cisco 300-820 practice test

An administrator made changes to a directory connector for Webex AD synchronization. The number of users synchronized is quite large and the change should affect only a limited number of users. How can the administrator check the result before executing the synchronization?

• A. Initiate an incremental synchronization from the Director Connector app on the on-premises Windows server because it will ask to save the changes.
• B. Initiate a dry run of an incremental synchronization from the Director Connector app on the on-premises Windows server.
• C. Initiate a dry run of an incremental synchronization from the Director Connector in Control Hub.
• D. Initiate an incremental synchronization from the Director Connector in Control Hub because it will ask to save changes.

DRAG DROP

Drag and drop the required SAN field items from the left onto the features within the server categories on the right.

What is the last step for domain management in Cisco Webex Control Hub if an engineer adds users already signed in with the company domain?

• A. Publish a domain.
• B. Add a domain.
• C. Verify a domain.
• D. Claim a domain.

Which two statements about Cisco Webex Video Mesh Nodes are true? (Choose two.)

• A. When Expressway Core works with VMN clusters, Expressway Core decides which VMN is used for signaling/media connection.
• B. Cloud-registered devices choose a VMN cluster based on the lowest STUN round trip delay.
• C. The cascading traffic between VMN must bypass the firewall.
• D. When Cisco Unified Communications Manager works with multiple VMNs, Cisco Unified CM decides which VMN is used for signaling connection.
• E. A VMN can terminate a media connection while operating in maintenance mode.

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

• 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.

Which dial plan component is configured in Expressway-C to route a call to the Cisco UCM?

• A. call routing
• B. traversal subzone
• C. call policy
• D. search rule

What is the Cisco-recommended key length in bits for a Cisco Expressway certificate?

• A. 1024
• B. 2048
• C. 4096
• D. 8192

A call is sent by Cisco UCM to Expressway with a URI of [email protected]?

• A. \1@conf\.pod8.test.lab.@
• B. \1@conf\.pod8\.test\lab.*
• C. \[emailprotected]\.test\.lab
• D. \1@conf\.pod8\.test.lab.!

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?

• A. Create a presearch transform.
• B. Change the domain of SIP endpoint A to cisco.com.
• C. Disable SIP in the external zone.
• D. Change the interworking mode to On.

Refer to the exhibit. Logins and failing via mobile and remote access. How is this resolved?

• A. Mobile and remote access login has not been enabled for the domain configured in the Expressway-C. The domain must be edited to allow Cisco UCM registrations.
• B. SIP is disabled on the Expressway-E. The SIP protocol must be enabled on the server.
• C. No Cisco UCM servers are configured in the Expressway-C. Servers must be added for CallManager and IM and Presence services.
• D. Although a traversal client zone exists, there is no Unified Communications traversal client zone. One must be created.
