Which statement describes the purpose of Docker volumes?

The purpose of Docker volumes is to provide persistent storage for data generated and used by Docker containers. Unlike the container filesystem, which is ephemeral and tied to the lifecycle of the container, volumes exist independently and can be reused across multiple containers. This means that even if a container is removed, the data in the volume remains intact, allowing for data continuity and persistence.

Volumes also facilitate easier data sharing among containers and can be managed more effectively through Docker commands. They are commonly used for databases, application logs, and other forms of data that need to be retained beyond the lifecycle of a single container instance. This characteristic of volumes is crucial for applications that require data consistency and durability, ensuring that data is not lost when containers are stopped or removed.
