HP HP Certifications HP0-Y50 Questions & Answers

• Question 51:

  The customer has a virtualized data center. The virtual hosts use virtual distributed switches with multiple redundant uplinks and these update control Protocol (LACP).

  Which technology available in HP switches enhances high availability in this environment?

  A. Fiber Channel over Ethernet (FCoE) allows the virtual host to send storage traffic over the server Ethernet uplinks if the FC connection.

  B. Virtual Ethernet Port Aggregator (VEPA) combines redundant server talks into a single high-bandwidth trunk.

  C. Intelligent Resilient Framework (IRF) allows redundant server links to connect to different physical switches.

  D. Net Stream and sFlow technologies provide the built-in capability to optimize bandwidth flows dynamically.

  Correct Answer: C

• Question 52:

  Which task does the HP Software-Defined Networking (SDN) Developer Support Description service help a customer perform?

  A. Replace existing virtual switches with HP-supported software-based switches.

  B. Create, test, and troubleshoot SDN applications

  C. Determine whether the company's network infrastructure is ready for SDN.

  D. Develop a migration plan to an SDN environment.

  Correct Answer: A

• Question 53:

  

  Which exhibit shows the better Open Shortest Path First (OSPF) area scheme and for which reason?

  A. Exhibit 1 because it allows the application of access control lists (ACLs) between users and the data center

  B. Exhibit 1 because the campus and data are separate areas

  C. Exhibit 2 because every area has similar numbers of routers

  D. Exhibit 1 because every area has fewer than 50 routers

  E. Exhibit 2 because every area has fewer than 35 routers

  Correct Answer: B

• Question 54:

  Network architect is recommending that a customer move from a three-tier campus LAN topology to a two-tier topology that routes traffic distribution layer provides firewall services and STP root guard. As a best practice, where should firewall servicesand STP root guard beimportant topology?

  A. These security features should be implemented at both the network access layer and the core.

  B. These security features should be implemented at the core.

  C. These security features should be implemented at the network access layer.

  D. Firewall services features should be implemented at the core, and STP root guard be implemented at the access layer

  Correct Answer: C

• Question 55:

  An architect is planning an HP Wired-WLAN solution for an office with approximately 4000 users who will use the wireless network rather heavily and who need to roam seamlessly. The solution will have 256 MSM 460 APs. What is one reason for using two HP Wired- WLAN controllers for this solution?

  A. Each Wired-WLAN controller can only support 2000 users.

  B. The customer needs fast roaming, which requires a mobility solution between two controllers.

  C. Forwarding traffic trough two controllers can prevent a bottleneck due to heavy usage.

  D. Each Wired-WLAN controller can only support 128APs.

  Correct Answer: C

• Question 56:

  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

  Correct Answer: B

• Question 57:

  Data center includes services within the same VLAN and subnet that communicate with each other multicast application. Variable Internet Group Management Protocol (IGMP) on this VLAN on data center switches?

  A. To enforce security boundaries between servers assigned to different multicast groups

  B. To eliminate multicast traffic on server ports that have not requested the multicasts

  C. To ensure that different applications do not use overlapping multicasts addresses

  D. To enable the servers to hear each other's multicast transmission

  Correct Answer: B

• Question 58:

  A network architect is explaining the differences between deploying two switches in an HP Intelligent Resiliency Framework (IRF) virtual switch and deploying two switches that implement standard Virtual Routing Redundancy Protocol (VRRP). Which statement correctly describes an advantage of IRF?

  A. IRF failover occurs in 3 to 4 seconds, whereas VRPF failover occurs in 10 or more seconds

  B. Unlike VRRP, which requires as least two addresses to be listed. Dynamic Host Configuration Protocol (DHCP) scopes list a single IP address for the default gateway

  C. The IRF virtual switch runs a separate routing in each member, which enhances the redundancy and reliability of the overall solution

  D. Multiple IRF members can actively route traffic for the same subnet and use the same IP address and routing control plane

  Correct Answer: D

• Question 59:

  A customer has a policy of using open standard protocols to maintain the flexibility to use multiple vendors. Which protocols are open standard (three.)

  A. PVST+

  B. MSTP

  C. CDP

  D. OSPF

  E. IGRP

  F. LLDP

  Correct Answer: BDF

• Question 60:

  A network architect is designing a solution with HP products. A customer has the following requirements for controlling the management access for administrators:

  Administrators are assigned privileges when they log in based on their identity Security policies related to password complexity and password rotation, like the company's Windows domain policies, are enforced for administrator credentials The company can easily revoke the access of administrator how have the company method Administrator have a backdoor into the management interface in case network connectivity fails in any way

  Which option meets the company's requirements?

  A. Authentication to a RADIUS server with local authentication as a secondary method

  B. Authentication with a password that meets the complexity requirements and is stored locally on each device

  C. Authentication to local user accounts with TACACS+ authenticates as a secondary method

  D. Authentication to a TACACS+ server

  Correct Answer: A
