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
