Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
All container changes are written directly back to the read-only image layer
Why it's wrong here
Image layers remain strictly read-only.
- ✓
The container has its own writable scratchpad layer separate from the image
Why this is correct
An overlay writable layer is provisioned for the running container instance.
- ✗
Data persists automatically across host reboots and container deletions
Why it's wrong here
Persistence requires volumes or bind mounts.
- ✓
Data written to the container layer is lost when the container is removed
Why this is correct
Changes to the container file system are ephemeral.
- ✗
Host files are automatically synchronized into the container storage
Why it's wrong here
Synchronization does not happen automatically.
