What does Quality of Service (QoS) typically enhance in a network?

Quality of Service (QoS) is primarily designed to enhance network traffic management. It involves implementing various techniques to prioritize specific types of data traffic over others, ensuring that critical applications receive the necessary bandwidth and low latency required for optimal performance. This is especially important in environments where there are multiple applications competing for limited network resources, such as voice over IP (VoIP) or video conferencing.

By effectively managing the network traffic, QoS can minimize delays, reduce packet loss, and provide a more consistent and reliable experience for users. Prioritization techniques, such as traffic shaping and resource reservation, are integral parts of QoS that help maintain the quality of service for applications that are sensitive to latency and bandwidth fluctuations.

The other choices, while relevant to network security and performance, do not encapsulate the primary function of QoS in the way that traffic management does.
