Which storage type provides access using Amazon S3 APIs?

• A. San
• B. Nas
• C. Das
• D. Object

Answer: (D)

Object storage is designed around accessing data via API calls, such as the Amazon S3 REST API. In this model, data is stored as discrete objects within a flat namespace, each object carrying its own data and metadata and accessed by a unique key through HTTP-style requests (for example, creating, retrieving, listing, or deleting objects in buckets). This makes it ideal for scalable, internet-facing storage that is consumed by applications through S3-compatible endpoints.

In contrast, SAN and DAS provide block-level access, meaning the storage is presented as raw blocks to a server and used by the operating system as a disk or LUN. NAS delivers file-level access over network file protocols like NFS or SMB, where data is accessed as files within a filesystem. Because S3 APIs are specifically designed for object storage, the storage type that provides access using Amazon S3 APIs is object storage.
