Question 1

What does RAID stand for?

Answer 1

Redundant Array of Independent Disks

Question 2

Answer 3

striping

Question 4

What is the primary benefit of RAID 1?

Answer 4

Answer 6

True

Question 7

What is the main disadvantage of RAID 0?

Answer 7

Question 8

In RAID 5, how is data distributed across the disks?

Answer 8

Data and parity information are striped across all disks.

Question 9

What is the primary purpose of parity in RAID?

Answer 9

To provide data recovery in case of a disk failure.

Answer 13

False

Question 14

What is a common use case for RAID 1?

Answer 14

Data redundancy for critical applications

Question 15

What does RAID 0 not provide that RAID 1 does?

Answer 15

Data redundancy

Question 16

What happens if a single disk fails in a RAID 5 setup?

Answer 16

The array can operate in a degraded mode, but data is still accessible.

Question 17

What is the main advantage of RAID 6 over RAID 5?

Answer 17

RAID 6 can tolerate the failure of two disks.

Question 18

Which RAID level is best for applications requiring high read speeds?

Answer 18

RAID 0

Question 19

True or False: RAID 1 is less expensive than RAID 0.

Answer 19

False

Question 20

What does the ‘N’ in RAID N refer to?

Answer 20

The number of disks in the array

Question 21

What is the purpose of a RAID controller?

Answer 21

To manage the RAID configuration and data distribution.

Question 22

What is a common drawback of using RAID?

Answer 22

Increased complexity in setup and management.
