Refer to the exhibit.



An engineer is deploying mobile and remote access in an environment that already had functioning Business to Business calling. Mobile and remote access SIP registrations are failing. To troubleshoot, SIP logs were collected. How is this issue resolved?

  1. Change the SIP profile on the SIP trunk for the Expressway-E to Standard SIP Profile for TelePresence Endpoint
  2. Change the ג€Incoming Portג€ in the SIP Trunk Security Profile for the Expressway-C to not match SIP line registrations
  3. Enable autoregistration for the appropriate DN range on the Cisco UCM servers running the CallManager service
  4. Write a custom normalization script since the ג€vcs-interopג€ normalization script does not allow registrations

Answer(s): B



Refer to the exhibit.


Logins and failing via mobile and remote access. How is this resolved?

  1. 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.
  2. SIP is disabled on the Expressway-E. The SIP protocol must be enabled on the server.
  3. No Cisco UCM servers are configured in the Expressway- Servers must be added for CallManager and IM and Presence services.
  4. Although a traversal client zone exists, there is no Unified Communications traversal client zone. One must be created.

Answer(s): C



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?

  1. The listening port on the Expressway-C for SIP TCP must be changed to a value other than 5060
  2. The listening port on the Expressway-C for SIP TLS must be changed to a value other than 5061
  3. The listening port on the Cisco UCM for the Expressway-C SIP trunk must be changed to something other than 5060 or 5061
  4. 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

Answer(s): A



Refer to the exhibit.



The administrator attempted to log in, but Jabber clients cannot log in via mobile and remote access. How is this issue resolved?

  1. Skype for Business mode must be disabled on the DNS server because it conflicts with Jabber login requirements.
  2. The domain pod1.local must be deprovisioned from the Webex cloud for Jabber logins.
  3. A DNS SRV record must be created for _collab-edge._tls.pod1.local that points to the Expressway-E.
  4. The username jabberuser@pod1.local is invalid. The user should instead sign-in simply as jabberuser.

Answer(s): C





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?

  1. The Expressway-E certificate includes the Expressway-C FQDN as a SAN entry
  2. The Expressway-C is missing the FQDN of Cisco UCM in the Common Name of its certificate
  3. 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
  4. The Expressway-E does not have the FQDN of Cisco UCM listed as a SAN in its certificate

Answer(s): D
