A database container is being recreated during an upgrade. The administrator wants the database files to persist across container recreation. Which approach ensures data persistence?

Use `docker export` to save the container filesystem before deletion.

Store data in the container's writable layer.

Use a named volume and mount it at the database's data directory.

Copy the data into the container image before running it.

A container named `api` is running but is not responding to health checks. The administrator wants to check the container's health status and recent logs. Which command provides both pieces of information?

`docker inspect api` and `docker logs api`

`docker top api` and `docker port api`

`docker ps` and `docker stats api`

`docker exec api healthcheck` and `docker logs api`

A developer pulled an image tagged `app:latest` from a public registry. Later, the developer pulls `app:latest` again and notices that the image ID is different. The developer wants to ensure the application runs with the exact same image as before. What should the developer do?

Reference the image by its digest, e.g., `app@sha256:...`.

Use `docker rmi app:latest` and then pull again.

Use `docker tag app:latest app:old` before pulling again.

Pull the image with `docker pull app:latest --disable-content-trust`.
