Which configuration option is used to manage quality of service in RouterOS?

The configuration option that is used to manage quality of service (QoS) in RouterOS is queue types. Queue types define the behavior of traffic passing through the router, allowing you to control the prioritization and management of bandwidth usage as per your requirements.

In RouterOS, queue types help in classifying traffic and applying policies based on specific rules. They allow you to set parameters such as maximum bandwidth, limits, and priorities for different types of traffic, which is essential for effective QoS management. By configuring the appropriate queue types, you can ensure that critical applications receive priority over less critical traffic, thus optimizing network performance and user experience.

Other options, while related to QoS, play supporting roles in traffic management. For example, traffic shaping and packet marking are techniques used to implement QoS policies effectively but rely on queue types for their application. Bandwidth management encompasses a broader strategy, which includes using queue types along with other methods to regulate bandwidth usage throughout the network.
