Modular Foundations (HH0-120) Exam Updates...

Sent to me last week, here's a breakdown of the Modular Foundations exam (HH0-120):

I've received reports of questions relating to the old Thunder series. This concerns me, because we haven't really taught the 9500 series since 2006 or so. In old braindumps, I've found a couple of 9500-series questions:

A customer is using a 9585V storage array and is evaluating whether to upgrade to an AMS500
for performance reasons. Which statement is true?
A. The AMS500 supports larger drive sizes.
B. The AMS500 provides more back-end loops.
C. The AMS500 supports faster back-end loops.
D. The AMS500 supports faster Fibre Channel host connections.
Answer: D

For reference here, the AMS500 is the older version of the AMS2300 (16 trays, 120 drives max). The reason "D" is the answer because AMS500 supported 4GB fibre ports where the Thunders only supported 2GB.

A customer has a high performance application that creates a bottleneck at the front-end ports.
Which two arrays are supported Hitachi Data Systems configurations? (Choose two.)
A. AMS500 with four4Gb/s host ports
B. AMS500 with eight2Gb/s host ports
C. Thunder 9585V with four4Gb/s host ports
D. Thunder 9585V with eight2Gb/s host ports
Answer: A,D

B is wrong because AMS500 supports 1-2-4 gig ports. C is wrong because the Thunders topped out at 2 gig ports.

The customer needs a modular storage system which supports 200 Fibre Channel disk drives and
at least four back-end loops. Which two arrays support this configuration? (Choose two)
A. AMS200
B. AMS500
C. WMS100
D. Thunder 9585V
Answer: B,D

Rule out A and C because the AMS200 and WMS100 are 8-tray, 120-drive max arrays.

An IT organization has an application that stores its data on a Thunder 9585V After externalizing
volumes, they have decided to move the application data from one subsystem to another
subsystem in order to improve performance. However, they cannot disrupt usage of the
application. Which software tool should they use for the volume migration?
A. HiCommand Device Manager
B. HiCommand Protection Manager
C. HiCommand Tiered Storage Manager
D. HiCommand Business Continuity Manager
Answer: C

Now, this is a question that is legit. The developer could have just as easily put Compellant or Clariion there instead of 9585V. The focus is on which product is correct.

A customer has a high performance application that creates a bottleneck in disk access functions.
Which array has the largest amount of back-end bandwidth?
A. AMS500
B. AMS200
C. WMS100
D. Thunder 9585V
Answer: D

This question assumes you know that the 9585V was the top-of-the-line, 2-rack array of its day, like the current AMS2500.
