Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 288

Which configuration concept allows for high-availability on IM and Presence services in a UC environment?

Answer options

• A. IM and Presence subclusters (configured on Cisco UCM)
• B. Presence Redundancy Groups (configured on Cisco UCM)
• C. Presence Redundancy Groups (configured on Cisco Unified IM and Presence)
• D. IM and Presence subclusters (configured on Cisco Unified IM and Presence)

Correct answer: B

Explanation

The correct answer is B, as Presence Redundancy Groups configured on Cisco UCM specifically enhance high availability for IM and Presence services. Options A and D refer to IM and Presence subclusters, which do not provide the same level of redundancy. Option C mentions the correct group but is configured on the wrong platform, making it incorrect.
