No way, --publish is the only way to go!

I thought EXPOSE was just for documentation?

I could be wrong, but I feel like both options might not fully achieve the goal. Maybe there's more to it than just those commands?

This reminds me of a practice question where we had to decide between EXPOSE and --publish. I think --publish is the correct answer here.

I'm not entirely sure, but I remember something about EXPOSE not actually mapping ports. It might not work as expected.

I think using --publish is definitely the way to go for making a container reachable from the host. EXPOSE seems more like a declaration.

This seems like a tricky one. I'll need to carefully weigh the options and think through the pros and cons of each approach.

This seems like a straightforward question about getting a comprehensive list of SAP applications. I think the SAP Solution Manager would be the best option to use here.

Hmm, I'm not entirely sure about this one. I'll need to carefully consider each option and think through the potential benefits of a structured training plan.

Wait, I'm not totally sure. There are so many similar acronyms. Is this the sports medicine one or first aid technique?

I think option D seems off; if the price increases, shouldn't that help with reaching the profit target? I'm really confused about that one.

I definitely remember using `src==` and `dst==` in our last lab, but I'm confused if that's the right choice here or not.
