Hitachi Vantara HCE-3700 (Performance Architect) Sample Questions:

01. In a VSP G200 system, what are two advantages of RAID 1+0 compared to RAID 5/6 for random write workloads?
(Choose two.)
a) RAID 1+0 provides more useable capacity per for the same number of drives.
b) RAID 1+0 has less processing overhead.
c) Disk virtualization is lower.
d) RAID 1+0 has more efficient pre-fetch operation.
02. 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.
03. A high level of writes to external storage is backing up into a VSP G1000 cache, creating a high write pending problem that is affecting other workloads. Which three actions will help to minimize this problem?
(Choose three.)
a) Add more cache to the enterprise storage system.
b) Add more cache in the external storage.
c) Quarantine the LUNs in a separate cache partition.
d) Set Cache Mode to “Disabled” for the external LUNs.
e) Address the throughput constraints in the external storage.
04. You are evaluating storage system performance for an interactive workload. What are three appropriate criteria in this situation?
(Choose three.)
a) customer requirements
b) throughput (MBs)
c) elapsed time
d) storage system response time
e) resource utilization (% busy)
05. What are two appropriate criteria for evaluating a batch job performance?
(Choose two.)
a) storage response time
b) host initiators utilization
c) elapsed time and/or throughput (MBs, IOPS)
d) customer requirements
06. A 10K RPM Small Form Factor 600 GB disk drive has a 3 ms average rotational latency and a 4 ms average seek time. How many random read IOPS would you expect from a 4D+4D RAID group using these drives before any consideration for cache hits or queuing optimization benefits?
a) approximately 570 IOPS
b) approximately 1,140 IOPS
c) approximately 1,530 IOPS
d) approximately 2,280 IOPS

(Choose two.)
a) Online Analytical Processing (OLAP) data warehouse
b) Online Transaction Processing (OLTP) with HDT
c) large scale Consumer Video on Demand (CVOD)
d) Virtual Desktop (VDI)
09. You are recommending RAID 6 to a customer for a non-database HDT pool. What are two reasons for this recommendation?
(Choose two.)
a) RAID 6 minimizes exposure to double disk failure.
b) RAID 6 provides the optimum overall performance of all RAID types.
c) RAID 6 provides the most efficient use of system processor resources.
d) When capacity is pooled; the whole pool is affected when one parity group fails.
10. How many back-end disk operations are normally required to complete a small block random write operation to a LUN on a RAID 5 group?
a) 2
b) 3
c) 4
d) 6
