  -

  HP ProLiant BL460c Server Blades running VMware vSphere and Windows 2008 on physical server systems

  -

  HP StoreVirtual 4430

  -Cisco Nexus 5000 switches

  The HP Virtual Connect Flex-10 modules connect to the switches in three 10Gb shared uplink sets. The storage connects to the switches via 10Gb. During a design meeting for the new environment the customer asks for the method with the least amount of downtime to migrate the data for their physical servers to the new storage arrays.

  Which method should you suggest?

  A. HP Peer Motion

  B. HP Remote Copy

  C. HP MPX200

  D. VMware VMotion

  Correct Answer: B

• Question 45:

  An existing environment contains a two-node HP 3PAR StoreServ 10400 storage array with approximately 60 TB of capacity spread across three tiers. The customer plans to replicate their business critical data to a remote DR site. The customer cannot afford to lose any of this data. You propose that the customer install an HP 3PAR StoreServ 7400 Storage system at the DR site.

  The CFO does not want the remote equipment to sit idle, so the customer will use that equipment for data mining. The results must be replicated back to the main site. The customer also requires that the replication of the data mining results have zero impact on the data mining performance.

  Which HP 3PAR technology enables the proposed solution to meet the customer requirements?

  A. Peer Motion

  B. Mixed Mode Replication

  C. Online Import

  D. Adaptive Optimization

  Correct Answer: B

• Question 46:

  You are sizing a solution based on performance requirements.

  How do you calculate the number of front-end I/ Os versus back-end I/O when doing single writes? (Select three.)

  A. On RAID 1, a single front-end I/0 results in 1 back-end I/O

  B. On RAID 5, a single front-end I/O results in 4 back-end I/Os

  C. On RAID 5, a singe front-end I/0 results in 3 back-end I/Os

  D. On RAID 6, a single front-end I/O results in 4 back-end I/Os

  E. On RAID 6, a single front-end I/O results in 6 back-end l/Os

  F. On RAID 1, a single front-end I/O results in 2 back-end I/Os

  Correct Answer: BEF

• Question 47:

  You are working with a customer to design and install a Fibre Channel storage solution based on HP 3PAR StoreServ Storage.

  The customer wants data migration to be part of the solution. The IT environment includes VMware vSphere 5 and Windows 2008 R2 servers.

  The customer intends to utilize the existing non-HP array for Tier 2 storage on the Windows 2008 R2 servers.

  The existing array is also being used as the target of the customer backups. and that data will not be migrated.

  The customer wants to capitalize on their previous purchases and spend as little as possible for data migration. What should you recommend the customer use to migrate the data? (Select two)

  A. HP 3PAR Remote Copy

  B. HP MPX200 Multifunction Router

  C. HP 3PAR Online Import

  D. HP 1606 Extension SAN Switch

  E. VMware Storage \/Motion

  Correct Answer: BE

• Question 48:

  You are reviewing a colleague's design for a new storage environment. The solution consists of two HP 3PAR StoreServ arrays. The colleague also proposes an HP Multi-protocol Router Blade for the B-Series to extend the fabric.

• Question 50:

  A leading automotive technology company wants to increase the performance and capacity of the storage infrastructure that supports the design and manufacture of its line of Formula 1 racing cars. The company is also interested in safeguarding its mission-critical data and eliminating the threat of business disruption. Due to the massive engineering and technical effort required to create a new race car design and to enable regular delivery of upgraded parts to the race track while maintaining a competitive edge, it is necessary to have advanced applications running on a high-performance IT infrastructure. The company operates out of two data centers. The centers support a Plant Lifecycle Management database, an Enterprise Resource Planning (ERP) system, and various trackside systems to set up the race car and aid race strategy. In addition, the centers run applications for Computer-Aided Design (CAD) Computer-Aided Manufacturing (CAM), and Computational Fluid Dynamics (CFD) packages. The company has deployed Oracle and SQL databases, VMware virtual machines, email, and all other applications on an HP 6400 Enterprise virtual Array (EVA). The EVAs automatically replicate between the two data centers to guard against failure. The EVAs are aging, applications are more sophisticated, data volumes have grown exponentially, and bottlenecks in the storage system are now having a significant effect on the performance of the simulation and analysis tools that are vital to the company's competitive position. The data storage problem has reached a point where the company is forced to store primary data at the secondary site causing the loss of their disaster recovery capability. The company's top five IT Improvement goa's are:

  -Reduce complaints about storage system availability.

  -increase support for sophisticated design and manufacturing applications.

  -Provide a robust replication capability between data centers.

  -increase storage utilization while deploying additional capacity.

  -Simplify operations during peak workloads.

  Moreover, the company's top three business benefit goals are:

  -Ensure rapid data retrieval to aid in quick decision making.

  -Protect mission-critical data and ensure business continuity.

  -Recover costs from existing infrastructure, thus providing increased IT funds for additional projects.

  You are proposing an HP StoreOnce Backup System solution.

  Which tuning should be planned to performance and meet the customer business goals?

  A. Set up appendable pools.

  B. Configure multistreaming.

  C. .Enable multiplexing

  D. Disable housekeeping.

  Correct Answer: B
