HP0-J66 Online Practice Questions and Answers

Correct Answer: C

Correct Answer: B

The HP 3PAR Adaptive Optimization (AO) software takes optimization a step further into sub-LUN tiering. AO migrates sub-LUN data across CPGs based on user-defined policies. Two or three CPG tiers can be specified per policy; all

volumes inside a CPG are subject of an AO policy. AO policies usually operate on an FC and NL tier or on an SSD, FC, and NL tier.

This tool can improve system response and reduce disk acquisition cost by storing frequently accessed data in the faster tier while moving infrequently accessed data to the slower and cheaper slower tier.

Incorrect:

Not D: Related to online migration:

P 3PAR's Dynamic Optimization (DO) software offers the functionality of EVA's Dynamic LUN Migration: volumes are migrated online to another CPG with a different RAID level, set size, drive media type , etc.

Correct Answer: B

SAN Visibility is a complementary software utility for HP customers that helps with SAN Analysis, SAN Diagnostics and SAN Optimization. SAN Visibility saves you considerable time, money, and effort by automating inventory activities and

providing a quick and accurate view of your SAN topology. SAN Visibility has an automated report generation feature that produces recommendations, topology diagrams, and informative SAN element reports for switches, host bus adapters

and storage array connectivity. SAN Visibility runs on any Windows desktop or laptop which has network connectivity to a switch within your SAN.

Not A: HP's storage security self-assessment tool helps you gauge your storage privacy vulnerabilities online and free of charge--and gain valuable insight on how to better manage risk, protect sensitive data and comply with data privacy

regulations.

Correct Answer: D

Challenges in Enterprise Data Protection Requirements for a modern Enterprise Data Protection solution have many drivers:

*

Exponential growth of data Shrinking backup windows

*

The need to design, plan and integrate a comprehensive Disaster Recovery capability

*

The need for backup devices to be more available than ever before

The HP B6200 StoreOnce Backup System responds to all these requirements by providing:

*

Deduplication to drive more efficient storage of data

*

Large device scalability to ensure every backup has access to devices and, so, reduce queuing time

*

(D) In-built low bandwidth replication for cost-effective copies of data offsite as part of a Disaster Recovery plan

*

HP Autonomic failover (with appropriate ISV software) to allow backups to continue, even if a node in an HP B6200 StoreOnce Backup System fails.

*

High scalability in terms of capacity, performance and replication to ensure the system grows as your business grows.

Correct Answer: D

Do not send multiplexed data to StoreOnce B6200/D2D Backup Systems. "Multiplexing" data streams from different sources into a single stream in order to get higher throughput used to be a common best practice when using physical tape drives. This was a necessity in order to make the physical tape drive run in streaming mode, especially if the individual hosts could not supply data fast enough. But multiplexing is not required and is in fact a BAD practice when it comes to D2D or B6200 deduplication devices.

Note:

* Users familiar with the HP VLS System should be aware that the HP StoreOnce B6200 Backup System does not behave in the same way and needs a completely different approach when architecting and tuning for best performance. Do not assume that an HP B6200 Backup System can replace an HP VLS System without major re-evaluation of requirements and alignment with HP B200 best practices.

Correct Answer: B

Correct Answer: B

Note:

*

In RAID 10, often referred to as RAID 1+0 (mirroring and striping), data is written in stripes across primary disks that have been mirrored to the secondary disks.

*

RAID 10: Mirroring without parity, and block-level striping

*

RAID 1+0: (a.k.a. RAID 10) mirrored sets in a striped set (minimum four drives; even number of drives) provides fault tolerance and improved performance but increases complexity.

*

By its definition, a Network RAID 10 volume consumes capacity at twice the rate of a Network RAID 0 volume.

Correct Answer: C

Correct Answer: C

Setting Up a Windows Hyper-V Server/HP 3PAR StoreServ Storage Configuration Required is a Windows server with an x64-based processor running an x64 version of Windows Server 2012, Windows Server 2008 Standard, Windows Server 2008 Datacenter, Windows Server 2008 Enterprise (SP1, SP2), or Windows Server 2008 R2 Server.

Incorrect: Not A, not B, not D: No particular parameters need to be set in the Hyper-V software to work with the HP 3PAR StoreServ Storage; no additional steps are necessary on the HP 3PAR StoreServ Storage to work with a Windows Hyper-V server
