About This Quiz
CompTIA Certifications Quizzes & Trivia

Test your knowledge of RAID Levels and storage configuration strategies. This quiz evaluates your understanding of RAID 0, 1, 5, 6, and 10\u2014essential for CompTIA A+ and Storage+ certification. Learn how different RAID Levels provide redundancy, performance, and fault tolerance in enterprise environments.

2.

What first name or nickname would you like us to use?

You may optionally provide this to label your report, leaderboard, or certificate.

2. RAID 10 is often called ____ because it mirrors pairs of striped sets.

Submit

3. Which RAID level balances performance, capacity, and redundancy for most enterprise use?

Submit

4. True or False: RAID 6 provides better redundancy than RAID 5.

Submit

5. What is the primary disadvantage of RAID 0?

Submit

6. True or False: RAID 5 can continue operating with one failed drive.

Submit

7. Which RAID level is most suitable for databases requiring high availability?

Submit

8. RAID 6 uses ____ independent parity schemes for enhanced protection.

Submit

9. What is the storage efficiency of RAID 1 with two drives?

Submit

10. True or False: RAID 0 provides data redundancy.

Submit

11. What does RAID 10 combine?

Submit

12. RAID 6 can tolerate the simultaneous failure of how many drives?

Submit

13. Which RAID level uses block-level striping with distributed parity?

Submit

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

Submit

15. RAID 5 uses ____ parity blocks distributed across drives.

Submit

16. RAID 0 provides which primary benefit?

Submit

17. Which RAID level offers the best performance for read-heavy workloads?

Submit

18. RAID 1 is also known as ____ .

Explanation

RAID 1 is also known as mirroring because it stores an identical copy of the data on two or more drives. This provides redundancy, so if one drive fails, the data remains available on the other drive(s), improving fault tolerance but requiring at least two drives.

Submit

19. RAID 1 writes data to ____ drives simultaneously.

Explanation

RAID 1 writes data to two or more drives simultaneously by creating identical copies of the data on each drive. This mirroring ensures that if one drive fails, the same data is still available on the remaining drive(s), providing high data reliability and fault tolerance.

Submit

20. RAID 5 requires at least ____ drives to function.

Explanation

RAID 5 requires a minimum of three drives to function. It uses block-level striping with distributed parity, which spreads data and parity information across all drives. This allows the array to continue operating even if one drive fails, providing both improved performance and fault tolerance.
