HP HP0-Y50 Online Questions & Answers

• Question 91:

  What correctly describes one trend that is changing how network architects must design the data center network infrastructure?

  A. Applications are drawing on more and more locally stored data, which causes customers to favor blade servers and blade enclosures
  B. Applications are considering on single, highly available mainframes, driving the need for 10G connections to the server edge
  C. Applications are increasingly virtualized, which requires architects to implement routing at the access layer to segment each rack into its own VLAN
  D. Applications are scaling out across multiple servers, increasing communications between servers distributed across the data center
  D. Applications are scaling out across multiple servers, increasing communications between servers distributed across the data center

• Question 92:

  An implementation plan should include an agreed-on time for the final rollback decision. What should this decision be scheduled?

  A. After the cutover to the new solution and the first set of validation tests and just before the user acceptance tests (UATs)
  B. after the first steps of the rollback plan have been implemented, about ten minutes before the end of the maintenance window
  C. just before the point of no return, which is calculated by subtracting the rollback time from the end of the maintenance window
  D. ten minutes before the end of the maintenance window or one hour into the implementation, whichever occur first
  C. just before the point of no return, which is calculated by subtracting the rollback time from the end of the maintenance window

• Question 93:

  Refer to the exhibit.

  

  The exhibit shows a proposed design for a data center network infrastructure. The exhibit shows two racks for simplicity. The data center will actually include more racks.

  The customer has these key requirements:

  The customer can scale any application and easily install new hardware that supports that application

  The network supports vMotion for live migration of virtual machine (VMs)

  How should the network architect change the proposed design to meet the customer requirements?

  A. Replace the rack servers with blade enclosures
  B. Add more links between the servers and the access layer
  C. Remove routing from the access layer and extend VLANs to multiple racks
  D. Add a distribution layer between the access layer and the core
  A. Replace the rack servers with blade enclosures

• Question 94:

  After analyzing a hospital's applications, the network architect identifies two life-critical applications. What is the availability requirement for a life-critical application?

  A. 99%
  B. 99.9%
  C. 99.99%
  D. 99.999%
  D. 99.999%

• Question 95:

  A network architect is choosing core switches for an enterprise data center. One potential model has a CLOS hardware architecture, and the other model has a cross-bar architecture. Which customer requirement would cause the network architect to select switches with CLOS architecture?

  A. The customer has a multi-tenant data center, which needs to use Virtual Routing and Forwarding (VRF) to segment the network
  B. The customer needs a highly-available core, which is best delivered with Intelligent Resilient Framework (IRF)
  C. The customer has relatively small data center and does not have the budget to invest in high performance
  D. The customer is planning to scale bandwidth up to 40G/100G in the next several years
  B. The customer needs a highly-available core, which is best delivered with Intelligent Resilient Framework (IRF)

• Question 96:

  A customer requires high availability for wireless services at branches. The customer also wants to centralize management and traffic distribution as much as possible. What should the architect suggest?

  A. Controlling branch APs with one or more HP 7500/10500 20G Wired-WLAN at the main office and enabling remote-AP features
  B. Controlling branch APs with a cluster of HP 830 Unified Wired-WLAN switches, one of which is deployed at the main office and one of which is deployed at the branch
  C. Deploying the APs without a controller but managing them with HP Intelligent Management Center (IMC) Wireless Services Manager (WSM)
  D. Controlling Branch APs with two HP 830 Unified Wired-WLAN switches, which are deployed at the main office
  D. Controlling Branch APs with two HP 830 Unified Wired-WLAN switches, which are deployed at the main office

• Question 97:

  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
  A. HP MSR3000 Routers
  E. HP 5400 zl Switches

• Question 98:

  A network architect is working with a customer to implement a new network design. The network architect has learned that the company has a legacy application hosted on a number of legacy servers. The legacy application must remain intact and after the new network implementation. As the company plans to continue using it indefinitely.

  With which stakeholder should the network architect discuss the technical detail of the legacy system and any challenges or specifics about maintaining interoperability?

  A. Chief Executive officer (CEO)
  B. Network Architect or Planning Engineer
  C. Chief Information Officer (CIO) or Voice President (VP)/ Director of IT
  D. Chief Financial Officer (CFO) or Voice President (VP)/ Director of Finance
  B. Network Architect or Planning Engineer

• Question 99:

  

  A customer has an existing solution, which is shown in Exhibit 1. (The solution actually includes more access layer switches than shown.) In the existing solution, each access layer switch routes traffic.

  A network architect is proposing the HP FlexCampus solution shown in Exhibit 2. In this proposed solution, the core Intelligent Resilient Framework (IRF) virtual switch routes traffic but the access layer switches do not. The customer links that

  in the existing solution if an access layer uplink fails, failover occurs in less than a second.

  The customer also likes that the existing solution does not require Virtual Router Redundancy Protocol (VRRP).

  What should the architect tell the customer about the benefits of the proposed solution?

  A. Although the solution offers slower failover for the access layer uplinks, it is simpler and eliminates VRRP.
  B. STP eliminates the loops on the access layer uplinks and handles failover for them, which speeds convergence.
  C. Failover for an access layer uplink occurs in milliseconds, and router redundancy does not require VRRP.
  D. IRF handles loop elimination and link failover, which lets VRRP handle router redundancy more efficiently.
  C. Failover for an access layer uplink occurs in milliseconds, and router redundancy does not require VRRP.
