Question 1

An engineer must configure Mobile and Remote Access. One of the requirements is to expect Cisco Jabber users to enter username@cisco.com as the login userid. Which DNS record must the engineer modify to start implementing this requirement?

A : _cuplogin._tcp.cisco.com

B : collab-edge._tls.cisco.com

C : _cisco-uds._tls.cisco.com

D : _cisco-uds._tcp.cisco.com

Answer: B

Question 2

Refer to the exhibit.

Calls to locally registered endpoints are failing. At present, there are two endpoints registered locally to this Expressway. An H.323 endpoint with an alias of “EndpointA” is registered, and a SIP endpoint with an alias of “EndpointB@pod1.local” is also registered. How is this issue resolved?

A : The dialplan must be redesigned to use the transforms to convert the alias into SIP URI format and then use separate search rules for each format that needs to be dialed within the local zone.

B : The calls are failing because there are insufficient licenses. Additional licenses must be installed for the Expressway to route these calls.

C : The current search rule does not match the call, so the search rule must be modified to include a SIP Variant of “Standards-Based”.

D : Calling parties are placing calls with the wrong domain. End-users must be instructed not to use the pod1.local domain as that is owned by the local system. Calls to any other domain would work.

Answer: A

Question 3

Refer to the exhibit. When users sign in to Cisco Jabber through Mobile and Remote Access, they cannot see their own photo or the photo of their contacts next to each name. Which action must be taken in Cisco Expressway-C to resolve the issue?

B : Add an allow call policy rule from the Cisco UCM traversal zone.

C : Upload the missing Instant Messaging and Presence server certificate to fix the connection to its server.

Answer: A

Question 5

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?

A : Change the SIP profile on the SIP trunk for the Expressway-E to Standard SIP Profile for TelePresence Endpoint

B : Change the “Incoming Port” in the SIP Trunk Security Profile for the Expressway-C to not match SIP line registrations

C : Enable autoregistration for the appropriate DN range on the Cisco UCM servers running the CallManager service

D : Write a custom normalization script since the “vcs-interop” normalization script does not allow registrations
