Which QoS action buffers traffic to conform to a rate before transmission?

Explanation:
Shaping is the QoS action that buffers traffic to conform to a rate before transmission. It uses a queue to hold excess packets when the outbound rate is exceeded and then releases them at a steady, configured speed. This smooths bursts, reduces downstream congestion, and helps meet a target rate, though it adds some latency. Policing enforces the rate at the entry point by dropping or re-marking packets that exceed the limit, without the same buffering and smoothing. Dropping simply discards packets, and marking only changes priority without altering the transmission rate. So buffering to conform before sending is the hallmark of shaping.
