HP HP ExpertONE Certification HP0-J66 Questions & Answers

• Question 71:

  A customer plans to migrate data from a third-party storage system to an HP 3PAR solution. The customer has leased data center space. Which HP 3PAR Storage solution must be integrated into an HP 3PAR rack?

  A. HP 3PAR StoreServ 10800

  B. HP 3PAR StoreServ 10400

  C. HP 3PAR StoreServ F200

  D. HP 3PAR StoreServ 7400

  Correct Answer: A

• Question 72:

  A customer is extending a SAN by using wavelength division multiplexing (WDM) to migrate their master database to a new data center. They need to ensure that there is adequate line speed to perform the migration in the event of a primary path failure.

  What should the customer do to achieve this goal?

  A. Ensure that all SAN devices use the same Fibre Channel speed.

  B. Ensure that all SAN switches have the same core PID number.

  C. Ensure that there are separate WDM paths for transmitting and receiving packets

  D. Ensure that a secondary path with sufficient buffer-to-buffer credits is available

  Correct Answer: D

  WDM devices extend the distance between two FICON directors. The devices are transparent to the directors and do not count as an additional hop. To accommodate WDM devices, you must have enough Fibre Channel BB_credits to maintain line-speed performance. WDM supports Fibre Channel speeds of 10 Gb/s, 8 Gb/s, 4 Gb/s, 2 Gb/s, and 1 Gb/s. When planning for SAN extension, BB_credits are an important consideration in WDM network configurations. Typical WDM implementations for storage replication include a primary and secondary path. You must have enough BB_credits to cover the distances for both the primary path and secondary path so that performance is not affected if the primary path fails.

• Question 73:

  A customer is planning to migrate a database to a new site. They need to create an extended SAN in a single fabric namespace by using a dedicated link over a distance of 200 km.

  Which network protocol should they use to achieve this goal?

  A. FCIP

  B. iFC

  C. FCoE

  D. iSCSI

  Correct Answer: A

  FCIP connects Fibre Channel fabrics over IP-based networks to form a unified SAN in a single

  fabric. FCIP relies on IP-based network services to provide connectivity between fabrics over LANs, MANs, or WANs.

  Note:

  HP SAN extension technologies include:

  *

  FCIP

  (greater than 10 km to 20,000 km)

  *

  FC-ATM

  *

  FC-SONET

  *

  WDM

  (greater than 35 km to 100?00 km)

  *

  Fibre Channel using long-wave transceivers

  (10 km?5 km)

• Question 74:

  A customer is preparing to migrate data between their data centers. They need to perform deduplicalion at the data creation point and eliminate the need for specialized deduplication hardware in their data centers. How does HP StoreOnce Catalyst enable the customer to achieve this goal?

  A. by performing source-side deduplication

  B. by performing switch-side deduplication

  C. by performing server-side deduplication

  D. by performing target-side deduplication

  Correct Answer: A

  By enabling source-side deduplication (Dedupe 2.0), HP has the advantage of performing deduplication at the data creation point. Source-side deduplication eliminates the need for specialist deduplication hardware at remote and branch office sites. StoreOnce Catalyst allows customers to align backup with data protection needs, such as minimizing bandwidth utilization when moving data between sites or data centers.
