Implementing Cisco Video Network Devices (CIVND, legacy) — Question 15

Which of the following first provided centralized call control capabilities for H.323 video endpoints?

Answer options

Correct answer: D

Explanation

The correct answer is D, MCU, as it is responsible for managing multiple video streams and providing centralized control. The Gatekeeper (A) is primarily focused on address resolution and bandwidth control, while CUCM (B) is a call management system and MGCP (C) is a protocol for controlling media gateways, but they do not provide the same level of centralized call control for video endpoints as the MCU.
