Which QoS feature drops traffic that exceeds the committed access rate?

Options

Apolicing
BFIFO
Cshaping
Dweighted fair queuing

Explanation

This question asks to identify the Quality of Service (QoS) feature responsible for dropping traffic that surpasses a defined rate limit.

Common mistakes.

B. FIFO (First-In, First-Out) is a basic queuing method that processes packets in the order they arrive, without any rate limiting or dropping based on exceeding a committed rate.
C. Shaping (traffic shaping) buffers excess traffic that exceeds the committed rate and sends it out later, smoothing the output rate, rather than dropping it immediately.
D. Weighted Fair Queuing (WFQ) is a scheduling algorithm that provides fair bandwidth allocation among different traffic flows based on weights, but it does not primarily drop traffic for exceeding a committed rate.

Concept tested. QoS policing vs shaping
