Which QoS traffic-handling method keeps excess packets in a queue and schedules them for later transmission after the configured maximum bandwidth has been exceeded?

  • A traffic policing
  • B weighted random early detection
  • C traffic prioritization
  • D traffic shaping
Explanation

Traffic shaping is the QoS mechanism that temporarily stores packets exceeding the configured rate in a buffer and transmits them later so output stays within the defined bandwidth. By contrast, traffic policing typically drops or marks traffic that exceeds the rate, while WRED selectively drops packets before a queue is full, and prioritization only affects servicing order.
