Explanation

Quality of service (QoS) is a mechanism that is designed to give priority to different applications, users, or data to provide a specific level of performance. It is often used in networks to prioritize certain types of network traffic. It is not designed to block traffic, per se, but to give certain types of traffic a lower or higher priority than others. This is least likely to counter a denial of service
