Question: What happens to a User's Functional Alias to Group Bindings after an MC (Mission Critical) Service Log-off in a Mission Critical Services Architecture?
Option 1: The bindings are retained for a predefined period before deletion.
Option 2: The bindings are automatically transferred to a default group.
Option 3: The user's functional alias to group bindings are deleted.
Option 4: The bindings are updated to reflect the user's new affiliation status.
Explanation: After an MC service log-off, the system deletes the user's existing functional alias to group bindings for security and resource management. This ensures resources are freed up and security is maintained by not retaining potentially sensitive associations post-logoff, highlighting the importance of session management in telecom networks, especially in mission-critical communications.
