Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use a Docker volume
Why this is correct
Correct. Volumes are managed by Docker and persist data.
- ✗
Store data inside the container filesystem
Why it's wrong here
Data inside the container is ephemeral and lost when the container is removed.
- ✗
Use a bind mount only for configuration files
Why it's wrong here
Bind mounts can be used but are not as portable; volumes are recommended.
- ✗
Set the container to always restart
Why it's wrong here
Restart policy does not preserve data; it only restarts the container.
