Refer to the exhibit.

In this high-availability Cisco IM and Presence deployment with three subclusters, the first user is assigned to server 1A; the second user is assigned to server 2A; and the third user is assigned to server 3A.
Assume that the Cisco IM and Presence is set to Active/Standby mode, to which server should the fourth user be assigned?
Correct Answer: A
Explanation/Reference:
Explanation: This deployment model provides the same level of redundancy and high availability as outlined in the "Balanced Redundant High-Availability Deployment" section in this chapter. The only difference is that users are not deployed in a balanced fashion, but rather all reside on the primary server in the subcluster, and the backup server is there as a standby option if a node failure occurs.
