cisco 300-820 practice test

Question 1

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.

Question 2

DRAG DROP

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

Question 3

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.

Question 4

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.

Question 5

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.

Question 6

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

Question 7

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

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

Question 8

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.!

Question 9

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.

Question 10

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.
