Which statement about the Cisco Webex hybrid service is true?
Expressway Connector is required for an on-premises Exchange server.
Hybrid Message service works only with Jabber cloud deployment.
Directory Connector is required for Azure AD.
Directory Connector must be deployed for OBTP to work with on-premises video devices.
Which two statements about Cisco Webex Video Mesh Nodes are true? (Choose two.)
When Expressway Core works with VMN clusters, Expressway Core decides which VMN is used for signaling/media connection.
Cloud-registered devices choose a VMN cluster based on the lowest STUN round trip delay.
The cascading traffic between VMN must bypass the firewall.
When Cisco Unified Communications Manager works with multiple VMNs, Cisco Unified CM decides which VMN is used for signaling connection.
A VMN can terminate a media connection while operating in maintenance mode.
Refer to the exhibit. If the Webex Teams device cannot connect to Video Mesh Cluster-1 because it is busy, which media node does the Webex Teams device connect to next?
Both Cloud Node US-EAST and US-WEST
Video Mesh Cluster-2
Cloud Node US-EAST
Cloud Node US-WEST
A Cisco Webex Hybrid Video Mesh Node can be installed in the DMZ and on the internal network.
Which statement is true?
Webex Cloud supports either a DMZ-based Mesh Node for security or an internal-based Mesh Node for media control only.
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.
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.
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.
Where are voice calls handled in a Cisco Jabber hybrid cloud-based deployment with Cisco Webex Platform Service?
Voice calls use Webex Calling platform for call control and use hybrid media nodes for local conferencing.
Voice calls use local media nodes to keep traffic internal for internal traffic and use Webex Calling for external calls.
Voice call use Cisco Unified Communications Manager for local calls and Webex Calling for external calls.
Voice calls use local Cisco Unified Communications Manager for all calls.
Refer to the exhibit. Cisco Unified Communications Manager routes the call via the Webex Meetings route list and route group to the Video Mesh cluster Node#1 in the Video Mesh cluster is hosting the meeting and has reached full capacity, but other nodes in the cluster still have spare capacity.
What happens to the participant's call?
Another node in the cluster is used and an intra-cluster cascade between the two Video Mesh nodes is formed.
The call is queued.
The call fails.
Another node in the cluster is used and an intra-cluster cascade between Webex and the new Video Mesh node is formed.
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?
Install Cisco Directory Connector on a Microsoft Windows Domain server and configure the software and Webex Control Hub.
Enable the directory service in Cisco Unified Communications Manager under Cisco Unified Serviceability and add the service in Webex Control Hub.
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.
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.
