Implementing Cisco Collaboration Applications (CLICA) — Question 152

An organization wants to run on-premises instant messaging (IM), and resilience is important because this is a business-critical application for them. The organization has three locations with Cisco UCM clusters in each location. Which additional configuration is needed to meet these requirements?

Answer options

• A. Configure IMP functionality in Cisco UCM with failover. Cisco IM and Presence servers are not needed from systems release 14.X and newer.
• B. Deploy a minimum of two Cisco IMP servers per location, with one publisher and one subscriber connected to the existing local cluster.
• C. Expand the Cisco UCM cluster with Cisco IM and Presence nodes in each location.
• D. Deploy a central Cisco IM and Presence server at one central location because users will log in to Cisco UCM in case of a failover.

Correct answer: B

Explanation

The correct answer is B because deploying two Cisco IMP servers at each location ensures redundancy and availability, which is critical for business operations. Option A is incorrect as Cisco IM and Presence servers are still necessary for certain features. Option C does not ensure the immediate failover capability that B provides, and option D does not align with the requirement of having resilience across all locations.
