are the possible ways to cancel an in-progress emergency group state for a group, as per 3GPP specifications?
Option 1: Only through the group SDS in-progress emergency state cancellation procedure.
Option 2: Solely by utilizing the emergency alert cancellation procedure from a related specification.
Option 3: Exclusively via a direct command from the Public Safety Answering Point (PSAP).
Option 4: Through either the group SDS in-progress emergency state cancellation procedure or the emergency alert cancellation procedure specified in another relevant 3GPP specification.
Explanation: This answer is correct because an MCData in-progress emergency group state can be cancelled through two identified procedures: (1) the group SDS in-progress emergency state cancellation procedure, and (2) the emergency alert cancellation procedure from another relevant 3GPP specification. This highlights the flexibility and redundancy built into mission-critical communication protocols for swift response and management of emergency situations.
