Which of the following describes a characteristic of data at rest?

A characteristic of data at rest is that it is stored in a stable environment. Data at rest refers to any data that is not actively being used or processed; it is idle and typically stored on a physical or virtual storage medium, such as hard drives, databases, or cloud storage. This type of data remains in a fixed location until it is needed for access or processing.

In a stable environment, data at rest is maintained securely and is protected from unauthorized access and vulnerabilities. This stability usually involves measures like encryption, access controls, and regular maintenance to ensure the integrity and availability of the data over time. The other choices present failed interpretations of data at rest, highlighting characteristics that do not align with its definition. For instance, data at rest is not constantly changing, as it is in a state of inactivity, nor is it inherently accessible from multiple devices without appropriate management, and it certainly requires backups to prevent data loss.
