ReclaiMe Data Recovery Training

RAID Recovery Course - Content Analysis Test

Check what content analysis in ReclaiMe Pro includes

analysis of different file types
ratio of zeros
mirror analysis
ratio of files to folders

What is the first step in RAID recovery?

entropy analysis
parity analysis
content analysis

Look at the picture on the right and check the possible RAID level(s)

full RAID5
RAID 5 with a missing disk
RAID0
RAID10

Rows in a parity-based RAID are always even

true
false

Check the possible RAID levels if parity analysis gives you 0% parity both for full disk set and exclusion combinations

Is it needed to know RAID level to recover data?

yes
no
only if you need a full scale RAID recovery (RAID metadata is severely damaged)

1-5% ratio of data similarity points to

different disks
mirror pair
ex-hotspare disk

If in parity analysis you see 0% parity for full disk set and 100% parity with one disk excluded, what the array level is?

RAID5 with a missing disk
certain type of RAID6
RAID5 with a hotspare disk
full regular RAID5

Check for what parity tests are done

all disk pairs
all combinations with one disk excluded
full disk set
each member disk

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

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

We have a mailing list in which we talk about interesting cases we encounter and share some tips and tricks.
