If a client's network allows defined traffic to reach its destination based on priority, what is enabled on their network?

When a client's network allows defined traffic to reach its destination based on priority, it indicates that Quality Of Service (QoS) is enabled on their network. QoS is a networking concept that ensures the performance of critical applications by prioritizing certain types of traffic over others. For instance, time-sensitive applications like VoIP and video conferencing require low latency and high reliability, thus they are often prioritized in the network's traffic management strategy.

By implementing QoS, network administrators can set rules that designate which types of traffic should take precedence during times of congestion, ensuring that important applications receive the necessary bandwidth and low delay while less critical traffic may experience a lower priority. This capability is essential in environments where multiple types of data are transmitted simultaneously, helping to maintain an optimal user experience for high-priority applications.

While Voice Over IP (VoIP) and Video On Demand (VOD) may benefit from QoS, they are not directly responsible for traffic prioritization. Access Control Lists (ACLs) are used for controlling access to network resources and do not inherently prioritize traffic based on its type or importance.
