Queues will turn Yellow at what percentage of utilization?

• A. 10-20%
• B. 50-75%
• C. 80-90%
• D. 25-45%

Answer: (B)

Queue utilization indicators in MikroTik RouterOS use color to signal how full the queue is. Yellow appears when utilization is roughly 50–75% of the configured limit, serving as a warning before the limit is reached. This helps you spot rising load early and take action before congestion occurs. For example, with a 10 Mbps limit, yellow shows around 5–7.5 Mbps. Below 50% is typically green (healthy), and higher levels (around 80–90% or more) are usually shown in red or another alert color indicating high risk of congestion.
