- storage response time
- customer requirements
- host initiators utilization
Correct answer: AB
Question 2
You are evaluating storage system performance for an interactive workload. What are three appropriate criteria in this situation? (Choose three.)
- customer requirements
- throughput (MBs)
- elapsed time
- storage system response time
- resource utilization (% busy)
Correct answer: BCD
Question 3
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?
- approximately 570 IOPS
- approximately 1,140 IOPS
- approximately 1,530 IOPS
- approximately 2,280 IOPS
Correct answer: D
Question 4

- Online Analytical Processing (OLAP) data warehouse
- Online Transaction Processing (OLTP) with HDT
- large scale Consumer Video on Demand (CVOD)
- Virtual Desktop (VDI)
Correct answer: AB
Question 5
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?
- 2
- 3
- 4
- 6
Correct answer: C
Question 6
In a VSP G200 system, what are two advantages of RAID 1+0 compared to RAID 5/6 for random write workloads? (Choose two.)
- RAID 1+0 provides more useable capacity per for the same number of drives.
- RAID 1+0 has less processing overhead.
- Disk virtualization is lower.
- RAID 1+0 has more efficient pre-fetch operation.
Correct answer: AC
Question 7
Which three functions are performed by a VSP G1000 Virtual Storage Director (VSD)? (Choose three.)
- It executes host I/O requests.
- It calculates parity.
- It manages cache segment usage.
- It moves data to/from cache.
- It executes software such as HDP or copy products.
Correct answer: ACD
Question 8
Which two statements are true about the Active Flash feature on the VSP Midrange? (Choose two.)
- The Active Flash feature of Hitachi Dynamic Tiering monitors page access frequency in real-time, and immediately promotes pages that suddenly become busy.
- The Active Flash feature can be enabled on any HDT pool as long as Tier 1 of the Dynamic Tiering pool is composed of SSD or FMD drives.
- The Active Flash feature can be enabled on any HDP pool as long as the pool is comprised of SSD or FMD drives.
- The Active Flash feature of Hitachi Dynamic Tiering monitors page access frequency in real-time, and promotes pages based on a predefined schedule.

Question 10
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.)
- New writes will back up into the VSP G1000 cache.
- The host will see rapidly rising response times per request.
- The host will see a minor change in response times.
- The host will not be able to process new I/O requests.
Correct answer: CD
