The correct answer is B. 4-class QoS strategy. A 4-class QoS strategy uses the minimum number of classes required to provide differentiated services, making it resource-efficient and scalable for large networks like ISP backbones, while still supporting premium service markings such as CS5.
Question
An ISP is going to offer premium broadcast services to its clients. Services will be marked with CS5 and will be using 10% of the link bandwidth. All links are at 10 Gbps in the backbone and 1 Gbps toward end clients with GPON technology. The ISP wants to use the minimum required resources on the network nodes and for it to be easily scalable. Which QoS strategy model must the ISP select to offer the premium service?
