RAID Recovery Course - Content Analysis Test
Check what ratio of zeros helps exclude
stray disks
damaged disks
RAID5 disks
hotspare disks
blank disks
Check the possible RAID levels if parity analysis gives you 0% parity both for full disk set and exclusion combinations
RAID6
Regular RAID5
RAID5 with a missing disk
RAID5 with a hotspare disk
RAID0
Choose the RAID to which the ratio of zeros analysis can't be applied to
Mirror
RAID created over second hand non-blank drives
RAID created over brand-new disks
Check for what parity tests are done
all combinations with one disk excluded
each member disk
full disk set
all disk pairs
If in parity analysis you see 0% parity for full disk set and 100% parity with one disk excluded, what the array level is?
certain type of RAID6
RAID5 with a hotspare disk
RAID5 with a missing disk
full regular RAID5
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
If you see several mirror pairs in mirror map, it points to
RAID10
RAID5
RAID1
Ex-hotspare disk
Ratio of zeros analysis is applied to
single disk
set of RAID disks
Look at the picture on the right and guess RAID level

RAID1
RAID0
RAID10
Look at the picture on the right and guess the possible RAID level
full RAID 5 with a hotspare
RAID10
full RAID5
RAID 5 with a missing disk
