ReclaiMe Data Recovery Training

RAID Recovery Course - Overall Test

Where is RAID metadata stored?

at the end of the member disk
at the beginning of the member disk
anywhere, depending on the implementation specifics

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

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

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

Full RAID5
Full RAID 5 with a hotspare
RAID10
RAID 5 with a missing disk

Check what you can do with entropy analysis

spot the disks which do not form a parity-based array
detect the first disk in the RAID
notice that start offset doesn't equal zero
spot the disks which do not belong to the RAID in question

When to apply entropy analysis?

after content analysis
between zero and mirror analysis
before content analysis

What is the recommended approach to check the quality of RAID recovery

check large files, larger than several block sizes
folder tree check is enough
check many small files, smaller or equal to block size

When to apply parity analysis?

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

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

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
yes, all the data can be recovered
