Which of the following is true about volumes in Docker?

Volumes in Docker are a key feature for data management, and the statement about them persisting data even when containers are removed is indeed accurate. Volumes are specifically designed to store data independently of the lifecycle of a container. This means that if a container is stopped or removed, the data stored in a volume remains intact and can be reused by new or existing containers.

This characteristic of volumes makes them particularly useful for applications that require data persistence, such as databases or file storage systems. By using volumes, you can ensure that your application data is retained across container deployments, enabling consistent access and stability of your application.

The other options relate to characteristics that do not accurately represent the functionality of volumes. For example, volumes are not temporary storage—rather, they are intended to provide lasting storage solutions. They also do not manage container networking, as networking is handled by other Docker components. Finally, volumes are not restricted to a single container's file system; they can be shared among multiple containers, allowing for flexible data management and collaboration between different services.
