HP0-J66 Online Practice Questions and Answers

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.

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.

HP Virtual Connect FlexFabric interconnects pair with HP FlexFabric 10Gb 2-port onboard or mezzanine based adapters and provide FlexNIC functionality with Converged Network Adapters (CNAs) capable of either iSCSI, FCoE or native Fibre Channel storage protocols. With Virtual Connect 4.00, this flexible bandwidth capability is extended further with minimum and maximum bandwidth settings configurable from within the Virtual Connect management interface. This allows you to prioritize certain types of traffic over other types if contention occurs as well as insuring that certain networks have guaranteed bandwidth.

Correct Answer: D

Correct Answer: C

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

Correct Answer: B

EVA to 3PAR Online Import manages the migration of data from a source EVA storage system to a destination 3PAR storage system. Using EVA to 3PAR Online Import, you can migrate EVA virtual disks and host configuration information to a 3PAR destination storage system without changing host configurations or interrupting data access.

Correct Answer: DE

Note:

* Adaptive load balancing (ALB)

Uses interfaces simultaneously for data transfer (receive and transmit load balancing). If one connection fails, the remaining connection continues without disruption to the storage nodes operation or iSCSI sessions. It offers the benefits of the

increased transmission rates without additional switch configuration. Interfaces in an ALB bond may be connected to different switches and therefore supports switch failover.
