HCE-3710 Exam Training Practice Tests (Hitachi Vantara Certified Expert

Question 1

A customer has chosen TrueCopy for their disaster recovery replication to minimize data loss. The solution must minimize any potential host performance impact.
What are two considerations for this hardware configuration?
(Choose two.)
Response:

A. MCU and RCU disk configurations should be identical. B. Production hosts should be removed from the RCU. C. Both MCU and RCU should have additional disks added as journal volumes. D. The RCU should have the same number of replication ports as the MCU.

Correct Answer: A,D

Question 2

A customer is using ShadowImage(SI) on a Virtual Storage Platform (VSP) for a point-in-time copy. The SI P-Vol resides in a SAS HDP pool and the SI S-Vol resides in a SATA HDP pool. During resychronization, the VSP cache write pending hits 60 percent utilization in CLPRO.
What are two ways to reduce the resynchronization impact on host performance?
(Choose two.)
Response:

A. Keep the SI pairs in PAIR state. B. Put the SI S-Vols in a separate CLPR. C. Run an SI resync during non-peak hours. D. Run an SI quick split.

Correct Answer: B,C

Question 3

What are two benefits of using ShadowImage on an HUS 150?
(Choose two.)
Response:

A. S-Vol size can be larger than the P-Vol. B. It provides up to 9 copies. C. It provides up to 8 copies. D. S-Vol can be cascaded off a TrueCopy volume

Correct Answer: C,D

Question 4

What are two concerns when deploying data collectors for sizing replication?
(Choose two.)
Response:

A. relevant volumes not included in data collection B. read IOPS data is not collected C. read MB/sec data is not collected D. improper duration of data collection

Correct Answer: A,D

Question 5

Which sizing metric is directly affected by the peak write MB/sec measurement provided by the workload analysis?
Response:

A. selection of DWDM or IP-based connectivity B. shared memory C. cache D. telecommunication bandwidth

Correct Answer: D

Question 6

A customer is concerned with maintaining real-time recovery volumes across several hundred kilometers with minimal impact to host response time.
Network infrastructure between the two facilities is subject to periodic bandwidth reductions due to surges in overall network activity. The customer is unwilling to invest in additional network capacity.
Which replication approach should you recommend for this application?
Response:

A. In-system replication to virtualized storage B. Journal-based asynchronous replication C. Synchronous replication D. Mediated point-in-time replication

Correct Answer: B

Question 7

Your customer is determined to conduct disaster recovery testing with the Hitachi Universal Replicator volume in a read/write state at the secondary site. The test will take 4 hours and they have a 4-hour RPO.
Which two impacts will this have on their ability to recover from a disaster?
(Choose two.)
Response:

A. The customer will be within their RPO at the end of the test. B. The customer will exceed their RPO at the end of the test. C. The customer will be at risk from a disaster at the primary site. D. The customer will have protection from logical corruption during the test.

Correct Answer: B,C

Question 8

A customer's production facilities are located several hundred kilometers apart. The customer is cost conscious and wants to reduce recurring expenses.
Which two replication strategies would be used to balance recoverability versus bandwidth costs?
(Choose two.)
Response:

A. mediated point-in-time copy replication B. synchronous replication C. in-system replication to virtualized storage D. journal-based asynchronous replication

Correct Answer: A,D
