Which technique does traffic shaping use to manage excess traffic?

• A. Packet marking
• B. Queue caching
• C. Dropping packets
• D. Immediate truncation

Answer: (B)

Traffic shaping is a network management technique designed to control the amount and the timing of traffic sent into a network. The primary goal is to ensure that network resources are used efficiently and to provide a consistent quality of service (QoS) for certain types of traffic. Queue caching, while not a commonly recognized term in the context of traffic shaping, suggests an approach where packets are queued for later processing rather than being sent immediately, enabling better management of bandwidth. In the context of traffic shaping, the correct understanding revolves around the idea of temporarily storing packets in a queue, allowing the network to control the flow rate of data being transmitted. By managing how packets are queued and transmitted, traffic shaping can help prevent network congestion and ensure that high-priority traffic has the necessary bandwidth. Other techniques that might be associated with managing excess traffic, such as packet marking or dropping packets, do indeed play roles in traffic management but are not illustrative of traffic shaping principles. Packet marking often classifies packets for QoS purposes, while dropping packets can be a last resort during congestion. Immediate truncation refers to cutting off data transmission instantly, which is generally not aligned with the goals of traffic shaping, which focuses more on smoothing and controlling traffic flow rather than abruptly cutting it off.
