Question 1

In a database environment, the system administrator complains that high write response times are triggering frequent automated alerts. However, utilization for processor, paths, and array groups is low. Database users are not complaining. What causing this problem?

AThe RAID level is inappropriate.

BThe storage system has too few processors.

CThe storage media devices are too slow.

DAsynchronous destaging of writes occurs in bursts.

Answer : D

Question 2

How does the HDLM Extended Round Robin algorithm impact sequential I/O?

AIt continues to use the same path for a user-specified count of sequential I/O requests.

BIt remembers a user-determined number of addresses to better implement sequence detection for the storage.

CIt buffers and reorders I/O requests to improve sequence detection by the storage.

DIt makes a path decision for every I/O request.

Answer : A

Question 3

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

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

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

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

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

Answer : B, C

Question 4

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?

APut all of the databases in a single HDT pool.

BPut each database in its own HDT pool.

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

DPut 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.

Answer : A

Question 5

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?

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

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

CSet Copy to 15.

DIncrease the VSP G800 cache size to improve the application cache hit rates.

Answer : A

Question 6

On a VSP G1000, the maximum I/O Request Limit for an external initiator port has been exceeded. What are two consequences of this activity? (Choose two.)

ANew writes will back up into the VSP G1000 cache.

BThe host will see rapidly rising response times per request.

CThe host will see a minor change in response times.

DThe host will not be able to process new I/O requests.

Answer : C, D

Question 7

Immediately after migrating to a new HDT pool, Hitachi Tuning Manager shows that Tier 1 SSD, Tier 2 SAS, and Tier 3 NL-SAS are not busy for performance but Tier 1 and Tier 2 are over utilized for capacity. From this analysis, which action should be performed?

ARe-asses after HDT performs page migration cycles.

BAdd more drives to Tier 1.

CAdd more drives to Tier 1 and Tier 2.

DRemove the SSD tier.
