Explanation
In a Cisco IM and Presence High Availability (HA) configuration, 'Idle' on the primary node means it is not actively serving users, and 'running in backup mode' on the secondary means it has taken over but is not the designated primary. This state occurs after a failover event. To restore normal operation-where the primary node is active and the secondary is in standby-the engineer must click 'Fallback' in the Server Action field. Fallback triggers the primary node to resume its role. 'Failover' (option B) would only move active operation further away from the intended primary, and restarting or reinstalling would be destructive without addressing the HA state.
