RAID Recovery Course - Parity Analysis Test


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



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


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


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

Parity test for a Promise RAID6 gives:



When to apply parity analysis?
