HCE-3700 by Hitachi Actual Free Exam Questions And Answers

Question 1

A customer with a VSP G1000 is using HDT with SAS 15K drives and external storage. The customer wants the daytime response-sensitive workload to benefit from tiering. They also want to minimize the impact of relocations on the daytime operation itself.
In this scenario, which action will satisfy the requirements?

A. Disable monitoring during daytime hours (9:00 AM to 5:00 PM)

B. Enable active flash so that all relocations can be completed in short bursts.

C. Use continuous mode with a 30-minute cycle time and define relocation during daytime hours (9:00 AM to 5:00 PM) with a low relocation speed.

D. Enable monitoring only during the daytime hours (9:00 AM to 5:00 PM) and only enable relocation at other times.

Question 2

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

A. It makes a path decision for every I/O request.

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

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

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

Question 4

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

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

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

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

Question 5

After moving an application to a dedicated HDP pool consisting of four array groups, RAID 6 and NL-SAS 6 TB drives, the user has noticed significantly high response times.
What information would be used to determine if the pool is configured appropriately in this scenario? (Choose two.)

A. array group utilization

B. total IOPS

C. percent random write ratio

D. average request size
