• Question 91:

  Between which two DTMF relay methods does the Expressway support interworking? (Choose two.)

  A. unsolicited notify

  B. RFC 2833

  C. KPML

  D. passthrough

  E. H.245 user input indication

  Correct Answer: BE

• Question 94:

  Refer to the exhibit.

  

  Mobile and remote access is being added to an existing B2B deployment and is failing.

  When the administrator looks at the alarms on the Expressway-C, the snippets are shown. Which configuration action should the administrator take to fix this issue?

  A. The listening port on the Expressway-C for SIP TCP must be changed to a value other than 5060

  B. The listening port on the Expressway-C for SIP TLS must be changed to a value other than 5061

  C. The listening port on the Cisco UCM for the Expressway-C SIP trunk must be changed to something other than 5060 or 5061

  D. The listening port on the Cisco UCM for the Expressway-C SIP trunk is set to something other than 5060 or 5061. It must be set to 5060 for insecure and 5061 for secure SIP

  Correct Answer: C

• Question 97:

  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

  Correct Answer: C

• Question 98:

  Refer to the exhibit.

  

  When configuring a search rule that routes calls to a zone, what occurs when 13358 is dialed?

  A. 13358 is replaced by 135, and then is sent to the local zone.

  B. 13358 is replaced by 135 and remains in the same zone.

  C. 13358 is replaced by 135, and then is sent to the traversal zone.

  D. 13358 is sent directly to the traversal zone.

  Correct Answer: D

• Question 99:

  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?

  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.

  Correct Answer: C

• Question 100:

  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.

  Correct Answer: D
