The Certkiller Administrator wants to know from the trainee which of the following RAID implementations provides improved performance combined with some degree of multiple-drive fault tolerance?
A.
RAID 0+5
B.
RAID 5+3
C.
RAID 5+0
D.
RAID 10
Explanation:
The RAID 10 provides improved performance combined with some degree of multiple-drive fault tolerance.
Incorrect Answers:
A: 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.
B: 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.
C: 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.
