Implementing Cisco Collaboration Applications (CLICA) — Question 55

A collaboration engineer troubleshoots an issue with Cisco IM and Presence federated with Microsoft Skype for Business. A Cisco Jabber user reports being unable to see the presence status of a user on Microsoft Skype for Business when searching for the Microsoft user. Which action resolves this issue?

Answer options

• A. Have the Jabber user add the Skype for Business user to the Jabber contact list.
• B. Disable TLS for the federation.
• C. Add a static route on Cisco IM and Presence to the Skype for Business domain.
• D. Configure the federation to use the XMPP protocol.

Correct answer: C

Explanation

The correct answer is C because adding a static route ensures that the Cisco IM and Presence server can properly communicate with the Skype for Business domain. Option A does not resolve the underlying connectivity issue, B would compromise security, and D would require a different configuration that may not be supported in this scenario.
