Which two options are reasons for using traffic classification? (Choose two.)
A. to use the classification to route traffic
B. to use the classification to reorder packets from various sources
C. to use the classification to discard malformed packets
D. to use the classification to provide the configured service level
Classification entails using a traffic descriptor to categorize a packet within a specific group to define that packet and make it accessible for QoS handling on the network. Using packet classification, you can partition network traffic into multiple priority levels or classes of service.
