RAID Recovery Course - Parity Analysis Test


Which parity function is usually used in a RAID5?




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



Parity is a special function calculated over data blocks


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



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




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"



Given that P is a parity block calculated over A and B data blocks


Choose the correct statement
