Question:
How does QoS traffic shaping alleviate network congestion?

  • A. It drops packets when traffic exceeds a certain bitrate.
  • B. It buffers and queue packets above the committed rate.
  • C. It fragments large packets and queues them for delivery.
  • D. It drops packets randomly from lower priority queues.
