RAID Recovery Course - Parity Analysis Test


Parity is a special function calculated over data blocks


Choose the correct statement



Choose the property of XOR function due to which "mirrors are always even"



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




Choose the property of XOR function due to which "you do not need to know the parity location when reconstructing a missing disk"



Check for what parity tests are done



Choose the correct statement



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



Choose the property of XOR function due to which "blank disks litter the parity analysis"



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