3.3 Configuring a RAID

Question 1

What does RAID stand for?

Answer 1

Redundant Array of Independent Disks.

Question 2

What is the first step to configure RAID in the BIOS?

Answer 2

Enable RAID mode under SATA operations.

Question 3

What key is typically used to access the RAID controller during boot?

Answer 3

Ctrl+I (varies by system).

Question 4

What is the minimum number of drives required for RAID 0?

Answer 4

2 drives.

Question 5

What is the purpose of RAID 0?

Answer 5

Improves speed by striping data across drives, but offers no redundancy.

Question 6

What is the minimum number of drives required for RAID 1?

Answer 6

2 drives.

Question 7

What is the purpose of RAID 1?

Answer 7

Provides full redundancy by mirroring data across drives.

Question 8

What is the minimum number of drives required for RAID 5?

Answer 8

3 drives.

Question 9

What does RAID 5 use to provide redundancy?

Answer 9

Distributed parity.

Question 10

What is the minimum number of drives required for RAID 10?

Answer 10

4 drives.

Question 11

How does RAID 10 combine RAID 0 and RAID 1?

Answer 11

It stripes data across mirrored pairs for both speed and redundancy.

Question 12

What setting determines how data is divided across drives in RAID?

Answer 12

Strip size.

Question 13

When configuring RAID, what should you do after creating the RAID volume?

Answer 13

Verify volume details, such as RAID level, disk count, and capacity.

Question 14

What RAID level is best for redundancy with minimal disk requirements?

Answer 14

RAID 5 (requires at least 3 drives).

Question 15

Which RAID level provides the highest speed but no fault tolerance?

Answer 15

RAID 0.

Question 16

What RAID level should be used for financial data requiring full redundancy?

Answer 16

RAID 1.

Question 17

Which RAID level is ideal for video editing requiring high performance?

Answer 17

RAID 0.

Question 18

What is the advantage of RAID 10 over RAID 5?

Answer 18

RAID 10 offers better performance and redundancy but uses more storage capacity for mirroring.

Question 19

How do you check RAID configurations for errors in a simulated BIOS environment?

Answer 19

Recreate the RAID setup and verify disk assignments and settings.

Question 20

Why is it important to verify the minimum disk requirement for each RAID level?

Answer 20

Incorrect disk count can prevent the RAID array from being created.

Question 21

What should you refer to when BIOS settings differ between systems?

Answer 21

The motherboard manual.
