Which two devices are supported by the Flexible DSCP Marking and Video Promotion feature? (Choose two.)

MGCP (Media Gateway Control Protocol) devices are not the primary target for the Flexible DSCP Marking and Video Promotion feature, which is more focused on IP phones and MTPs.

SCCP (Skinny Client Control Protocol) devices, such as various Cisco IP Phones, leverage the Flexible DSCP Marking and Video Promotion feature to ensure proper QoS marking for their media streams.

Pass-through Media Termination Points (MTPs) are supported by this feature, allowing them to participate in QoS by honoring and preserving DSCP markings for video traffic.

H.323 trunks are generally configured for QoS using different mechanisms and are not directly managed by the Flexible DSCP Marking and Video Promotion feature.

While the DX80 is a video endpoint, the feature specifically refers to device *types* (like SCCP or MTPs) that support the dynamic marking capabilities, not a particular model as the primary answer.
