What upload/download speed will a client at 10.10.0.33 obtain when Simple Queue number 0 defines 2M and Simple Queue number 1 defines 4M?

In MikroTik's Simple Queues, each queue can set limits on bandwidth for specific IP addresses. If a client, such as the one at the IP address 10.10.0.33, is subject to multiple queues, the behavior of the queues determines which limit is applied.

In this scenario, the first Simple Queue is set to 2M, and the second Simple Queue is set to 4M. When a client is assigned to more than one queue, MikroTik applies the lowest limit from the queues for that client. In this case, the lowest limit is from the queue that defines the bandwidth at 2M.

This means the client at 10.10.0.33 will be restricted to an upload/download speed of 2M, despite the existence of a higher limit (4M) in the other queue. Therefore, the correct answer indicates that the client's upload/download speed is determined by the lower of the two configured queues, which is 2M.
