Wait, are we really using ISO files for containers?

I don't think it's about ZIP archives or ISO files; that seems off, but I can't remember the exact process.

I feel like the answer might be B, since Docker uses layers to optimize image storage and retrieval.

I remember something about images being layered, but I'm not sure if it's multiple stacked images or something else.

Hmm, I'm not totally sure about this. I know Docker uses a layered file system, but I'm not certain if the images are actually retrieved as multiple stacked layers. I might have to review my notes on Docker image management to be sure.

I'm feeling confident about this one. The answer is definitely B. Docker containers are built from a series of read-only image layers that are combined to create the final container. That's how the image is retrieved from the registry.

The key here is understanding how Docker images are structured and stored. I think the answer is B - multiple stacked images are retrieved and layered on top of each other to create the final container.

Hmm, I'm a bit confused on this one. I know Docker uses a layered file system, but I'm not sure if the images are actually retrieved that way. I'll have to think this through a bit more.

I'm pretty sure the answer is B. Docker containers are built from multiple layers, so the image must be retrieved as a set of stacked images.

I'm not sure, but I think it makes sense that Docker would retrieve multiple images and stack them for the container.

This question is a real head-scratcher! I'm going to have to go with C - a flat hard disk image that gets mounted. Sounds like the most straightforward solution to me.
