Implementing Cisco Collaboration Cloud and Edge Infrastructure (CLCEI) — Question 93

How is the communication routed in a Hybrid deployment so that people on Cisco Cloud-Based IM are able to communicate with Cisco Jabber users in the on-premises environment?

Answer options

• A. The Expressway-C enables a connection directly with the Cisco Webex Cloud to enable the hybrid service and allow the two services to communicate.
• B. The Expressway-E located in the DMZ establishes a connection with the Cisco Webex Cloud to enable the hybrid service and allow the two services to communicate.
• C. The Cisco Unified IM and Presence server establishes a connection using the outgoing path through the Cisco Expressways that terminates in the Cisco Webex Cloud to create the hybrid environment that links the two services together.
• D. The Cisco UC server establishes a connection using the outgoing path through the Cisco Expressways that terminates in the Cisco Webex Cloud to create the hybrid environment that links the two services together.

Correct answer: A

Explanation

The correct answer is A because the Expressway-C is specifically designed to create a direct connection to the Cisco Webex Cloud, facilitating communication between the two environments. Options B, C, and D are incorrect as they either refer to the wrong Expressway component or incorrectly describe the role of other servers in the hybrid setup.
