Which two gateways of trunks are considered to be call-agent controlled? (Choose two.)
A. Skinny Client Control Protocol gateway
B. H.323
C. SIP trunk registered to a SIP proxy server
D. Media Gateway Control Protocol gateway
E. H.225 trunk (gatekeeper controlled)
I agree with answer A-D
H323 are not Call Agent controlled. H323 do not register with the CUCM, they are independent. That’s kind of the whole point behind H323.
Matter of fact MGCP gateways use H323 protocol as their fallback when they lose CUCM connectivity (if configured)
Answer is A and D. UCM acts as the call agent for both of these types of gateways.

Skinny Client Control Protocol (SCCP) gateways handle Cisco Unified Communications Manager redundancy, failover, and fallback in the same way as MGCP gateways.
Answer are D and E
I go back, the answer are right because a H.225 Trunk (Gatekeeper Controlled) can not be controlled by a call-agent.
Answer are B and D
