  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.

• Question 22:

  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
  A. tunevv

  ---

  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.

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

  ---

  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.

• Question 27:

  A storage administrator plans to migrate data from an HP EVA4400 to an HP 3PAR StoreServ 7000 Storage System. The administrator needs to ensure that after the upgrade, in the event of a failure, hosts can access data replicated to another HP 3PAR without disruption.

  Which licensed option of the HP 3PAR StoreServ 7000 Storage System provides this capability?

  A. SmartStart
  B. Peer Persistence
  C. Virtual Service Processor (VSP)
  D. N_Port ID Virtualization (NPIV)
  B. Peer Persistence

  ---

  HP 3PAR Peer Persistence Software allows you to break the boundaries of storage, enabling your hosts, and data to move freely across data centers without impacting your business applications. It helps you in implementing a true cloud solution, where storage resources are shared across data centers, and are not constrained by their physical boundaries. Peer Persistence enables 3PAR systems located at metropolitan distances to act as peers to each other, presenting a nearly continuous storage system to hosts and servers connected to them.

  This capability allows customers to configure a high-availability solution between two sites or data centers where switchover and switchback remains transparent to the hosts and applications running on those hosts. This secures business continuity without impacting performance and enables load balancing putting investments at both the data centers to optimal use.

  Incorrect: Not A:

  *

  SmartStart assisted with Windows OS installation process and integrated and optimized HP ProLiant server support software drivers, utilities and management agents, known as ProLiant Support Packs (PSPs).

  *

  SmartStart was a single-server deployment tool that simplified HP ProLiant G7 server (and earlier) setup, providing a repeatable way to deploy consistent configurations. It was included in the HP Insight Foundation suite for ProLiant. Insight Foundation suite and SmartStart products are end-of-life (EOL) and the last servers they ship with are ProLiant G7 servers. ProLiant Gen8 servers and beyond use Intelligent Provisioning which is initiated by pressing during the server boot (POST) process.

  Not C: HP 3PAR Service Processor functions as the communication interface between the customer's IP network and HP 3PAR Central by managing all service-related communications in both directions.

  Not D: N_Port ID Virtualisation (NPIV) is an industry-standard Fibre Channel (FC) protocol that provides a means to assign multiple FC addresses on the same physical link.

• Question 28:

  A customer needs to migrate data to a new database environment. They need to make a physical copy of their data that can be presented to the new environment with the highest level of availability. Which form of replication should the customer use?

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

  ---

  Incorrect: Not B: A storage snapshot is a set of reference markers, or pointers, to data stored on a disk drive, on a tape, or in a storage area network (SAN). A snapshot is something like a detailed table of contents, but it is treated by the computer as a complete data backup. Snapshots streamline access to stored data and can speed up the process of data recovery. There are two main types of storage snapshot, called the copy-on-write (or low-capacity) snapshot and the split-mirror snapshot. Utilities are available that can automatically generate either type.

• Question 29:

  A customer with multiple HP 3PAR P10000 Storage Systems needs to move data between the arrays. They need to ensure that the migration will not disrupt their applications, users, or services. Which storage method should the customer use to achieve this goal?

  A. point-in-time copies
  B. backups to disk
  C. storage federation
  D. deduplication
  C. storage federation

  ---

  Storage federation from HP enables the online non-disruptive movement of storage volumes between arrays in a metro area. Unlike external storage virtualization appliances that add cost, complexity and downtime, storage federation from HP creates a persistent pool of capacity using native communication between system controllers.

• Question 30:

  What is a main benefit of HP StoreOnce deduplication?

  A. It enables snapshots of deduplicated date to be made easily.
  B. It encrypts data to prevent corruption during the backup cycle.
  C. It optimizes storage capacity to retain more data within a disk backup device.
  D. It allows the devices that contain the data to be thinly provisioned.
  C. It optimizes storage capacity to retain more data within a disk backup device.

  ---

  Note: Data deduplication is a specialized data compression technique for eliminating duplicate copies of repeating data.
