Discuss Cisco 300-820 Exam Topic 26 Question 110

A Cisco Webex Hybrid Video Mesh Node can be installed in the DMZ and on the internal network.

Which statement is true?

AWebex Cloud supports either a DMZ-based Mesh Node for security or an internal-based Mesh Node for media control only.

BInstalling a Video Mesh Node in the DMZ requires you to open TCP and UDP port 4444 in your internal firewall for full clustering functionality.

CInstalling 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.

DUsing 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.
