• Question 81:

  Refer to the exhibit.

  

  The exhibit shows a network with HP 3500 yl Series switches at the access layer and HP 8206 zl switches at the core. The customer with this solution has logged several support calls, which were eventually tracked down to spanning tree issues. How can a network architect adjust the solution to prevent the issue in the failure?

  A. Implement BPDU filters on the switch-to-switch links and loop protection edge ports

  B. Connect three or four 3500 y1 switches together in a group. Establish a distributed trunk between two switches in each group and the core switches

  D. Configure distributed Trunking on the two 8200 zl switches at the core. Create a distributed trunk between the core switches and each 3500 yl switch

  Correct Answer: D

• Question 82:

  The exhibit shows the topology for an enterprise customer LAN with an on-site data center.

Therefore the customer has requested a backup that extends directly between the IRF group and the data center core. All of the VLAN interfaces and routed link aggregations that are shown implement Open Shortest Path First (OSPF) in a single area.

  Which tasks should the network architect complete to ensure that the HP 5500 IRF group selects the correct path to the data center during (Select two).

  A. Change the reference bandwidth to 80000 on all routing devices.

  B. Configure the VLAN 101 interfaces as silent interfaces.

  C. Change the reference bandwidth on the VLAN 101 interfaces to 1000.

  D. Set the cost on the VLAN 100 interfaces to 2Set the cost for the VLAN 101 interfaces to 80.

  E. Change the reference bandwidth on the VLAN 100 interfaces to 20000.

  Correct Answer: CE

• Question 83:

  A service must be available 24x7. It also requires 99.999% availability. How much total downtime can the service tolerate in one year?

  A. About 5 seconds

  B. About 5 minutes

  C. About 50 minutes

  D. About 5 hours

  Correct Answer: B

• Question 84:

  A customer is seeking an upgrade for their campus LAN network. Currently, the customer has access layer switches that support 18.10/100/1000 Mbps ports and one Gigabit uplink. The customer wants better performance in the upgrade but also wants to minimize costs.

  The network architect has used the Network Traffic Analyzer (NTA) for Intelligent Management Center (IMC) to collect information about the access layer uplinks. These are the results:

  For switches on Floor1, the peak utilization is 650 Mbps on a Gigabit uplink. On most days, the utilization peaks at about 400 Mbps. Peaks usually occur briefly. For switches on Floo2, the peak utilization is 800 Mbps on a Gigabit Uplink.

  During active periods, the utilization often remain near 800.

  What is most appropriate plan for oversubscription in the new access layer? (For this question, think only about oversubscription and not customer needs for redundancy)

  A. 48 1 on floor 1 and 24 1 on floor 2

  B. 24.1 on floor 1 and 4.1 on floor 2

  C. 48 1 in all locations

  D. 24 1 in all locations

  Correct Answer: A

• Question 85:

  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

  Correct Answer: D

• Question 86:

  Refer to the exhibit.

  

  The exhibit shows the topology for a network with 30 access layer switches (only two are shown). Every switch-to-switch link is a Gigabit link. Every virtual local area network (VLAN) interface runs Open Shortest Path First (OSPF) and has

  the IP address shows in the exhibit. The interface settings are at the defaults.

  The access layer switches support more VLANs not shown in the exhibit and also run Multiple Spanning Tree Protocol (MSTP) as a protection against loops.

  What is one recommendation for enhancing convergence time and resiliency for this solution?

  A. Add a BPDU filter to the VLAN interfaces shown in the exhibit

  B. Lower the cost of the VLAN interfaces to reflect the high speed of the links

  C. Place all the switch-to-switch links in the same VLAN

  D. Raise the OSPF timers on the VLAN interfaces

  Correct Answer: A

• Question 87:

  If a network architect is planning a secure device management policy, why would administrators need to generate SSH keys on network infrastructure devices?

  A. To authenticate managers with a more secure method than passwords

  B. To encrypt management traffic and also authenticate managers with asymmetric

  C. To authenticate managers and assign them privileges according to their identity

  D. To encrypt management traffic related to the CLI

  Correct Answer: D

• Question 88:

  When does an architect need to plan fast roaming for the wireless solution?

  A. When wireless devices use 802.11n and their WLAN enforces WEP or WPA encryption

  B. When wireless devices use voice and real-time applications, and their WLAN enforces WEP or WPA encryption

  C. When wireless devices use 802 11n and associate with APs that support both 24 GHz and 5GHz with band steering

  D. When wireless devices use voice and real-time applications, and their WLAN enforces Wi-Fi Protected Access (WPA)

  Correct Answer: D

• Question 89:

  Refer to the exhibit.

  

  A network architect has planned redundant links as shown in the exhibit. What should the network architect do to ensure that the redundant link design is truly resilient?

  A. Implement the features such as link aggregation, backplane stacking, and intelligent Resilient Framework (IRF)

  B. Add another link between the Layer 2 switches and the core so that up to the two links can fail

  C. Implement a feature such as bidirectional forwarding detection (BFO) on each redundant link

  D. Make sure that each HP 10508 switch is configured as a root in one Multiple Spanning Tree Protocol (MSTP) instance

  Correct Answer: C
