The correct answer is C. two-token bucket algorithm. Cisco IOS QoS policing uses token bucket algorithms to measure traffic rates. A single-token bucket algorithm (also called one-rate two-color) has only two outcomes: conform and exceed-it uses two parameters (CIR and Bc). A two-token bucket algorithm (one-rate three-color or…

Explanation

Cisco IOS QoS policing uses token bucket algorithms to measure traffic rates. A single-token bucket algorithm (also called one-rate two-color) has only two outcomes: conform and exceed-it uses two parameters (CIR and Bc). A two-token bucket algorithm (one-rate three-color or two-rate three-color) has three outcomes: conform, exceed, and violate. The command shown defines three rate/burst parameters (8000 bps CIR, 1000-byte Bc, 1000-byte Be) and three actions (conform-action, exceed-action, violate-action), which is the signature of the two-token bucket algorithm (C). The presence of 'violate-action drop' is the definitive indicator that a second token bucket is in use.
