HP HP ExpertONE Certification HP0-J67 Questions & Answers

• Question 81:

  At a customer meeting with the CEO and CFO, you present a storage solution consisting of several HP 3PAR StoreServ 7400 systems for their long-term storage strategy. While elaborating on the storage system performance directly related to the number of disks and linear scalability in your proposed solution, you realize that the attention of your audience has started to decline.

  What has gone wrong?

  A. This is not the correct audience for storage system performance scalability.

  B. These CxOs would have liked you to inform them about improved infrastructure requirements.

  C. The CxOs of the customer are more interested in future firmware features.

  D. Rather than stating the obvious, you should have focused more on disk technology.

  Correct Answer: A

• Question 82:

  You are designing an HP 3PAR StoreServ solution that replicates to a second HP 3PAR StoreServ array at the customer secondary data center, which is 20 miles away. You determine that the round trip latency between sites is 5ms. Which replication solution should you recommend?

  A. Asynchronous Real Time

  B. Synchronous Long Distance

  C. Synchronous

  D. Asynchronous Periodic

  Correct Answer: D

• Question 83:

  Your customer wants to replicate backup data from branch offices to a primary data center where an HP StoreOnce 4430 Backup System using HP StoreOnce Catalyst is located. The backup application is HP Data Protector 7.01. The file and application servers have Windows 2003, Windows 2008 and SUSE Linux 9 and 10 installed. As a long-term strategy, the customer wants to migrate all services to the primary data center. No additional hardware can be purchased for the branch offices, and complexity should be minimized.

  In addition to the HP EBS Compatibility Matrix, which additional HP resources should be used to validate interoperability of a new solution?

  A. HP Enterprise Backup Solution Design Guide

  B. HP Data Protector Platform and Integration Matrix

  C. HP Data Protector Concepts Guide

  D. HP SAN Design Reference Guide

  Correct Answer: AB

• Question 84:

  You are designing an HP SPAR StoreServ solution to host a customer Microsoft Hyper-V 2012 environment load on the transport network?

  A. T10 Unmap (T10U)

  B. Offload Data Transfer (ODX)

  C. vStorage APIs for Array Integration (VAAI)

  D. T10 Data Integrity Field (DIF)

  Correct Answer: B

• Question 85:

  You are asked to review the design of an HP 3PAR StoreServ implementation due to complaints from the customer regarding performance of virtual volumes on their production disk array. You make the following notes regarding the customer environment: Primary Data Center (DC) -> Secondary DC = 30 miles and 5ms roundtrip latency; Synchronous Replication Primary DC -> Disaster Recovery DC = 200 miles and 15ms roundtrip latency; Periodic Asynchronous Replication

  How should you resolve their performance problem?

  A. Convert all replication jobs to Synchronous Long Distance.

  B. Convert the replication job from the primary DC to the DR DC to Synchronous Long Distance.

  C. Convert the replication job from the primary DC to the; Secondary DC to Synchronous Long Distance.

  D. Convert all replication jobs to Periodic Asynchronous.

  Correct Answer: D

• Question 86:

  Refer to the exhibit.

  

  A customer complains about poor application performance on their existing two-node HP P4500 Virtualization SAN and provides you the chart in the exhibit. Which conclusion can you draw from this graph?

  A. Queue depth of the cluster exceeds the recommended limit, and total disk l/O should be checked.

  B. Queue depth of the storage environment is acceptable, and performance issues should be checked on the application level.

  C. Queue depth of the storage cluster is in the optimal range, and throughput should be checked.

  D. Queue depth is acceptable, and total latency peaks are too high during business hours.

  Correct Answer: B

• Question 87:

  Your customer needs a solution to provide non-disruptive data streaming across two sites. The customer is not limited to an existing transport protocol in their environment but wants to use deduplication for their office data.

  Which HP storage solution should you recommend?

  A. HP StoreEasy

  B. HP 3PAR StoreServ

  C. HP EVA

  D. HP StoreOnce

  Correct Answer: B

• Question 88:

  You are proposing an HP 3PAR StoreServ Storage solution to a customer who regularly misses exporting new virtual volumes to all hosts that need access to the LUN.

  Which feature of an HP 3PAR StoreServ Storage system solves this problem?

  A. Autonomic Rebalance

  B. Persistent Ports

  C. Autonomic groups

  D. Common Provisioning groups

  Correct Answer: C

• Question 89:

  Your customer is migrating to VMware vSphere 5. Your solution includes HP 3PAR StoreServ Storage with licenses for Remote Copy and Adaptive Optimization. The customer is interested in implementing VMware Storage DRS and asks if there are any interoperability concerns with your solution.

  What should you recommend to ensure that VMware Storage DRS coexists with your solution?

  A. VMware Storage DRS should be configured for capacity-based decisions

  B. HP 3PAR Security Software Suite must be added to the solution

  C. HP 3PAR Remote Copy must be configured for synchronous replication.

  D. VMware Storage DRS should be set up in manual mode with I/O metric enabled.

  Correct Answer: D

  VMware Storage DRS provides both initial and ongoing placement recommendations of virtual machine and virtual disk drives based on capacity and I/O workloads. http://www.vmware.com/files/pdf/techpaper/vsphere-storage-drsinteroperability.pdf Best practice:

  Do not mix Adaptive Optimization with any other application or process that moves data on a LUN or between LUNs. Any applications or processes that move data on a LUN or between LUNs, such as VMware Storage DRS, should be

  disabled, as they might conflict with each other. Only Adaptive Optimization, being the lowest level (storage level), should be used.

• Question 90:

  You have designed a new SAN fabric for a customer. The fabric consists of Cisco MDS 8/24c Fabric Switches for HP BladeSystem c-Class. Which mode allows automatic mapping of physical WWNs to virtual WWNs using NAT?

  A. Access Gateway

  B. FlexFabric

  C. NPV

  D. Virtual Domains

  Correct Answer: C
