RAID Recovery Course - Parity Analysis Test


What is calculated in parity analysis?



Check for what parity tests are done



Which parity function is usually used in a RAID5?




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



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


Parity is a special function calculated over data blocks


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



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