HP HP ASE HP0-Y50 Questions & Answers

• Question 71:

  Customer has a virtualized data center Microsoft Hyper-V Windows Server 2012. The customer has provided this information about the Ms:

  Each host has a network (Hyper-V virtual switch) that supports VM productions traffic and owns two server 10G NICs.

  Each host has a network (Hyper-V virtual switch) that supports management traffic to the parent partition and owns two server Gigabit NICs. Each rack, the network architect plans to deploy two HP 5920 Series switches, acting as an

  Intelligent Resilient Framework (IRF) switch.

  Which additional information does the architect need in order to plan the connections to each host?

  A. Whether the virtual switches use sFlow or Net Stream to load balance traffic over the NICs

  B. Whether the virtual switches use Virtual Ethernet Port Aggregator (VEPA) VLAN tagging

  C. Whether the virtual switches use generic or dynamic NIC teaming (Link Aggregation Control [(LACP)] and their hashing method

  D. Whether the virtual switches support standard Spanning Tree Protocol (STP) or Cisco Per-VLAN Spanning Tree Protocol Plus (PVST+)

  Correct Answer: C

• Question 72:

  A. Enterprise-wide VoIP solution

  B. Centralized database servers hosting a rich-media client-server application

  C. External customer-facing rich-media web application

  D. Enterprise-wide collaboration using video and messaging

  Correct Answer: A

• Question 73:

  A network architect has designed a two-tier topology for the campus LAN and is planning to implement routing at the core. Which requirement might cause the network architect to consider implementing routing at the access layer?

  A. Employees in different VLANs need to use collaboration applications to share high- resolution graphic files

  B. The solution must support an isolated VLAN for wired guest devices

  C. Employees need to be placed in dynamic VLANs, assigned by a RADIUS server in identity, so that network managers can manage the solution more easily

  D. The customer has an HP Unified Wired-WLAN solution, and wireless users need to roam seamlessly across the site

  Correct Answer: A

• Question 74:

  An employer takes the company laptops offsite and connects it to an insecure network. A hacker is able to deploy a malware application to the laptop. The employer takes the laptop back to the office, where the malware uses the credentials of the employee to eavesdrop and to implement denial of service (DoS) attacks.

  Which security solution would help prevent this type of attack?

  A. MAC lockdown

  B. A dynamic VPN (DVPN)

  C. Port-based security with 802.1X

  D. Endpoint integrity

  Correct Answer: D

• Question 75:

  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)

  Correct Answer: B

• Question 76:

  

  The customer wants to assign users to VLANs dynamically based on their Windows group. The company Windows Network Policy server provide the assignments. Each of the Windows groups includes between 100 to 600 users. Which issue does the architect need to resolve?

  A. The proposed dynamic VLANs have too many potential users for the proposed subnets.

  B. The plan for the edge ports is incorrect they should be trunk ports that support multiple VLANs.

  C. The switch-to-switch links should not carry so many VLANs.

  D. The proposed switches do not accept dynamic VLAN assignments from Windows NPS servers.

  Correct Answer: A

• Question 77:

  An architect is planning an HP Wired-WLAN solution for an office with approximately 4000 users. The solution will have 256 MSM460 APs WLAN controllers. Users must be able to roam seamlessly around the site.

  Which strategy meets these needs?

  A. Assign users to different VLANs based on the APs to which they connect, and distribute traffic centrally at the controller.

  B. Assign users to different VLANs based on the APs to which they connect, and distribute traffic locally at the AP.

  C. Assign all users to the same VLAN, and distribute traffic locally at the AP.

  D. Assign all users to the same VLAN and distribute traffic centrally at the controller.

  Correct Answer: D

• Question 78:

  Which description best characterizes current trends in deploying services for an enterprise solution?

  A. Companies are transforming their campus LAN and data counters into one large Layer 2 network.

  B. Companies are connecting multiple suites together but distributing services to each site to increase resiliency and responsiveness

  C. Companies are moving services out of the private cloud into more responsive pods that are distributed throughout the campus LAN

  D. Companies are centralising services in a consolidated data center or even a highly scalable private cloud

  Correct Answer: D

• Question 79:

  A customer requires high availability, so the network architect is planning two area border (ABRs) for each non-backbone area in the Open Shortest Path First (OSPF) solution. What ensures a loop-free routing environment that meets the customer needs?

  A. All ABRs have at least one interface in area 0, and that interface has an IP address that is outside of the range of any summaries for area 0

  B. Each ABR in an area advertises the same summary routes for the area, and each ABR has a null route that matches those summaries

  C. Only one ABR advertise a summary route for each area. For areas with multiple ABRs, each area can include two summaries ranges, and each ABR is configured with one of those ranges

  D. All ABRs in an area apply consistent path costs for their summary routes

  Correct Answer: A

• Question 80:

  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

  Correct Answer: C
