CCNA: Cisco Certified Network Associate — Question 390

Which QoS traffic handling technique retains excess packets in a queue and reschedules these packets for later transmission when the configured maximum bandwidth has been surpassed?

Answer options

Correct answer: D

Explanation

The correct answer is traffic shaping, which involves delaying packets to ensure that the data transmission stays within the specified bandwidth limits. Traffic policing, on the other hand, drops packets that exceed bandwidth limits instead of queuing them. Weighted random early detection is a mechanism for congestion avoidance rather than managing bandwidth, while traffic prioritization focuses on giving preference to certain packets rather than controlling their flow.
