Exam 300-815 topic 1 question 86 discussion

CollabCorp is a global company with two clusters, emea.collab.corp and apac.collab.corp. URI dialing is implemented and working in each cluster. The company configured routing between clusters to make inter-cluster calls via URI, but this is not working as expected. Which two configuration elements should be checked to resolve this issue? (Choose two.) A. intercluster trunk B. directory URI partition C. SIP route pattern D. calling search space and partition E. SIP trunk

Correct Answers: CE When a user dials a learned directory URI that is registered to a remote cluster, Cisco Unified Communications Manager pulls the route string that is associated to that directory URI, matches that route string to a SIP route pattern, and routes the call to the outbound trunk that is specified by the SIP route pattern. In order for Cisco Unified Communications Manager to route calls to a route string, you must configure SIP route patterns that route the destination route strings to the next-hop clusters in your ILS network.

Going with C and D on this one. You have to have the correct SIP route patterns in place and have the privileges to reach them before anything else can be accomplished.
