• Question 42:

  A customer is planning to migrate data from an HP 3PAR F-200 to an HP 3PAR StoreServ 7000 Storage System. What should the customer use to migrate the data?

  A. Peer Motion

  B. Recovery Manager

  C. Online Import

  D. Remote Copy

  Correct Answer: A

  HP 3PAR Peer Motion Software is the first non-disruptive, do-it-yourself data migration tool for enterprise block storage. With Peer Motion, HP 3PAR Storage System customers can load balance I/O workloads across systems at will, perform technology refresh seamlessly, cost-optimize asset lifecycle management, and lower technology refresh capital expenditure.

  Unlike traditional block migration approaches, Peer Motion enables customers to migrate storage volumes between any HP 3PAR Storage Systems online, non-disruptively, and without complex planning or dependency on extra tools. Peer Motion leverages HP 3PAR Thin Built InTM technology to power the simple and rapid inline conversion of inefficient, "fat" volumes on source arrays to more efficient, higher-utilization "thin" volumes on the destination 3PAR Storage System.

  Peer Motion Manager is an add-on application that orchestrates all stages of the data migration lifecycle to ensure data migration is simple and fool-proof.

• Question 43:

  A customer needs to balance storage high availability and cost to meet various service level agreements, depending on the application requirement. Which storage methodology should the customer use?

  A. storage RAID

  B. storage federation

  C. storage tiering

  D. deduplicated storage

  Correct Answer: C

  Tiered storage is the assignment of different categories of data to different types of storage media in order to reduce total storage cost. Categories may be based on levels of protection needed, performance requirements, frequency of use,

  and other considerations. Since assigning data to particular media may be an ongoing and complex activity, some vendors provide software for automatically managing the process based on a company-defined policy.

  As an example of tiered storage, tier 1 data (such as mission-critical, recently accessed, or top secret files) might be stored on expensive and high-quality media such as double-parity RAIDs (redundant arrays of independent disks). Tier 2

  data (such as financial, seldom-used, or classified files) might be stored on less expensive media in conventional storage area networks (SANs). As the tier number increased, cheaper media could be used. Thus, tier 3 in a 3-tier system might

  contain event-driven, rarely used, or unclassified files on recordable compact discs (CD-Rs) or tapes.

  Incorrect:

  Not B:

  Much like vMotion in VMware environments, storage federation goes beyond the capabilities of storage virtualization. Storage federation from HP enables the online non-disruptive movement of storage volumes between arrays in a metro

  area. Unlike external storage virtualization appliances that add cost, complexity and downtime, storage federation from HP creates a persistent pool of capacity using native communication between system controllers.

• Question 44:

  A customer needs to be able to recover their data in the event of a site failure. They have a strict recovery point objective for their business-critical applications.

  Which technique should the customer use?

  A. snapshots

  B. backups to tape

  C. backups to disk

  D. remote replication

  Correct Answer: D

  Need replication to get the data to a backup site.

  Note:

  * Recovery Point Objective (RPO) refers to the required point-in-time to which a DR solution can restore the state of data for a particular service, for example, how much data loss is acceptable following a disaster. These requirements can range from "close to zero" data loss (for high-value financial transactions, for example) to some small number of minutes of the most recent data, to loss of the past 1-2 days of data, depending on the criticality of the data to the enterprise.

• Question 45:

  Which type of deduplication method is performed by HP StoreOnce D2D devices?

  A. object-level differencing

  B. pre-hash data encrypting

  C. metadata compressing

  D. hash-based chunking

  Correct Answer: D

  HP D2D (Disk to Disk) Backup Systems use Dynamic deduplication(hash-based chunking) technology that provides a significant price advantage over our competitors.

  Note:

  * HP offers two complementary deduplication technologies that meet very different customer needs:

  / Accelerated deduplication (object-level differencing) for the high-end enterprise customer who requires:

  Fastest possible backup performance

  Fastest restores

  Most scalable solution possible in terms of performance and capacity ?Multi-node low-bandwidth replication

  High deduplication ratios

  Wide range of replication models

  / Dynamic deduplication (hash-based chunking) for the mid size enterprise and remote office customers who require:

  Lower cost device through smaller RAM footprint and optimized disk usage

  A fully integrated deduplication appliance with lights-out operation

  Backup application and data type independence for maximum flexibility

  Wide range of replication models

• Question 46:

  A customer's network environment contains a third-party storage system and an HP BladeSystem with ProLiant server blades. The customer plans to migrate data to an HP StoreVirtual Storage System.

  The storage system must contain at least 20 TB of raw capacity.

  Which HP StoreVirtual Storage System should the customer deploy?

  A. HP StoreVirtual 4630

  B. HP StoreVirtual 4530

  C. HP StoreVirtual 4330

  D. HP StoreVirtual 4130

  Correct Answer: A

  4630 Capacity:

  Incorrect:

  Not B: 4530 Capacity:

  7.2TB Starting

  230.4TB Maximum

• Question 47:

  A customer plans to migrate data from a third-party storage system to an HP 3PAR StoreServ 7200 Storage System.

  The new storage system must provide up to 128 disk drives.

  How many additional drive chassis does the customer need?

  A. Three

  B. Four

  C. Five

  D. Six

  Correct Answer: B

• Question 48:

  A customer plans to migrate data from a third-party storage system to an HP StoreVirtual 4330FC Storage System. The new storage system must contain 7.2 TB of usable space after network RAID 10 and hardware RAID 10 are configured.

  How many nodes does the customer need?

  A. Three

  B. Four

  C. Six

  D. Eight

  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.

• Question 49:

  A customer uses HP 3PAK System Reporter and Adaptive Optimization with an HP 3PAR StoreServ 10000 Storage System that runs HP 3PAR OS 3.1.1. The customer is planning to upgrade the storage system to HP 3PAR OS 3.1.2. The customer needs to use System Reporter and Adaptive Optimization on the storage system after the upgrade.

  Which complications will the customer encounter after performing the upgrade? (Select two)

  A. System Reporter backups must be reconfigured

  B. System Reporter data does not migrate

  C. Adaptive Optimization is disabled

  D. System Reporter databases become corrupt

  E. Adaptive Optimization must be reconfigured.

  Correct Answer: BC

  B: Recreation of the AO configuration on the nodes is a manual process. There is no automated means of transferring AO configurations from System Reporter onto the HP 3PAR OS 3.1.2 system.

  C: AO behavior continues unchanged for HP 3PAR OS 3.1.1 and earlier. For HP 3PAR OS 3.1.2 systems, Adaptive Optimization behaves as follows:

  *

  AO configurations for HP 3PAR OS systems are allowed insofar as they are not deleted following an upgrade from HP 3PAR OS 3.1.1. However, these AO configurations are not executed by regionmover and are marked as inactive.

  *

  Following an upgrade from HP 3PAR OS 3.1.1, AO configurations remain and can be used by administrators as a reference to recreate the AO configurations on the nodes.
