HP HP0-J66 Exam Questions & Answers

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.

Correct Answer: A

tunevv - Change the layout of a virtual volume.

SYNTAX

The tunevv command uses one of the following syntax conventions:

tunevv usr_cpg [options]

tunevv snp_cpg [options]

tunevv restart [options]

tunevv rollback [options]

SUBCOMMANDS

usr_cpg

Moves the logical disks being used for user space to the specified CPG.

snp_cpg

Moves the logical disks being used for snapshot space to the specified CPG.

restart

Restarts a tunevv command call that was previously interrupted because of component failure, or because of user initiated cancellation. This cannot be used on thinly provisioned virtual volumes.

rollback

Returns to a previously issued tunevv operation call that was interrupted. The canceltask command needs to run before the rollback.

This cannot be used on thinly provisioned virtual volumes.

DESCRIPTION

The tunevv command is used to change the properties of a virtual volume that was created with either the createvv or createtpvv command by associating it with a different CPG.

Incorrect:

Not B: The HP 3PAR Data Optimization Software Suite v2 combines capabilities that provide autonomic storage tiering and dynamic data mobility with assured quality of service . Adaptive Optimization provides highly reliable, non-disruptive,

cost-optimized storage tiering at the sub-volume level to deliver the right QoS to the right data at the right time on a large scale and Dynamic Optimization delivers it at the volume level.

Not D:

Best practice is to run Autonomic Rebalance (also known as tunesys) after adding drives.
