ReclaiMe Data Recovery Training

RAID Recovery Course - Overall Test

Is it possible to recover data if one of the member disks in a RAID5 failed?

no
yes, but only part of the data is recoverable
yes, all data is recoverable
depends on which disk failed

Is it possible to recover data if one of the member disks in a RAID10 failed?

depends on which disk failed
no
yes, but only part of the data is recoverable
yes, all data is recoverable

Look at the picture on the right and guess the possible RAID level

RAID 5 with a blank disk
RAID6 with a missing disk
Full RAID 6 with a hotspare
Full RAID6

What is the correct order of the content analysis stages in ReclaiMe Pro?

parity analysis, ratio of zeros, mirror analysis
mirror analysis, ratio of zeros, parity analysis
ratio of zeros, mirror analysis, parity analysis

When you should do parity analysis?

after entropy analysis
always
when content analysis is done but RAID level is still unknown

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

yes, but only half of the data can be recovered
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

When to apply parity analysis?

before zero and mirror analysis
after entropy analysis
after zero and mirror analysis
between zero and mirror analysis

When to apply entropy analysis?

between zero and mirror analysis
after content analysis
before content analysis
