Implementing Cisco Collaboration Cloud and Edge Infrastructure (CLCEI) — Question 119

A company has an on-premises Cisco collaboration cluster that contains Cisco UCM, IM and Presence, and Cisco Webex in the cloud. The company wants to integrate the on-premises infrastructure with Webex to enable interoperability with the Webex App. An engineer already configured the cluster in Cisco UCM, IM and Presence, and the organization in the Webex Control Hub. Which action must the engineer take to complete the configuration?

Answer options

• A. Deploy Directory Connector.
• B. Open the TCP 443 port from IM and Presence to Webex Cloud.
• C. Deploy a Webex Device Connector.
• D. Deploy a Cisco Expressway Message Connector host.

Correct answer: D

Explanation

The correct action is to deploy a Cisco Expressway Message Connector host, as it is necessary for secure communication between on-premises systems and the Webex cloud. The other options either do not directly relate to the required interoperability or are not sufficient to complete the integration process.
