An engineer must help a customer's administrator to set QoS options for the cluster. What are two QoS settings on the Cisco UCM server? (Choose two.)
The correct answer is A. Have the option to set the DSCP values for "video calls", "audio portion of the video calls", and C. The option "DSCP for Video" sets the DSCP value for all types of video to the same value. Two QoS settings on the Cisco UCM server are the options to set distinct DSCP values for video calls, audio portions of video calls, and audio calls, and the functionality where the "DSCP for Video" option applies a single DSCP value to all video types.

Why each option
Two QoS settings on the Cisco UCM server are the options to set distinct DSCP values for video calls, audio portions of video calls, and audio calls, and the functionality where the "DSCP for Video" option applies a single DSCP value to all video types.
Cisco UCM provides granular control over Quality of Service by allowing administrators to configure separate DSCP values. These distinct settings are available for pure audio calls, the audio streams embedded within video calls, and the video streams themselves, enabling precise traffic prioritization.
Configuring QoS parameters in the Enterprise Parameter section is incorrect; QoS settings are primarily found within the Service Parameters for specific services like Cisco CallManager.
The "DSCP for Video" option within Cisco UCM's QoS parameters simplifies video traffic marking by setting a single, uniform DSCP value. This ensures consistent prioritization for all types of video communication handled by the system, streamlining QoS policy application.
Configuring QoS parameters in the Cisco CallManager Service Parameter section describes *where* the settings are located, but it is not a *setting* itself; the question asks for two QoS settings.
