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.
Refer to the exhibit showing logs from the Expressway-C, a copy of the Expressway-E certificate, and the UC traversal zone configuration for the Expressway-C. An office administrator is deploying mobile and remote access and sees an issue with the UC traversal zone. The zone is showing "TLS negotiation failure".
What is causing this issue?
A. The Expressway-E certificate includes the Expressway-C FQDN as a SAN entry
B. The Expressway-C is missing the FQDN of Cisco UCM in the Common Name of its certificate
C. In the UC Traversal Zone on the Expressway-C, the peer address is set to the IP of the Expressway-E, which is not a SAN entry in the Expressway-E certificate
D. The Expressway-E does not have the FQDN of Cisco UCM listed as a SAN in its certificate
Cisco media traversal technology has enabled a secure environment where internal video endpoints call and receive calls from external video endpoints. How does the Expressway- C and Expressway-E communicate?
A. Expressway-C establishes an outgoing request to Expressway-E, enabling the Expressway-E in the DMZ to notify the internal Expressway-C of an incoming call from an external endpoint.
B. Internal endpoints are registered to Expressway-E in the DMZ. Expressway-C, which is also in the DMZ, will receive and make calls on behalf of Expressway-E because they are in the same network.
C. Expressway-E establishes an outgoing request to Expressway-C, enabling the Expressway-C in the DMZ to notify the internal Expressway-E of an incoming call from an external endpoint.
D. Internal endpoints are registered to Expressway-C in the DMZ. Expressway-E, which is also in the DMZ, will receive and make calls on behalf of Expressway-C because they are in the same network.
Which attribute in the SDP for a call is affected by the static NAT address configuration in an Expressway-E?
A. connection
B. name
C. version
D. bandwidth
Which protocol should be used to verify the connectivity for different media paths found during a call using ICE?
A. STUN
B. RTP
C. SNMP
D. TURN
Which step is required when configuring Cisco Webex Hybrid Message Service?
A. Add Expressway-C and Cisco UCM to the Cisco Webex Cloud.
B. Register Expressway-C Connector Hosts to the Cisco Webex Cloud.
C. Add Cisco Unity Connection to Expressway-E.
D. Register Expressway-C to Cisco UCM.
Refer to the exhibit. Call policy rules on an Expressway-E prevent external callers from the internet from calling a VIP whose URI is [email protected]. Which additional configuration setting is required for this call policy to function as intended?
A. The default zone on the Expressway-E must not be configured to treat as authenticated.
B. A search rule must be configured with an extract match for [email protected] to pass the call to the Expressway-C.
C. The Cisco TelePresence endpoint registered with the URI [email protected] must be set in "do not disturb" mode.
D. SIP TLS must be disabled on the Expressway-E.
An administrator is enabling Mobile and Remote Access login for the Cisco UCM registration domain cisco.com. Phones are registered with a Cisco UCM phone security profile name of securephone.cisco.com. Which two subject alternative names must be configured? (Choose two.)
A. Securephone.cisco.com on the CallManager certificate
B. cisco.com on the Expressway-C certificate
C. Securephone.cisco.com on the Expressway-E certificate
D. cisco.com on the Expressway-E certificate
E. Securephone.cisco.com on the Expressway-C certificate
Refer to the exhibit. When Expressway-E routes a call with URI [email protected] to a DNS zone, which DNS server does the Expressway query for the SIP SRV records?
A. 10.20.20.20
B. 10.10.10.10
C. 10.40.40.40
D. 10.30.30.30
