HCE-3700 Online Practice Questions and Answers

Which three functions are performed by a VSP G1000 Virtual Storage Director (VSD)? (Choose three.)

A. It executes host I/O requests.

B. It calculates parity.

C. It manages cache segment usage.

D. It moves data to/from cache.

E. It executes software such as HDP or copy products.

A customer plans to migrate an interactive application from a VSP to VSP G1000. The application has consistent access across all its capacity with low hit rates and no particularly high I/O access areas. The application latency must be less or equal to 1.5 ms.

Which configuration do you recommend to satisfy the requirements?

A. an HDT pool consisting of SAS 10K and FMD drives

B. an HDP pool with FMD drives

C. an HDP pool consisting of NL-SAS and FMD drives

D. an HDP pool consisting of external LDEVs provisioned on a VSP F400 system

A customer has several Oracle databases with different workload profiles residing on old HUS systems. The customer wants to consolidate workloads on a new VSP G800 system to increase database performance and to reduce costs.

Which configuration would you use to accomplish this task?

A. Put all of the databases in a single HDT pool.

B. Put each database in its own HDT pool.

C. Put databases with the same workload profile together in their own HDT pool.

D. Put all database tablespaces and indexes in the first HDT pool, all redo logs in the second HDT pool, and all undo logs in a third HDT pool.

Your customer has an HDP pool dedicated to interactive production workloads. Which two applications are good candidates to share this HDP pool? (Choose two.)

A. customer relationship management

B. customer service call taking and dispatch

C. software development

D. backup repository

When testing an external LUN with default mapping on two paths, performance appears constrained and the utilization of the RAID group in the external storage system never exceeds 35% busy no matter how many test threads are generated. You want to increase the utilization of the external RAID group.

Which two actions will accomplish this task? (Choose two.)

A. Increase the external path LUN queue depth setting.

B. Increase the number of LUNs mapped from the external RAID group.

C. Change Cache Mode to "Disabled".

D. Increase the server HBA LUN queue depth to 64.

A user with a diskless VSP G800 uses ShadowImage from the G800 with a virtualized VSP G200 system. Application performance suffers during the frequent ShadowImage resynchronization operations.

What should be done to reduce the impact of the ShadowImage throughput in this scenario?

A. Configure both sets of disks into an HDT pool and let the HDT scheme manage the different workloads.

B. Define the ShadowImage target volumes to use dedicated external FC paths using dedicated RAID groups.

C. Set Copy to 15.

D. Increase the VSP G800 cache size to improve the application cache hit rates.

Which three statements are true regarding a VSP G400 configuration for a Microsoft Exchange Server environment? (Choose three.)

A. RAID 1+0 is a recommended RAID level for the database volumes.

B. RAID 6 is a recommended RAID level for the database volumes.

C. HDP is a recommended configuration for database volumes.

D. Parity group concatenation is recommended.

E. Microsoft JetStress testing should be used to validate the required performance.

For which two purposes is the SVP Performance Monitor suitable? (Choose two.)

A. Reporting by device owner

B. Annual trend analysis

C. Real time observations

D. A reference for verifying the accuracy of other performance tools

For a VSP G1000 system serving a mission critical interactive workload, which two statements are true about VSD failover? (Choose two.)

A. The VSD receiving the workload of a failed VSD is not pre-determined.

B. Providing reserved capacity to accommodate failure is a requirement when planning for capacity for normal operations.

C. The workload of a failed VSD board always transfers to its redundant partner VSD board.

D. The workload of a failed VSD board is dynamically redistributed among surviving VSD boards.

An experienced system administrator reports near maximum MPB utilization with VSP G400 arrays operating in a GAD pair. Each array is supporting 100K IOPS with a 50% read workload. The MPBs should be capable of supporting more than 200K IOPS with this profile according to the basic array sizing tools.

Which two statements are correct in this scenario? (Choose two.)

A. Cache mirroring between the two G400 arrays generates an extra MPB load which is not recorded in Hitachi Tuning Manager.

B. Each G400 array is also processing 50K duplex write IOPS from the other G400.

C. The duplex GAD writes are changing the overall read/write I/O profile and the extra parity operations are causing the high MPB utilization.

D. The internal array queue management scheme for GAD write operations causes MPB utilization to be doubled.
