質問 1：
DP-Vol LUNs are taken from an HDP pool deployed with 128 disks (16x4D+4D RAID groups). Access is random read.
Which combination of FC paths, LUN Queue Depth, and number of DP-Vols will result in a per-disk queue of
4 within this pool?
A. 4 paths, a LUN Queue Depth of 16, and 32 DP-Vols
B. 4 paths, a LUN Queue Depth of 8, and 32 DP-Vols
C. 2 paths, a LUN Queue Depth of 8, and 32 DP-Vols
D. 2 paths, a LUN Queue Depth of 16, and 32 DP-Vols
正解：A
質問 2：
A customer complains about high response times. This occurs frequently with bursts of write I/O at 6,000 IOPS for 10 second periods during each minute. The write response is 60 ms during these 10 second periods.
The average IOPS rate reported by Hitachi Tuning Manager over 1 minute is 600.
In this scenario, what is the average response time over 1 minute?
A. 90 ms
B. 10 ms
C. 30 ms
D. 60 ms
正解：B
質問 3：

A. backup repository
B. customer relationship management
C. software development
D. customer service call taking and dispatch
正解：B,C
質問 4：
A customer using a small block interactive workload on a VSP G200 complains about poor application performance. They use an FC SAN which consists of 8 Gbps and 16 Gbps FC switches.
What are two causes of the performance issue? (Choose two.)
A. The host HBA has an insufficient queue depth setting.
B. Front-end ports of the VSP G200 are connected to the 8 Gbps FC switch.
C. The multi-pathing software uses round robin balancing algorithm.
D. The front-end FC ports are used by another bandwidth-intensive application.
正解：A,D
質問 5：
You are recommending RAID 6 to a customer for a non-database HDT pool.
What are two reasons for this recommendation? (Choose two.)
A. When capacity is pooled; the whole pool is affected when one parity group fails.
B. RAID 6 provides the most efficient use of system processor resources.
C. RAID 6 minimizes exposure to double disk failure.
D. RAID 6 provides the optimum overall performance of all RAID types.
正解：B,C
