What policy prioritizes the flow of data for voice and video on a network?

The policy that prioritizes the flow of data for voice and video on a network is Quality of Service (QoS). QoS is essential in networking environments where different types of traffic need to be managed to ensure an optimal experience for end users, particularly for applications like VoIP (Voice over Internet Protocol) and video streaming, which are sensitive to delays, jitter, and packet loss.

QoS strategies involve prioritizing traffic types so that voice and video packets receive higher priority over less time-sensitive data, such as file downloads or web browsing. This prioritization helps to maintain the quality of real-time communications, providing a clear and uninterrupted experience. By classifying traffic and implementing mechanisms such as queuing, bandwidth reservation, and traffic shaping, QoS ensures that critical applications perform reliably even under heavy network load.

While the other options have their uses in network management, they do not specifically focus on prioritizing data for real-time communication like QoS does. Bandwidth Management pertains to controlling and allocating bandwidth across the network, but it does not inherently prioritize types of traffic. Network Access Control focuses on security and user permissions rather than traffic prioritization. Traffic Shaping is a technique used to control network traffic flow but is not solely responsible for the prioritization of
