Question 51.
A network administrator must configure a ProCurve 5304xl switch to assign traffic entering the switch through VLAN 125 to a higher priority queue. Currently, the IEEE 802.1p priority for this VLAN is 4. In the VLAN 125 context, the administrator enters qos priority 5.

Answer: A, B, C
Question 62.
Which statement is true about policing traffic conditioners in IP QoS?
A. Policing reorders transmit queues to offer priority service to specific traffic flows.
B. Policing utilizes buffers to delay excessive traffic when the flow is higher than expected.
C. Policing techniques monitor network traffic loads in an effort to anticipate and avoid
congestion.
D. Policing allows the network administrators to traffic engineer paths through the network for
application flows.
E. Policing is the ability to control bursts and conform traffic to ensure certain traffic types receive
specified amounts of bandwidth.
Answer: C
Question 63.
What are two important benefits of applying QoS to IP networks? (Choose two)
A. QoS manages packet loss during periods of bursty congestion.
B. QoS allows network managers to control usage patterns of network applications.
C. QoS can solve traffic problems on low bandwidth, high-latency, high-loss WAN links.
D. QoS facilitates the integration of differing traffic types such as voice, video, and data into a
single infrastructure.
E. QoS can provide performance enhancements for commercial application issues such as server
sizing and tuning.
