The braindumps of HP0-791 exam

The braindumps of HP0-791 exam:
1. A converged network ________________.A. can transmit voice, video, and data over a single infrastructureB. deploys circuit-switching instead of packet-switchingC. can serve more users than a conventional IP networkD. features an edge-oriented architectureAnswer: A
2. Ethernet and IP are the fundamental technologies for converged networks because they ___________. Select TWO.A. offer mature standardsB. tolerate high packet lossC. are widely deployedD. offer high levels of securityE. aren't disrupted by power outagesAnswer: AC
3. How does the ProCurve Adaptive EDGE Architecture support convergence?A. by enhancing edge compression of video streamsB. by ensuring that traffic is prioritized at the edge of the networkC. by translating analog signals to digital signals at the edge of the networkD. by supporting a variety of Layer 3 protocols at the edge and in the core of the networkAnswer: B
4. In a converged network, what does video traffic require in comparison to voice traffic?A. less delayB. higher priorityC. more bandwidthD. more expensive cablingAnswer: C
5. What is the measurable degree to which an IT staff can successfully guarantee the predictable behavior of network services?A. Type of Service (ToS)B. Class of Service (CoS)C. Quality of Service (QoS)D. Guarantee of Service (GoS)Answer: C
6. In comparison to streaming video traffic, voice traffic is typically more ______________.A. difficult to routeB. insensitive to jitterC. sensitive to delayD. bandwidth-intensiveAnswer: C
7. What is IP Type of Service (ToS) an example of?A. hard QoSB. soft QoSC. continual QoSD. virtual QoSAnswer: B
8. A user of a new VoIP infrastructure reports that she unintentionally speaks at the same time as the person on the other end of the line. This condition could be caused by excessive _____________.A. jitterB. delayC. echoD. packet collisionsAnswer: B
9. Why does network congestion often cause more network congestion?A. QoS settings require switches to retransmit all real-time traffic.B. TCP applications request retransmission of dropped packets.C. 802.1p priorities are ignored after congestion reaches a user-defined threshold.D. RSVP routers allocate more bandwidth to UDP applications.Answer: B
10. You are planning a network upgrade at a small company. During a meeting, you learn that the customer will install VoIP telephones that set Layer 2 and Layer 3 priority markers for all voice traffic. The VoIP traffic will not cross any WAN links. To support these phones, the customer's new ProCurve 5300xl series switches will require ___________________.A. rate limiting on all ports that support VoIP phonesB. GMB settings for voice trafficC. an IEEE 802.1p-to-DSCP map for voice trafficD. no QoS configuration changesAnswer: D
