Huawei Certified ICT Associate – Storage (HCIA-Storage) — Question 42
Which statement is true about RAID 2.0+?
Answer options
- A. RAID 2.0+ has a higher RAID overhead than traditional RAID types.
- B. Chunks belonging to a file will never be written on the same physical disk.
- C. RAID 2.0+ allows for a complete enclosure to fail without causing data loss.
- D. With RAID 2.0+ it is supported to select no hot spare disks.
Correct answer: D
Explanation
The correct answer, D, is accurate because RAID 2.0+ supports configurations without any hot spare disks, allowing for flexibility in disk management. Options A and C are incorrect as RAID 2.0+ typically aims to reduce overhead and does not inherently allow an entire enclosure to fail without data loss. Option B is also incorrect since chunks of a file can be written on the same physical disk in certain RAID configurations.
