The Certkiller administrator wants to know from you witch of the following RAID implementations will use half of what ever storage size you have solely for redundancy purposes?
A.
RAID 1+0
B.
RAID 0+1
C.
RAID 5+0
D.
RAID 0+5
Explanation:
The RAID 1+0 combination applies RAID 1 first, after splitting the eight drives into four sets of two drives each using half the storage effectively.
Incorrect
Answers:
B: The RAID 0+1 combination of implementations uses RAID 0 strictly because of its high performance and RAID 1 for its high fault tolerance.
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.
D: 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.
