Exam 300-815 topic 1 question 129 discussion

I'd say it's B and E. There is no such thing as "called party URI transformation" See SIP Route pattern Configuration Setting: https://www.cisco.com/c/en/us/td/docs/telepresence/tcs/7_1/admin/administration/tcs_7_0/cucm.html

B. Partition of the SIP route pattern The partition determines which devices (phones, gateways, trunks, etc.) have access to the route pattern. By placing the SIP route pattern in a specific partition and assigning appropriate calling search spaces (CSS) to endpoints, the administrator can control which endpoints are allowed to reach *.webex.com. E. Destination SIP trunk of the SIP route pattern The SIP route pattern must be associated with the correct SIP trunk that directs calls to Webex. Without this, the traffic will not be routed properly.

I'd say it's B and E.

Answer is B and E. There isn't any Called party URI transformation configuration section under the SIP route pattern configuration. There are both Calling and Called party transformations but they DON'T HAVE TO be configured for the sip route pattern to work.

A and B are the only ones that make sense to me.

Two items B and D
