What QoS step must occur before packets can be marked?
- queuing
- shaping
- policing
- classifying
Explanation & Hint:
Before packets can be marked in a Quality of Service (QoS) process, they must be classified. Classification is the step in QoS where packets are identified and categorized into specific traffic flows based on various criteria such as source and destination IP addresses, port numbers, or protocol type. This step is crucial as it determines how the network will handle these packets in subsequent QoS processes like marking, queuing, policing, or shaping.
