HP HP0-J66 Online Practice Questions and Exam Preparation

HP HP0-J66 Online Questions & Answers

• Question 51:

  A storage administrator needs to perform a gradual migration of large backup volumes and jobs to a remote D2D system over time. Because this data is being replicated for the first time, the administrator needs to populate the target device with all the relevant hash codes.

  Which method should the administrator use to achieve this goal?

  A. using co-location
  B. using removable media
  C. seeding data over the WAN link
  D. setting initializer to migration
  C. seeding data over the WAN link

  ---

  *

  prior to being able to replicate only unique data between source and target D2D, we must first ensure that each site has the same hash codes or "bulk data" loaded on it ?this can be thought of as the reference data against which future

  backups are compared to see if the hash codes exist already on either source or target. The process of getting the same bulk data or reference data loaded on the D2D source and D2D target is known as "seeding".

  *

  Seeding is generally is a one-time operation which must take place before steady-state, low bandwidth replication can commence. Seeding can take place in a number of ways:

  / Over the WAN link ?although this can take some time for large volumes of data / Using co-location where two devices are physically in the same location and can use a GbE replication link for seeding. After seeding is complete, one unit is

  physically shipped to its permanent destination.

  / Using a form of removable media (physical tape or portable USB disks) to "ship data" between sites.

• Question 52:

  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
  B. Four

  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 53:

  A customer is planning to migrate from an HP EVA to an HP 3PAR StoreServ 7000 Storage System The customer uses disk groups on the EVA for fine-grained database management.

  What can the customer use to achieve fine-grained database management on the HP 3PAR StoreServ 7000?

  A. logical volumes
  B. common provisioning groups
  C. disk groups
  D. virtual volumes
  B. common provisioning groups

• Question 54:

  A customer provides their requirements for a storage solution.

  A consultant, using his experience and product knowledge, has designed a solution.

  He needs to verify that the storage design and licensing rules have been adhered to, and that the solution can be supported by HP. Which resource can provide this information?

  A. HP StorageWorks Sizing Tool
  B. HP ActiveAnswers
  C. HP Storage Solutions Design Guide
  D. HP SAN Design Validator
  A. HP StorageWorks Sizing Tool

  ---

  It is recommended that the HP StorageWorks Sizing Tool (http://www.hp.com/go/storageworks/sizer) is used to identify the product and WAN link requirements because the required bandwidth is complex.

• Question 55:

  A customer plans to migrate data from an HP EVA8400 Storage System to two HP 3PAR StoreServ 7400 Storage Systems. The new storage systems must be configured to support connection redundancy. How many Service Processors must the customer deploy to support the solution?

  A. One
  B. Two
  C. Three
  D. Four
  A. One

• Question 56:

  A customer plans to migrate data from a third-party storage system to an HP 3PAR StoreServ 7000. They have an ISP connection between two offices. The new storage system must replicate data between the offices. What should the customer implement?

  A. IP-based Remote Copy with Synchronous Replication
  B. FC-based Remote Copy with Synchronous Replication
  C. FC-based Remote Copy with Asynchronous Replication
  D. IP-based Remote Copy with Asynchronous Replication
  D. IP-based Remote Copy with Asynchronous Replication

• Question 57:

  A customer is planning to implement an HP StoreVirtual 4330FC Storage System

  Which type of cable do they need to connect the storage system to the fabric?

  A. SC Fibre Channel
  B. LC Fibre Channel
  C. iSCSI
  D. SAS
  A. SC Fibre Channel

• Question 58:

  A company has a first-generation deduplication appliance and is considering adding an HP StoreOnce 6200 Backup System to its environment. Which benefits can this company realize by deploying an HP StoreOnce 6200 Backup System? (Select two.)

  A. can scale up to 784 TB of usable storage
  B. federated non-disruptive data mobility between third-party systems
  C. deduplicates data anywhere without the need for rehydration
  D. performance throughput of 200 TB/hour
  E. automatic failover on couplet failure
  C. deduplicates data anywhere without the need for rehydration
  E. automatic failover on couplet failure

  The HP B6200 StoreOnce Backup System provides:

  *

  Deduplication to drive more efficient storage of data

  *

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

  *

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