CCNA: Cisco Certified Network Associate — Question 1288

Which QoS queuing method discards or marks packets that exceed the desired bit rate of traffic flow?

Answer options

• A. CBWFQ
• B. policing
• C. LLQ
• D. shaping

Correct answer: B

Explanation

The correct answer is 'policing' because it specifically regulates traffic by dropping or marking packets that exceed the defined rate. The other options, such as CBWFQ and LLQ, focus on prioritizing traffic rather than enforcing a strict rate limit, while shaping is used to smooth out traffic flows rather than immediately discard or mark excess packets.
