A minimum of 19 correct answers is required to pass.Congratulations, you passed the FlashSystem
Fundamental Concepts quiz.
Question 1
Correct
1.00 points out
of 1.00
What is a unique advantage of Distributed random array of inexpensive disks (RAID) 1 verses Traditional RAID 1
in terms of flexibility?
Select one:
The RAID groups must contain an even number of drives up to a total of 14 drives.
The RAID groups must contain an odd number of drives up to a total of 15 drives.

You can have any number of drives up to a total of 16.
There is no advantage with Distributed RAID (DRAID) or Traditional RAID (TRAID) when dealing with level 1.
Question 2
Correct

of 1.00
What is the only model of FlashSystem that cannot participate in a HyperSwap configuration?
Select one:

FlashSystem 5015
FlashSystem 5035
FlashSystem 9500
FlashSystem 7300
Question 3
Correct
1.00 points out
of 1.00
Dynamic Distributed random array of inexpensive disks (DRAID) Expansion enables the size of a DRAID group to
be non-disruptively increased by how many drives at a time?
Select one:

Up to 12
Up to 8
Up to 6
Up to 10
Question 4
Correct
1.00 points out
of 1.00
What is a major advantage of Distributed random array of inexpensive disks RAID verses Traditional RAID?
Select one:
The spare drive is part of the active RAID group and delivers performance and value on a daily basis.

DRAID 1 can be configured without a spare while TRAID 1 always requires a spare.
You never need a spare when using Distributed RAID (DRAID) 5 versus Traditional RAID (TRAID) 5, and
that saves money for the client.
The spare is not part of the active RAID group and it remains pristine and ready for use when it is
required.

Question 17
Incorrect
0.00 points out
of 1.00
Drive Write Per Day (DWPD) measurements were important at one time. What development has largely
rendered DWPD measurements pointless?
Select one:
Quad-level cell (QLC) flash does not function the same way as triple-level cell (TLC) or single-level cell (SLC)
flash thereby rendering DWPD comparisons pointless.
Flash drive sizes have become large enough that it is nearly impossible to write the full capacity of a drive in
a single day.
DWPD is still extremely important and should be part of every client discussion in a sales opportunity.
Flash has become so reliable that it no longer makes sense to focus on potential DWPD values.
