Which part of a hybrid cloud-based deployment with Cisco Webex Messenger Service is used for meeting

capabilities?

Options :

A :

Cisco Unified CM is always used for meeting capabilities.

B :

Depending on the media flow, the Webex Meeting Center or local Cisco Unified CM meeting resources

are used for meeting capabilities.

C :

Depending on the origin of the user, the Webex Meeting Center or local Cisco Unified Communications

Manager meeting resources are used for meeting capabilities.

Question 2

Which two internal SIP endpoints behind a firewall place calls to external devices? (Choose two.)

Options :

A : An Expressway-C communicates with the internal endpoint and forwards the media to and from an Expressway-E.

B : A Cisco Endpoint is configured with a publicly routable static NAT SIP address to advertise instead of is private IP address.

C : An Expressway-C communicates directly with the remote party using the ICE protocol

D : An Expressway-E is used as a VPN server to allow remote SIP edge servers to connect calls

E : An Expressway-C rewrites the SIP SDP to advertise its own IP address to the external party.

Answer: A,D

Question 3

300-820-page39-image6

Refer to the exhibit. 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?

Options :

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.

Answer: D

Question 4

Where are voice calls handled in a Cisco Jabber hybrid cloud-based deployment with Cisco Webex

Platform Service?

Options :

A : Voice calls use Webex Calling platform for call control and use hybrid media nodes for local conferencing.

C : Voice call use Cisco Unified Communications Manager for local calls and Webex Calling for external calls.

D : Voice calls use local Cisco Unified Communications Manager for all calls.

Answer: D

Question 5

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?

Options :

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

B : 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,

C : 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

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

Answer: A
