Questions # 13:

A MRA deployment is being configured where one of the requirements is for registered Jabber users to pull directory photos from an internal server. What should be configured on the Expressway-C so that MRA registered clients reach this server?

Question # 14

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?

Options:

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.

Questions # 15:

Which dial plan settings can be used to set up different regulations according to the protocol (SIP or H.323) or the source of the query?

Options:

A.

presearch transforms

B.

search rules

C.

call policy

D.

policy services

C.

The cascading traffic between VMN must bypass the firewall.

D.

When Cisco Unified Communications Manager works with multiple VMNs, Cisco Unified CM decides which VMN is used for signaling connection.

E.
