Implementing Cisco Collaboration Applications (CLICA) — Question 94

An engineer is configuring a remote Cisco IM and Presence Service and needs to ensure that users can communicate across clusters in the same domain and receive presence status. Which protocol should be used to accomplish this task?

Answer options

• A. LDAP
• B. AXL/SOAP
• C. DNS
• D. XMPP

Correct answer: D

Explanation

The correct answer is D, XMPP, as it is designed for real-time communication and presence information across different clusters. LDAP, AXL/SOAP, and DNS do not provide the necessary capabilities for user presence sharing and real-time communication between clusters.
