Architecting HP FlexNetwork Solutions: HP0-Y50

HOTSPOT

Match the customer need with the HP FlexFabric technology that meets the need.

Hot Area:

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. The architect can guarantee specific bandwidth to each class but prevent video an SAP applications from starving out other applications entirely

D. When congestion occurs, the port will buffer traffic in lower priority queues rather than drop it immediately as it does with SP queuing

Which description best characterizes current trends in deploying services for an enterprise solution?

A. Companies are transforming their campus LAN and data counters into one large Layer 2 network.

B. Companies are connecting multiple suites together but distributing services to each site to increase resiliency and responsiveness

C. Companies are moving services out of the private cloud into more responsive pods that are distributed throughout the campus LAN

D. Companies are centralising services in a consolidated data center or even a highly scalable private cloud
