Huawei Certified ICT Associate – Storage (HCIA-Storage) — Question 26

Which is the correct formation order of the following elements in RAID 2.0+?

Answer options

• A. LD -> CKG -> CK -> Extent -> LUN
• B. LD -> Extent -> CKG -> CK -> LUN
• C. LD -> CK -> CKG -> Extent -> LUN
• D. LUN -> CK -> CKG -> Extent -> LD

Correct answer: D

Explanation

The correct answer is D because in RAID 2.0+, the formation starts with LUN, followed by CK, then CKG, Extent, and finally LD. The other options incorrectly order the components, which disrupts the RAID structure and functionality.
