Implementing Cisco Collaboration Cloud and Edge Infrastructure (CLCEI) — Question 50

A Cisco Webex Hybrid Video Mesh Node can be installed in the DMZ and on the internal network.
Which statement is true?

Answer options

• A. Webex Cloud supports either a DMZ-based Mesh Node for security or an internal-based Mesh Node for media control only.
• B. Installing a Video Mesh Node in the DMZ requires you to open TCP and UDP port 4444 in your internal firewall for full clustering functionality.
• C. Installing a Video Mesh Node in the DMZ requires the external firewall to allow UDP traffic from ANY port to the address of the Video Mesh Nodes via port 5004.
• D. Using internal Video Mesh Node also works due to Mobile and Remote Access setup for Webex Teams clients. A DMZ node is added for extra security.

Correct answer: C

Explanation

The correct answer is C because installing a Video Mesh Node in the DMZ necessitates allowing specific UDP traffic for proper operation. Option A is incorrect as it misrepresents the functionality of the nodes, while Option B incorrectly states the port requirements for clustering. Option D, while mentioning valid features, does not address the specific requirements for DMZ installation.
