RAID level 10 is created by combining which of the following?
A.
level 0 (striping) with level 1 (mirroring).
B.
level 0 (striping) with level 2 (hamming).
C.
level 0 (striping) with level 1 (clustering).
D.
level 0 (striping) with level 1 (hamming).
Explanation:
RAID 10, also known as RAID 1+0, combines disk mirroring and disk striping to protect data.
A RAID 10 configuration requires a minimum of four disks, and stripes data across mirrored pairs. As long as
one disk in each mirrored pair is functional, data can be retrieved. If two disks in the same mirrored pair fail, all
data will be lost because there is no parity in the striped sets.
RAID 10 provides redundancy and performance, and is the best option for I/O-intensive applications. Onedisadvantage is that only 50% of the total raw capacity of the drives is usable due to mirroring.
Incorrect Answers:
B: Level 0 (striping) is combined with level 1 (mirroring), not level 2 (hamming).
C: Level 1 is mirroring, not clustering.
D: Level 1 is mirroring, not hamming.http://searchstorage.techtarget.com/definition/RAID-10-redundant-array-of-independent-disks
