A presence redundancy group is deployed, and an engineer initiates a manual fallback.
Which statement about Cisco Server Recovery Manager is true?

A. B. C. D.B.
In a Cisco Collaboration environment, Presence Redundancy Group (PRG) is used to provide high availability of Cisco Unified Communications Manager (CUCM) and Cisco Unified Presence (CUP) services. In this setup, one node of CUP acts as the primary server, and another node acts as the secondary server.
If the primary CUP node fails, the secondary node takes over the services and starts serving user requests. When the primary node is back online, the system automatically fails back to the primary node. However, sometimes engineers need to initiate a manual fallback to the primary node, which can be done using the Cisco Server Recovery Manager tool.
The Cisco Server Recovery Manager is a tool used to automate the recovery of Cisco Unified Communications applications. It helps in automating the recovery process, reducing downtime and minimizing the impact on the user experience.
Now, coming to the question, the statement that is true regarding the Cisco Server Recovery Manager during a manual fallback is:
B. Disconnects all users that had been failed over
This statement is correct because when a manual fallback is initiated, the secondary node that had taken over the services disconnects all users that had been failed over to the secondary node. These users must log in again to regain access to the services. This is because the system fails back to the primary node, and the primary node has no knowledge of the users who were failed over to the secondary node.
Option A is incorrect because the Cisco Server Recovery Manager does not force users to log in again. It only disconnects users that had been failed over to the secondary node.
Option C is also incorrect because the Cisco Server Recovery Manager does not restart critical services on the secondary node during a manual fallback. Instead, it initiates the failover process from the secondary node back to the primary node.
Option D is incorrect because the Cisco Server Recovery Manager does not restart the Cisco Presence Engine during a manual fallback. Instead, it initiates the failover process from the secondary node back to the primary node.
