Question

What is the purpose of classifying network traffic in QoS?

A configures traffic-matching rules on network devices
B services traffic according to its class
C identifies the type of traffic that will receive a particular treatment
D writes the class identifier of a packet to a dedicated field in the packet header

Explanation

QoS classification determines which traffic category a packet or flow belongs to so the network can apply the appropriate policy and forwarding treatment to it. It is the identification step that distinguishes traffic types before actions such as queuing, policing, shaping, or marking are performed.
