Goal: Confirm you can predict what a container keeps, choose between a volume and a bind mount, and keep data out of the images you push.

Four questions: three on Module 7 and one from Module 5. Every answer explains itself, right or wrong.

A container writes a log file to /tmp/app.log. Which of these deletes it?docker stop, then docker startThe app crashes and Docker restarts itRemoving the container and starting a new one from the same image

While developing, you want a container to serve the HTML files you're editing, without rebuilding after every change. What do you use?A bind mount of your project folderA named volumeA COPY line in the Dockerfile

You bind-mount an empty folder from your machine at /app, where your image keeps its code. The container fails with a file-not-found error. Why?The mount hides the code the image had at /appThe mount deleted the code from the imageMounts change the container's working directory

From Module 5: your app keeps uploads on a volume at /data. You push version 1.1.0 of its image to a registry and a server runs it. Are the uploads in the pushed image?Yes: the push copies everything the container hadNo: the registry gets the image's layers, not the volumeOnly if you tag it latest

Retry as often as you like.
