Question
What is a characteristic of traffic shaping?
Options
- Adrops out-of-profile packets
- Bcauses TCP retransmits when packets are dropped
- Ccan be applied in both traffic directions
- Dqueues out-of-profile packets until the buffer is full
Explanation
Traffic shaping is a quality of service mechanism that smooths out traffic flow by queuing 'out-of-profile' packets and delaying their transmission until they conform to the configured rate.
Common mistakes.
- A. Dropping out-of-profile packets is characteristic of traffic policing, which immediately discards non-compliant traffic.
- B. While traffic policing can cause TCP retransmits by dropping packets, traffic shaping aims to prevent drops by buffering, thus avoiding unnecessary retransmits.
- C. While QoS mechanisms can often be applied in both traffic directions, the defining characteristic of traffic shaping is its buffering action, differentiating it from policing.
