When viewing the configuration of Intercluster Lookup Service, this command is used to look up the URl of a remote cluster user:
Admin:utils ils lookup [email protected]
Routing string is cucm1.cisco.com
Which configuration is required on Cisco Unified Communications Manager, in order to allow routing calls to the URl of this remote cluster user?
A. SIP route pattern for domain*.acme.com
B. SIP trunk with destination cucm1.cisco.com
C. end user with directory URl [email protected]
D. SIP route pattern for domain*cisco.com
Chek the Routing Directory URIs, i think the correct answer is A, route Sip acme.com

The answer is D. Route patterns, URIs, DNs, are learnt from neighbour cluster along with the cluster route string.
Your cluster then needs a route pattern (which matches the route string), the destination is the remote UCM from which you learnt the URIs , and the route string
