The Certkiller administrator is in the process of configuring a new RAID array and wants to know which of the RAID levels is a RAID 0 array striped across RAID 5 elements?

A.
RAID 5+1

B.
RAID 5+0

C.
RAID 0+5

D.
RAID 5+3

Explanation:
The RAID 5+0 implementation is a RAID 0 array striped across RAID

5 elements used to provide better fault tolerance than the single RAID 5 level does.
Incorrect Answers:
A: RAID 5+1 is used to includes mirroring, combined with block striping with distributed parity.
C: The RAID 0+5 implementation is used to form large arrays by combining the block striping and parity features of RAID 5 with the straight block striping of RAID 0.
D: The RAID 5+3 implementations is a combination of RAID 0 and RAID 3 and is effectively a configuration of striped array (RAID 0) whose segments are essentially RAID 3 arrays.
