Question 2

Called a striped volume and is preferred over spanning

Answer 2

RAID 0

Question 3

A type of mirroring that duplicates data on one drive to another drive and is used for fault tolerance. If one drive fails, the other continues to operate and data is not lost.

Answer 3

RAID 1

Question 4

Stripes data across three or more active drives and uses parity checking; if one drive fails the others can re-create the data stored on the failed drive by using the parity information.

Answer 4

RAID 5

Question 5

What are some benefits of RAID 5?

Answer 5

• data is not duplicated which makes better use of

- drives increase performance and provide fault tolerance

Question 6

A combination of RAID 1 and RAID 0; takes at least 4 disks and data is mirrored across pairs of striped disks

Answer 6

RAID 10 (one zero)
