This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A category used by a policer to classify packets relative to the traffic contract. With two-color policers - these packets are considered to be above the contract; for three-color - these packets are above the Bc setting - but within the Be setting.
