What term is used to describe a layer of archive storage?

• A. Tier
• B. Tiering
• C. Array
• D. Segment

Answer: (A)

In storage, data is organized into tiers, with each tier representing a layer that has its own performance, capacity, and cost characteristics. An archival needs layer is designed for long‑term retention at low cost, even if access times are slower. That layer is described as a tier. Tiering refers to moving data between these layers, not naming the layer itself. An array is a hardware collection of drives, and segment isn’t the standard term for a storage layer. So the best answer is tier.
