Front

What does CBWFQ stand for?

Back

Front

What is the main difference between FIFO and WFQ?

Back

FIFO queues packets in order of arrival, while WFQ classifies and schedules them.

Front

Which of the following is a feature of WFQ? It provides strict priority to voice traffic., It fairly shares remaining bandwidth among flows., It guarantees minimum bandwidth for each class., It uses packet size as a classification criterion.

Back

It fairly shares remaining bandwidth among flows.
