Question
A network architect has created a quality of service (QoS) for an HP 5900 Series switch that uses four traffic classes. Class of Service (CoS) 5 for voice traffic. CoS 4 for Video traffic. And CoS 0 for everything else. The switch ports implement strict priority (SP) queuing. What would be an advantage of enabling weighted fair queuing (WFQ) instead of SP?
Options
- AWhen congestion occurs, the port will randomly drop traffic in the CoS 3 and CoS 0 queues,
- BThe architect can ensure that voice traffic is always forwarded before bandwidth intensive video
- CThe architect can guarantee specific bandwidth to each class but prevent video an SAP
- DWhen congestion occurs, the port will buffer traffic in lower priority queues rather than drop it
