RAID Recovery Course - Parity Analysis Test


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



A row of [A,B,P] blocks is even if


Choose the correct statement



Which parity function is usually used in a RAID5?




Choose the correct statement



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


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"



Next lesson - Entropy analysis
We have a mailing list in which we talk about interesting cases we encounter and share some tips and tricks.
