What is the recommended default value that is used between regions for video calls?

The correct answer is A. 384 Kbps. The recommended default inter-region video call bandwidth in Cisco CUCM is 384 Kbps, which balances standard-definition video quality against WAN bandwidth consumption.

Why each option

The recommended default inter-region video call bandwidth in Cisco CUCM is 384 Kbps, which balances standard-definition video quality against WAN bandwidth consumption.

A384 Kbps.Correct

Cisco CUCM sets 384 Kbps as the recommended default video bandwidth in the Region configuration because it delivers acceptable standard-definition video quality for most enterprise WAN deployments; this value caps the maximum video bit rate negotiated between endpoints in different regions, preventing over-subscription of inter-site links.

BG.722.

G.722 is a wideband audio codec operating at 64 Kbps and is not a video bandwidth value; it is used for high-fidelity voice calls and has no relevance to video region settings.

CG.711.

G.711 is a narrowband audio codec standardized at 64 Kbps and is used for voice, not for specifying video call bandwidth in CUCM region configuration.

DG.728.

G.728 is a low-bitrate voice codec at 16 Kbps designed for constrained voice links and has no connection to video call bandwidth settings in CUCM.
