HP HP0-J66 Online Questions & Answers

• Question 11:

  A customer using high-speed parallel operations needs to encrypt data in 128-bit blocks with a key size of up to 256 bits. Which security standard should the customer use?

  A. RC5
  B. DES
  C. AES
  D. SHA
  C. AES

  ---

  The key size used for an AES cipher specifies the number of repetitions of transformation rounds that convert the input, called the plaintext, into the final output, called the ciphertext. The number of cycles of repetition are as follows:

  Incorrect:

  Not A: RC5 has a variable block size (32, 64 or 128 bits), key size. Not B: DES is now considered to be insecure for many applications. This is chiefly due to the 56- bit key size being too small.

• Question 12:

  A customer plans to implement an HP B6200 Backup System.

  Which benefit does mapping data types to different backup devices provide?

  A. decreased installation cost
  B. decreased recovery time
  C. increased deduplication ratio
  D. increased media utilization
  C. increased deduplication ratio

  ---

  Mapping the same data type to the same device improves deduplication ratios, even if it comes from multiple media servers. Reference; HP B6200 Backup System, Recommended Configuration Guidelines

• Question 13:

  For how many days after installation is an Online Import license valid?

  A. 30
  B. 60
  C. 180
  D. 365
  C. 180

  ---

  There is a 180 day time based Peer motion shipped free, this license time starts at installation time, so if the license is enabled at the factory then it will start to tick down.

  The license will generate appropriate alerts once the 180 days is drawing close.

  Alternatively there is a permanent license too!

• Question 14:

  A customer needs to be able to perform an instant recovery of database data files. The recovery point is one hour to enable them to have a specified point time to restore the data if the data migration fails. Which form of data replication enables the customer to achieve this goal?

  A. volume clones
  B. backups to disk
  C. asynchronous replication
  D. snapshots
  B. backups to disk

  Incorrect: Not A, not D: HP 3PAR StoreServ 7200 Number of disk drives: 8-144 drives

• Question 16:

  A customer is looking for a new storage system that provides storage management security for their Windows-based environment. They are considering an HP StoreVirtual 4000.

  Which security function does this solution provide?

  A. Active Directory support
  B. Centralized Management Console (CMC) authentication
  C. proxy server exclusion
  D. quorum alarms
  A. Active Directory support

  ---

  Note:

  * Now available ?LeftHand OS version 10 software (formerly SAN/iQ) ?"one click" online upgrades, support for Windows 2012, Active Directory integration, proxy server support and quorum alerts.

• Question 17:

  A customer requests a storage and server environment assessment prior to the installation of additional SAN components. Which HP software utility provides a quick and accurate view of the customers SAN topology?

  A. Storage Security Self-Assessment Tool
  B. SAN Visibility
  C. Storage Product Selector
  D. SAN Designer
  B. SAN Visibility

  ---

  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.

  Incorrect:

  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.

• Question 18:

  A company needs to migrate from their existing legacy storage system to a new multi-site cluster with Fibre Channel support and 10GbE ports. Which HP solution meets these requirements?

  A. HP StoreAII 9300 IB
  B. HP EVA P6500 FC/iSCSI
  C. HP StoreSure 2000
  D. HP StoreVirtual 4330 FC
  D. HP StoreVirtual 4330 FC

  ---

  HP StoreVirtual 4330 FC Host interface

  *

  1 GbE iSCSI (4) Ports and

  *

  10 GbE iSCSI (2) Ports and

  *

  8 Gb Fibre Channel (2) Ports

• Question 19:

  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
  D. hash-based chunking

  ---

  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 20:

  A customer is migrating data to a storage array with 7 TB of storage capacity. They need 6 TB to be presented on this array for an existing database requirement.

  Which storage virtualization technology should this customer use to optimize the utilization of their available storage?

  A. block-level data compression
  B. primary storage deduplication
  C. virtual replication
  D. thin provisioning
  D. thin provisioning

  ---

  Thin provisioning promises higher capacity utilization rates and is a feature in most storage systems. But buyer beware--not all thin technologies are created equal. HP Converged Storage offers the most comprehensive and advanced set of thin technologies in the industry. With HP, your data center can be lean and efficient.

  With HP thin technologies, you can:

  *

  Start thin, so you can get the most from every dollar and disk. Easily utilize 80% or more of your purchased capacity with thin provisioning, which, unlike competitive offerings, does not require pre-planning or space reservations.

  *

  Cut storage capacity needs in half--guaranteed.1

  Changes IT refresh cycles by providing simple data mobility across clusters or generations of storage systems without downtime.

  *

  Expect high efficiency and high performance--not tradeoffs. With HP 3PAR StoreServ Storage, thin technologies are embedded in hardware, so you can run all of your workloads in a thin state and still have high performance.

  *

  Reclaim nearly 100% of unused space.

  HP's thin reclamation technology continually hunts down wasted space in fine-grained, 16k increments and returns that capacity to the system for use by other applications.
