Correct answer: to limit the bandwidth that a flow can use.
Why this is the answer
Traffic shaping's primary purpose is to control the rate at which data is transmitted, effectively limiting the bandwidth a flow can consume. This prevents a single flow from monopolizing network resources and ensures a more predictable network performance. While shaping can indirectly mitigate delays by preventing congestion, its core function is rate limiting. Marking mechanisms identify flows but don't control their rate. Fair queuing is a scheduling mechanism that distributes bandwidth among buffered flows, but shaping actively enforces a maximum rate.
