NEW QUESTION 45
Refer to the exhibit.

In an environment SIP devices are registered to CUCM and H.323 devices to VCS. What would be required to enable these calls to setup correctly?

Create a presearch transform.

Change the domain of SIP endpoint A to cisco.com.

Disable SIP in the external zone.

Change the interworking mode to On.

NEW QUESTION 46
Which mode should be used when Call Policy is configured on Expressways?

extended CPL

local CPL, policy service, and off

remote CPL

NEW QUESTION 47
What should be considered when using the Cisco Webex hybrid service?

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.

NEW QUESTION 48
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.

NEW QUESTION 49
Which SIP media encryption mode is applied by default for newly created zones in the Cisco Expressway?

C…….

Auto

Force Encrypted

Best Effort

NEW QUESTION 50
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.

NEW QUESTION 51
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.

NEW QUESTION 52
Refer to the exhibit.

Refer to the exhibit. A Cisco Webex device on an enterprise network has identified the given STUN round-trip delays in milliseconds to the enterprise Video Mesh clusters and two Webex Cloud Media clusters during the call setup. Which correct sequence of clusters is the client connecting to?

US West Coast WCMC. If US West Cost WCMC is full, then Europe WCMC because clients select clusters in the order of SRT delays.

DC Europe. If DC Europe is full, DC APAC because clients select on-premises clusters in the order of SRT delays before using cloud resources.

DC Europe. If DC Europe is full, US West Coast WCMC because clients select resources in the order of SRT delays but ignore SRTs greater than 250 ms.

US West Coast WCMC. Clients continuously monitor DC US cluster and reconnect when DC US are available to save bandwidth.

NEW QUESTION 53
Which step is taken when configuring a Cisco Expressway solution?

Configure the Expressway-E by using a non-traversal server zone.

Enable static NAT on the Expressway-E only.

Disable H.323 mode on the Expressway-E.

Enable H.323 H.460.19 demultiplexing mode on the Expressway-C.

NEW QUESTION 54
An engineer noticed that internal participants using Full HD endpoints are joining meetings hosted in the Video Mesh node. The quality of the calls is 720p. What must the engineer configure to support 1080p quality?

Set the “Enhanced Layout Experience” within the Video Mesh settings in Cisco Webex Control Hub to 1080P HD video.

Set the “Received Video Resolution” on the Video Mesh node to maximum.

Turn on the “Enable 1080P HD video for all participants hosted on on-premises Video Mesh nodes” setting in the Cisco Webex Control Hub.

Turn on the “Highest Detail, Best Motion: 1080P” setting in the Cisco Webex Control Hub.

NEW QUESTION 55
An administrator has been tasked to bulk entitle 200 existing users and ensure all future users are automatically configured for the Webex Hybrid Calendar Service.
Which two options should be used to configure these users? (Choose two.)

Export a CSV list of users in the Cisco Webex Control Hub, set the Hybrid Calendar Service to TRUE for users to be enabled, then import the file back to Manage Users menu in the Cisco Webex Control Hub.

Set up an Auto-Assign template that enables Hybrid Calendar.

Select the Hybrid Services settings card in the Cisco Webex Control Hub and import a User Status report that contains only users to be enabled.

On the Users tab in the Cisco Webex Control Hub, check the box next to each user who should be enabled, then click the toggle for the Hybrid Calendar service to turn it on.

From Cisco Webex Control Hub, verify the domain that your Hybrid Calendar users will use, which automatically activates them for the service.
