RAID Recovery Course - Content Analysis Test


Check parity-based RAIDs





Check for what parity tests are done




Parity test for a full regular RAID5 gives



Disks from the same RAID have the same ratio of zeros and average entropy


Is it needed to know RAID level to recover data?



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




Look at the picture and choose the possible variant



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




Look at the picture on the right and guess RAID level




Choose the RAID to which the ratio of zeros analysis can't be applied to
