Configure Cisco IM and Presence Server High Availability

C.

The correct answer is C. System > Presence Redundancy Groups.

In Cisco Unified Communications Manager (CUCM), Cisco IM and Presence Server (IM&P) High Availability is configured using Presence Redundancy Groups. Presence Redundancy Groups allow for the configuration of a primary and secondary IM&P server in a cluster, and ensure that user presence information is available even if the primary server fails.

To configure Presence Redundancy Groups for Cisco IM&P High Availability, follow these steps:

1. Log in to Cisco Unified Communications Manager Administration.

2. Choose System > Presence Redundancy Groups.

3. Click the Add New button to create a new Presence Redundancy Group.

4. In the Add New Presence Redundancy Group window, enter a name for the new redundancy group.

5. Select the Primary and Secondary servers that will be part of the redundancy group from the drop-down menus.

6. Click Save to save the new Presence Redundancy Group.

After the Presence Redundancy Group is created, you must enable it for the users who will be using Cisco IM&P. To do this, follow these steps:

1. Choose User Management > End User.

2. Find the user for whom you want to enable Cisco IM&P High Availability.

3. Click on the user's name to open the End User Configuration window.

4. In the End User Configuration window, scroll down to the IM&P settings section.

5. Select the Presence Group that you created earlier from the drop-down menu.

6. Click Save to save the changes to the user's configuration.

Repeat these steps for each user who will be using Cisco IM&P.

By configuring Presence Redundancy Groups in Cisco Unified Communications Manager, you can ensure that Cisco IM&P is highly available and that user presence information is always accessible.
