If the Max Limit is set to 10M, what would be the recommended Burst Threshold?

• A. 10M
• B. 5M (one half)
• C. 2M
• D. 15M

Answer: (B)

Bursting lets a queue exceed its steady rate for short periods to handle quick traffic spikes. The Burst threshold is the amount of data that must be transmitted at the normal rate before a burst can start; once that point is reached, the traffic can briefly rise toward the Burst limit.

With a Max Limit of 10M, a practical default is about half of that, so 5M. This provides room for short spikes without letting bursts run away and saturate the link. Setting it to 10M would allow bursts too easily, 2M would make bursts too rare, and 15M is invalid since it’s above the configured maximum.
