C.
Gatekeeper Call Admission Control applies only to distributed Cisco Unified Communications Express deployments.

D.

Explanation:
Incorrect answer: A, C, D

in distributed call processing deployments on a simple hub-and-spoke topology, you can implement call admission control with a Cisco IOS
gatekeeper. In this design, the call processing agent (which could be a Unified CM cluster, Cisco Unified Communications Manager Express (Unified CME), or an
H
323 gateway) registers with the Cisco IOS gatekeeper and queries it each time the agent wants to place an IP WAN call.
