HP HP0-Y50 Online Questions & Answers

• Question 81:

  A network architect is planning an intelligent Resilient Framework (IRF) group. What should the network architect implement to protect against a split IRF group?

  A. Distributed Trunking (DT)
  B. Virtual Router Redundancy Protocol (VRRP)
  C. Multi-Active Detections (MAD)
  D. Rapid Ring Protection Protocol (RRPP)
  C. Multi-Active Detections (MAD)

• Question 82:

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

• Question 83:

  Which benefit does In-Service Software Upgrades (ISSU) provide?

  A. Schedules and performs switch upgrades through HP Intelligent Management Center (IMC)
  B. Upgrades members of an IRF virtual switch one at a time to avoid services disruption
  C. Upgrades members of theIRF virtual switch simultaneously to ensure all members use the same software version
  D. Automatically checks for software updates on the HP Websites, downloads the new software, and upgrades the switches
  B. Upgrades members of an IRF virtual switch one at a time to avoid services disruption

• Question 84:

  A network architect is designing as a Multiple Spanning Tree Protocol (MSTP) solution for a network. The network architect plans to create 10 VLANs. The network architect also wants to ensure that the best paths are selected when interoperating with other spanning tree regional.

  Which guideline aids in ensuring best paths between regions?

  A. Place five VLANs in one MSTP instance and five in the other instance.
  B. Set up the correct priority on the switch that you want to be root in instance 0.
  C. Calculate the traffic load for each VLAN and then distribute them accordingly between each MSTP instance.
  D. Use the appropriate cost settings for links as specified in the IEEE 802.1t standard.
  C. Calculate the traffic load for each VLAN and then distribute them accordingly between each MSTP instance.

• Question 85:

  What best characterizes the current trend in branch office IT and networking solutions?

  A. Assignment of designated IT staff to branch offices
  B. Consolidation of traditional resources within the data center
  C. Increased reliance on wireless services to fill the bandwidth deficiency provided by traditional WAN links
  D. Moving away from Ethernet-based WAN links toward dedicatedT1/E1/J1 lines
  B. Consolidation of traditional resources within the data center

• Question 86:

  Organizations can deploy off-the-shelf, virtualized applications on some HP infrastructure devices Which devices support this capability? (Select two )

  A. HP MSR3000 Routers
  B. HP HSR6800 Routers
  C. HP 7500 Switches
  D. Hp 11900 Switches
  E. HP 5400 z\ Switches
  A. HP MSR3000 Routers
  E. HP 5400 z\ Switches

• Question 87:

  Refer to the exhibit.

  

  The exhibit shows how two NICs on a physical server connect to two HP 5820 switches. The server supports eight virtual machines (VMs) with VMware version 5.1. The VMware standard virtual switch is bound to NIC and NIC2. This switch implements source MAC load balancing for the NIC team.

  What is the proper configuration for ports 1/0/1 and 2/0/1?

  A. Place the ports in a bridge aggregation group that does not use LACP
  B. Place the ports in a bridge aggregation group that uses LACP
  C. Enable LACP on the individual ports
  D. Do not place the ports in a bridge aggregation group
  B. Place the ports in a bridge aggregation group that uses LACP

• Question 88:

  A customer has a virtualized data center with hosts that are managed by VMware vCenter. The network architect has proposed the HP Virtual Application Networks (VAN) Connection Manager (CM) and Resource Automation Manager (RAM) modules for HP Intelligent Management Center (IMC). The architect also proposed the HP 5900v switches and the proper server access layer products.

  Which technology must the access layer switches that connect to the virtualized servers support?

  A. Transparent Interconnection of Lots of Links (TRILL)
  B. Intelligent Resilient Framework (IRF)
  C. Ethernet Virtual Bridging (EVB)/Virtual Ethernet Port Aggregator (VEPA)
  D. Fiber Channel over Ethernet (FCoE)
  B. Intelligent Resilient Framework (IRF)

• Question 89:

  A network architect is choosing fabric module for an HP 10500 Series Switch. Which factors affect the choice?

  A. The environment in which the switch will be installed and the direction of the airflow
  B. The number of IPv4 and IPv6 routes that the switch must support in its routing table
  C. The type of I/O modules and whether full bandwidth must be supported on all ports at the same time
  D. The type of management modules and whether these modules operate in hot-standby mode
  C. The type of I/O modules and whether full bandwidth must be supported on all ports at the same time

• Question 90:

  A network architect has planned several validation tests and user acceptance tests (UATs) for a new HP solution. In order to ensure meaningful results, what is one step that the network should complete before implementing the new solution?

  A. Talk with key authentication to determine valid maintenance windows for the UATs
  B. Plan how long it will take to rollback the new solution of the tests indicate poor results
  C. Schedule a point of no return, after which results will not be accepted
  D. Run the same tests on the existing network solution
  D. Run the same tests on the existing network solution
