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

  1. Webex Cloud supports either a DMZ-based Mesh Node for security or an internal-based Mesh Node for media control only.
  2. 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.
  3. 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.
  4. 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.

Answer(s): C



Where are voice calls handled in a Cisco Jabber hybrid cloud-based deployment with Cisco Webex Platform Service?

  2. The call is queued.
  3. The call fails.
  4. Another node in the cluster is used and an intra-cluster cascade between Webex and the new Video Mesh node is formed.

Answer(s): D



An organization wants to enable a Cisco Webex connector to synchronize all employees automatically with Cisco Webex instead of using a manual list.
Where is the Webex Hybrid Directory Service configured?

  1. Install Cisco Directory Connector on a Microsoft Windows Domain server and configure the software and Webex Control Hub.
  2. Enable the directory service in Cisco Unified Communications Manager under Cisco Unified Serviceability and add the service in Webex Control Hub.
  3. Enable the directory service on Cisco Expressway Edge for Office 365 or Cisco Expressway Core for internal Active Directory and add the service in Webex Control Hub.
  4. Install the Cisco Express Connector and configure the device in Cisco Unified Communications Manager under Cisco Unified Serviceability and add the service in Webex Control Hub.

Answer(s): A



With QoS enabled, which two statements about the Cisco Webex Video Mesh Node signaling and media traffic are true? (Choose two.)

  2. From VMN to Webex Teams clients, the source UDP port 5004 is used for video traffic.
  3. From Webex cloud to VMN, the source UDP port 9000 is used for audio traffic.
  4. From VMN to video endpoints, the destination UDP port 5004 is used for audio traffic.
  5. From VMN to Webex cloud, the destination UDP port 9000 is used for video traffic.
