QUESTION 11
A customer has implemented an HP 3PAR StoreServ 7200 and needs to non-disruptively change the RAID characteristic of a virtual volume. The customer must also change the disk tier where the virtual volume resides. Which HP 3PAR command or software feature should the customer use to accomplish this task?

A. tunevv
B. Adaptive Optimization
C. Dynamic Optimization
D. tunesys

Answer: A
Explanation:
tunevv - Change the layout of a virtual volume.
SYNTAX
The tunevv command uses one of the following syntax conventions:
tunevv usr_cpg <cpg> [options] <VV_name>
tunevv snp_cpg <cpg> [options] <VV_name>
tunevv restart [options] <VV_name>
tunevv rollback [options] <VV_name>
SUBCOMMANDS
usr_cpg <cpg>
Moves the logical disks being used for user space to the specified CPG.
snp_cpg <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.

QUESTION 12
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

Answer: C
Explanation:
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.

Which change to their environment is recommended?

A. upgrade to larger disks in the storage array
B. install additional disks in the storage array
C. set up replication between the storage blades and the storage array
D. install additional SAN switches

Answer: B

QUESTION 14
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

Answer: D
Explanation:
Note:
* To prevent losing access to data during any maintenance operation on components of the SAS fabric, including the SAS switches, SAS cables, and I/O modules on the disk enclosure, first power down the storage blades using the procedures to shut down the management group in the HP StoreVirtual Storage Online Help or the HP StoreVirtual Storage User Guide.

QUESTION 15
A customer uses HP 3PAK System Reporter and Adaptive Optimization with an HP 3PAR StoreServ 10000 Storage System that runs HP 3PAR OS 3.1.1. The customer is planning to upgrade the storage system to HP 3PAR OS 3.1.2. The customer needs to use System Reporter and Adaptive Optimization on the storage system after the upgrade.
Which complications will the customer encounter after performing the upgrade? (Select two)

A. System Reporter backups must be reconfigured
B. System Reporter data does not migrate
C. Adaptive Optimization is disabled
D. System Reporter databases become corrupt
E. Adaptive Optimization must be reconfigured.

Answer: BC
Explanation:
B: Recreation of the AO configuration on the nodes is a manual process. There is no automated means of transferring AO configurations from System Reporter onto the HP 3PAR OS 3.1.2 system.
C: AO behavior continues unchanged for HP 3PAR OS 3.1.1 and earlier. For HP 3PAR OS 3.1.2 systems, Adaptive Optimization behaves as follows:
* AO configurations for HP 3PAR OS systems are allowed insofar as they are not deleted following an upgrade from HP 3PAR OS 3.1.1. However, these AO configurations are not executed by regionmover and are marked as inactive.
* Following an upgrade from HP 3PAR OS 3.1.1, AO configurations remain and can be used by administrators as a reference to recreate the AO configurations on the nodes.

QUESTION 18
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

Answer: B
Explanation:
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 20
A customer needs to be able to recover their data in the event of a site failure. They have a strict recovery point objective for their business-critical applications.
Which technique should the customer use?

A. snapshots
B. backups to tape
C. backups to disk
D. remote replication

Answer: D
Explanation:
Need replication to get the data to a backup site.
Note:
* Recovery Point Objective (RPO) refers to the required point-in-time to which a DR solution can restore the state of data for a particular service, for example, how much data loss is acceptable following a disaster. These requirements can range from "close to zero" data loss (for high-value financial transactions, for example) to some small number of minutes of the most recent data, to loss of the past 1-2 days of data, depending on the criticality of the data to the enterprise.
