HP HP ASE HP0-Y50 Questions & Answers

• Question 31:

  A network architect is planning an update of the server access layer in a data center. Currently, the access layer switches have 10G links to distribution layer switches. In the new solution, HP 5930 Switches act as top of rack (ToR) switches with 40G links to core switches.

  Which factor must the network architect consider when designing solution?

  A. Whether the data center cabling provides enough fiber strands to the racks to support the 40G links

  B. Whether the new switches 40G transceivers are on the chassis front or back, the transceivers must be on the same side as servers air outtakes

  C. Whether the servers connecting to the new switches use Ethernet Virtual Bridging (EVB)/Virtual Ethernet Port Aggregate (VEPA), which is not compatible with 40G

  D. Whether the servers connecting to the new switches have NICs that support Converged Enhanced Ethernet (CEE)

  Correct Answer: A

• Question 32:

  A customer plans to connect 40 Voice over IP (VoIP) phones and 8 security cameras to a switch:

  The VoIP phones are Class 2 PoE devices and require a maximum of 45W (draw a maximum of 5w)

  The security cameras are Class 4 PoE+ devices and require a maximum of 17W (draw a maximum of 20 W)

  The network architect is proposing an HP 5500-48G-PoE switch, which supports PoE and PoE+ and has a PoE power budget of 370W

  The customer and architect agree on the class form of power allocation

  What else does the solution require?

  A. A management module that is PoE+ capable

  B. A redundant power supply for the switch that enhances the PoE/PoE+ budget

  C. A power converter that enables the switch to provide PoE and PoE+ power at the same time

  D. A 208-220V input power service

  Correct Answer: A

• Question 33:

  A network architect is using the Network Traffic Analyzer (NTA) module for HP Intelligent Management Center (MC) to evaluate traffic patterns in a campus LAN environment. The network architect hopes to use this information to determine whether the current oversubscription is working well or whether the new plan to have less oversubscription.

  What will provide the most useful information for this decision?

  A. The peak utilization on uplinks

  B. The sum of the average utilization on user edge ports

  C. The peak utilization on randomly-selected user edge ports

  D. The average utilization on uplinks

  Correct Answer: A

• Question 34:

  A. HP MSR3000 Routers

  B. HP HSR6800 Routers

  C. HP 7500 Switches

  D. Hp 11900 Switches

  E. HP 5400 z\ Switches

  Correct Answer: AE

• Question 35:

  Organizations can deploy off-the-shelf, virtualized application 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 zl Switches

  Correct Answer: AE

• Question 36:

  The customer plans to connect 40 Voice over IP (VoIP) phones and 8 security cameras to a switch:

  The VoIP phones are Class 2 devices and require a maximum of 4.5W (draw 5w) The security cameras are Class 4 devices and require a maximum of 17W (draw 20W) The network architect is proposinga switch that supports PoE and PoE + and has a PoEPower budget of 370W.

  The architect proposes the usage from of power allocation. What are the advantages and disadvantages of this proposal?

  A. It allows the switch to run at a lower temperature, saving power and cooling costs, but it decreases the performance for the phones.

  B. It allows the switch to connect to the PoE and PoE+ devices on cheaper copper cable, but it limits the distance between the devices.

  C. It allows the switch to connect to the PoE and PoE + devices at the same time, but the customer must purchase a redundant power supply.

  D. It allows the switch to support the PoE requirements without a redundant power supply, but power might be oversubscribed if conditions change.

  Correct Answer: D

• Question 37:

  Which two requirements of a modern data center make Spanning Tree Protocol (STP) and other traditional loop elimination protocols for that environment?

  A. Requirement to implement routing clustering virtual machines

  B. Need to consolidate traffic on a single path thorough the network

  C. Greater reliance on direct attached storage

  D. Need for faster convergence times

  E. Need to support delay-sensitive applications

  Correct Answer: BE

• Question 38:

  A customer is deploying a mobility solution. The IT staff is not experienced in troubleshooting issues with interference and radio frequency (RF) design, and the customer is worried that the wireless connections will not be stable or will not perform well.

  Which feature of HP unified Wired-WLAN solutions addresses this customer concern?

  A. Hot access controller (AC) backup

  B. Wi-Fi Clear Connect integrated intrusion prevention system (IPS)

  C. Remote-AP capabilities for branch offices

  D. Wi-Fi Clear Connect radio resource management (RRM)

  Correct Answer: D

• Question 39:

  Refer to the exhibit.

  

  A network architect is designing the logical topology for a campus LAN networking solution. The customer requires support for 2400 edge ports, which is provided by 10 intelligent Resilient Framework (IRF) groups at the access layer. This customer does not have a wireless network nor anticipants adding one in the next two years. However, the customer does want to authenticate users with 802.1X and use the network RADIUS server to divide users from different groups into different VLANs. The customer has three user groups, each of which includes between 600 and 900 users.

  Additionally, the customer understands that the RADIUS server will require several policies but wants to keep these policies as simple and easy to maintain as possible.

  How can the network architect ensure that the solution meets the customer needs and also follows best practice?

  A. Assign a /23 subnet to each VLAN so that the VLAN can accommodate the required number of users, even if users connect multiple devices

  B. Plan a different VLAN ID and subnet address for each user group on each access layer IRF group. Either core or access layer routing will work for this solution

  C. Use access layer routing. Assign a different subnet to VLAN2 on one access layer IRF group then the VLAN2 on the another access layer group

  D. Plan a solution for designing dissolvable agents to the endpoints so that they can complete 802.1X authentication seamlessly

  Correct Answer: B

• Question 40:

  A network architect is designing a redundancy solution for a customer and has learned that there is a single link between two critical network components. During the past 4000 hours of operation, the link has failed twice. The customer estimates that each failure has taken two hours to resolve.

  Given this information, what is the availability that this link currently provides?

  A. Less than 99.99%

  B. 99.9%

  C. 99.99%

  D. 99.999%

  Correct Answer: B
