Valid Class for 8-Class QoS Strategy

C.

The 8-Class QoS (Quality of Service) strategy is a way to prioritize and manage network traffic in a VoIP (Voice over IP) network. This strategy divides network traffic into eight different classes, each with its own priority level, marking, and queuing behavior.

Out of the options provided, "Assured Forwarding" (AF) and "Real-Time Interactive" (RTI) are valid classes included in the 8-Class QoS strategy in a VoIP network.

Assured Forwarding (AF) is a set of four classes (AF1 through AF4), each with its own priority level and drop probability. These classes are used to provide a differentiated treatment for network traffic that requires different levels of priority and service quality. For example, AF1 can be used for network traffic that is less time-sensitive, while AF4 can be used for network traffic that requires the highest priority and the lowest drop probability.

Real-Time Interactive (RTI) is a class used for real-time applications such as VoIP, video conferencing, and other interactive applications. This class has a higher priority than other classes, and network traffic in this class is typically given the lowest latency and the highest bandwidth to ensure a smooth user experience.

Broadcast Video and Multimedia Conferencing are not part of the 8-Class QoS strategy in a VoIP network. Broadcast Video is typically used for one-to-many video streaming applications, such as live broadcasts or webcasts, and is not related to VoIP. Multimedia Conferencing, on the other hand, is a broad category that can include various types of network traffic, including VoIP, video conferencing, screen sharing, and more. However, it is not a specific class in the 8-Class QoS strategy.
