Overlay driver

Bridge driver

11. What is the primary purpose of Docker volumes?

To provide persistent data storage independent of container lifecycle

To increase CPU performance

To limit network bandwidth

To encrypt container images

12. How do you inspect a volume's details and mount point?

Docker volume inspect volumename

Docker inspect volume volumename

Docker volume show volumename

Docker describe volume volumename

13. What is the main difference between volumes and bind mounts?
