RAID Recovery Course - RAID Levels Test

Is it possible to recover data form a RAID0 in which one of the member disks failed?

yes, all the data can be recovered
no, for all practical purposes it is impossible since all you get are files no larger than block size
yes, but only half of the data can be recovered

Which controller uses non-typical RAID6 layout – wide pace?

HP SmartArray
Promise
LSI

What minimum disk number is required for a RAID1E?

two
four
five
three

What RAID type is shown on the right?

RAID1E

RAID1E is a variation of RAID10 over odd number of disks

true
false

How data is distributed to disks in a JBOD

data is written to the first disk until it is half-full, then to the next disk until it is half-full, and so on
data is written to the first disk until it is full, then to the next disk

All block RAIDs are redundant

true
false

What minimum number of disks is required for a RAID1?

three
four
one
two

RAID5 is

redundant non-block array
non-redundant non-block array
redundant block array
non-redundant block array
