There is a saturated link that has traffic shaping configured. How is incoming traffic processed?
The correct answer is A. Excess traffic is queued for later transmission. Traffic shaping buffers (queues) excess traffic and releases it at a controlled rate to conform to the configured bandwidth limit. This smooths bursty traffic by holding packets in a queue rather than discarding them. This is the key distinction between traffic shaping and…

Explanation
Traffic shaping buffers (queues) excess traffic and releases it at a controlled rate to conform to the configured bandwidth limit. This smooths bursty traffic by holding packets in a queue rather than discarding them. This is the key distinction between traffic shaping and traffic policing: policing drops excess traffic (Choice B), while shaping delays it. Compression (Choice C) is unrelated to shaping behavior. Choice D describes a timed queue-then-drop mechanism that is characteristic of policing with a burst allowance, not shaping. With shaping, packets remain queued until bandwidth becomes available.
