Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

D is correct because MGCP (Media Gateway Control Protocol) is specifically designed for centralized gateway control, where Media Gateway Controllers (Call Agents) control Media Gateways - all call intelligence resides in the controller. A (SIP) is a peer-to-peer distributed protocol. B (SCCP) controls IP phone endpoints, not gateways. C (H.323) is also peer-to-peer, not centralized gateway control.
