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?
A.
When congestion occurs, the port will randomly drop traffic in the CoS 3 and CoS 0 queues,
preventing TCP synchronization that increase congestion
B.
The architect can ensure that voice traffic is always forwarded before bandwidth intensive video
traffic
C. applications from starving out other applications entirely
The architect can guarantee specific bandwidth to each class but prevent video an SAP
D.
When congestion occurs, the port will buffer traffic in lower priority queues rather than drop it
immediately as it does with SP queuing
