Which object represents a data repository type used for storage?

• A. Data Lakes
• B. Data Models
• C. AWS Data Streams
• D. Calculated Insights

Answer: (A)

Data lakes are designed as centralized repositories that store vast amounts of data in their native formats, suitable for long-term storage. They can hold structured, semi-structured, and unstructured data at scale and support schema-on-read, enabling flexible analysis later. This storage-focused role distinguishes them from other objects: data models describe how data is organized and related, AWS Data Streams are about moving data in real time, and calculated insights are outcomes derived from data rather than storage. Therefore, the object that represents a data repository type used for storage is the data lake.
