Question 1

An engineer is configuring the Expressway cluster to allow Jabber clients that are outside the enterprise network to register, make calls, and send instant messages using the internal Cisco UCM. Which action must be taken before a secure UC traversal zone is added to the Expressway-C?

A : Add Instant Message and Presence service clusters.

B : Add a Cisco UCM cluster.

C : Configure SIP OAuth mode.

D : Establish certificate trust between the Expressway-C and Expressway-E.

Answer: D

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

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