How does QoS traffic shaping alleviate network congestion?
QoS traffic shaping alleviates network congestion by buffering and queuing packets that exceed the committed rate. This helps smooth out bursts in traffic, allowing for more consistent data flow and preventing packet loss. Traffic shaping ensures that packets are held in a queue and sent out in a controlled manner when the network has the capacity to handle them. This is different from traffic policing, which would drop packets that exceed a certain bitrate, and other mechanisms such as packet fragmentation or random packet dropping from lower priority queues.
B is the accepted answer. traffic shaping support packet buffer while traffic policing support packet drop.
B is Correct. During congestion, traffic shaping buffers and queues packets above the committed rate. Answer A describes Policing dropping packets exceeding a certain bitrate. Answer C is describing packet fragmentation when the router receives an IP packet above 1500 bytes. Answer D is sort of describing Random Early Detection (RED) which is a congestion avoidance mechanism that randomly drops packets from RED-enabled interfaces or queues during periods of high congestion. RED tells the packet source to decrease its transmission rate.

During shaping phase, it uses queues to force some traffic to wait (buffered traffic) to avoid congestion
traffic shaping buffers whereas policing drops the traffic
