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?
Refer to the exhibit. An administrator troubleshoots Cisco Jabber users experiencing issues when trying to log in and notices errors in the Jabber problem report log. The administrator also sees that the Intercluster Sync Agent service is not running on the IM and Presence server. Why is the Jabber client unable to sign in?
An engineer is supporting an existing Cisco Collaboration deployment that has internal and external home users using the solution without VPN. Business usage also includes B2B calling for voice and video.

Employees at company A must call employees at company B in an extension range of 4XXX@companyB.com. Both companies have a Cisco collaboration infrastructure. All required zones are configured in Cisco Expressways at company A. What must be configured on the Expressway at company A to enable outbound B2B calls?
In a Webex Video Mesh deployment, where do Cloud-registered Webex Teams clients and devices send signaling traffic for call setup?
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?
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?
Which method is used to send the incoming call request to the client when the traversal server receives an incoming call for the traversal client?
Which SIP media encryption mode is applied by default for newly created zones in the Cisco Expressway?
Refer to the exhibit. When users sign in to Cisco Jabber through Mobile and Remote Access, they cannot see their own photo or the photo of their contacts next to each name. Which action must be taken in Cisco Expressway-C to resolve the issue?
Refer to the exhibit. A collaboration engineer is configuring Cisco Expressway for B2B calling. The engineer must allow inbound calls to be routed to Cisco UCM. The traffic must be unencrypted between the Expressway-C and the Cisco UCM cluster. Which configuration correctly implements the zone?
A)
B)
C)
D)

Which two types of information does Cisco Expressway back up? (Choose two.)
Refer to the exhibit.
When a Jabber user attempts to connect from outside of the organization, the user enters the login information as "user@example.com" and receives the error "Cannot find your services Automatically". The engineer tries to resolve SRV records used by Jabber.
DNS A record "expressway-e.example.com" points to the Expressway-E IP and "cucm.example.com" points to the Cisco Unified Communications Manager.
