Which of the following statements are true about distributed storage?

Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):

Distributed storage is a core concept in cloud computing and is emphasized in HCIA–Cloud Computing as a foundational technology for large-scale cloud platforms.

Option A is true. Distributed storage is designed for horizontal scalability, allowing storage capacity and performance to increase simply by adding more nodes.

Option B is true. Unlike traditional centralized storage systems, distributed storage typically runs on general-purpose x86 servers, reducing cost and improving flexibility.

Option C is false. Distributed storage does not rely on traditional RAID for data protection. Instead, it uses data replication or erasure coding, which are more suitable for large-scale distributed environments.

Option D is true. Distributed storage eliminates the need for dedicated controller enclosures or disk enclosures. Storage resources are directly provided by general-purpose servers, which aligns with cloud-native architecture principles described in HCIA materials.
