Drag and Drop Question Drag and drop the characteristics from the left onto the QoS components they describe on the right. Answer:

The correct answer is process used to buffer traffic that exceeds a predefined rate; applied on traffic to convey information to a downstream device; permits traffic to pass through the device while retaining DSCP/COS values; distinguishes traffic types. In QoS, each component has a distinct role: Policing buffers or drops traffic exceeding a predefined rate, Marking applies information (like DSCP/CoS values) to packets to convey priority to downstream devices, Trust allows traffic to pass through while honoring existing…

Correct arrangement

applied on traffic to convey information to a downstream device
permits traffic to pass through the device while retaining DSCP/COS values
distinguishes traffic types

Explanation

In QoS, each component has a distinct role: Policing buffers or drops traffic exceeding a predefined rate, Marking applies information (like DSCP/CoS values) to packets to convey priority to downstream devices, Trust allows traffic to pass through while honoring existing DSCP/CoS markings, and Classification distinguishes traffic types by identifying and categorizing flows. These four functions work together in a QoS policy to manage network traffic effectively.
