ReclaiMe Data Recovery Training

RAID Recovery Course - Overall Test

When to apply parity analysis?

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

When to apply entropy analysis?

after content analysis
before content analysis
between zero and mirror analysis

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

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

What does content analysis help determine?

disk order
RAID level
block size

When you should do parity analysis?

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

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

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

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

Look at the picture on the right and choose the most complete configuration

full 4-disk RAID5, 16 KB block size
full 4-disk RAID5, 64 KB block size
4-disk RAID5 with one disk missing, 32 KB block size
full 4-disk RAID5, 32 KB block size

NASes only use software RAID

true
false
