Which two outbound connections should an administrator configure on the internal firewall? (Choose two.)

A. XMPP: TCP 7400

B. SIP: TCP 7001

C. SIP TCP 5061

D. Media: UDP 36012 to 59999

E. HTTPS: TCP 8443

An Expressway-C and Expressway-E are configured for B2B calling and the Expressway- E zone is set to TLS Verify Currently, calls do not reach the Expressway-C. The Traversal Client zone on the Expressway-C for B2B reports the information in the exhibit for the Peer 1 address.

Which action resolves this error?

A. Configure the Expressway-C Traversal Client zone Peer 1 address with the fully qualified domain name of the Expressway-E.

B. Configure the Expressway-C Traversal Client zone transport protocol with TCP.

C. Add a server certificate to the Expressway-C that is signed by a certificate authority.

D. Add an intermediate certificate to the Expressway-C that is signed by a certificate authority.

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?

A. Install Cisco Directory Connector on a Microsoft Windows Domain server and configure the software and Webex Control Hub.

B. Enable the directory service in Cisco Unified Communications Manager under Cisco Unified Serviceability and add the service in Webex Control Hub.

C. 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.

D. 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.

What it is the purpose of using ICE for Mobile and Remote Access endpoints in the Cisco Collaboration infrastructure?

A. ICE controls the bandwidth usage for Cisco Collaboration endpoints if the endpoints are located outside the company network.

B. ICE enables Cisco Collaboration endpoints to determine if there is direct connectivity between them.

C. ICE uses FAST updates to optimize the video quality in case of packet loss. This technology is available only from Cisco Unified CM version 11.5 and later.

D. ICE enablement allows for the Cisco Collaboration endpoint to register through Expressway servers to Cisco Unified Communications Manager behind a firewall.

An engineer learns from an end user that calls from outside the company are not being received. Calls are being made to other businesses outside of the company on video using URL addresses. The change management log shows no changes in the configuration of the collaboration solutions. The engineer examines the endpoint, which seems to be registered to the Cisco UCM, and the SIP trunk between the Cisco UCM and sees that the Expressway is also up. In addition, the traversal link shows no errors between the Expressways. Which action must the engineer take to troubleshoot this issue?

A. On the Cisco UCM, run the Real-Time Monitoring Tool to see if any incoming calls fail.

B. On the Expressway-E, run diagnostic logging under maintenance to see if any requests reach the system.

C. On the Expressway-E, check the NTP settings to ensure that TLS will be able to terminate. If the clock is out of sync, incoming calls from other working systems would work bur not outgoing calls from the company.

D. On the Expressway-C, run a network log under administrative tools to see if any requests reach the system.
