Which scenario best illustrates data at rest?

Data at rest refers to inactive data stored physically in any digital form (such as databases, data warehouses, or files) that is not actively being used or transmitted. It is important to recognize that data at rest is typically characterized by its stability and security needs since it is not currently being processed or moved.

In this context, the scenario that best illustrates data at rest is a database storing customer information. This situation clearly represents data that is stored and not being actively manipulated or transmitted, thereby aligning perfectly with the definition of data at rest. The database holds the customer information securely until it is needed for processing or retrieval, but when it is simply stored, it is indeed a prime example of data at rest.

In contrast, the other scenarios involve data that is not in a resting state; uploading a file indicates it is in transit, a document being edited shows active manipulation, and streamed data is continuously moving from one point to another. These scenarios reflect data in motion rather than data that is static and stored.
