Wait, can you really access them without --link?

B is the way to go! EXPOSE or --publish works.

I don't think --link is the right choice anymore; it seems outdated compared to the other options.

I feel like network connect was mentioned in a different context, but I can't recall how it applies to this question.

I remember we talked about using EXPOSE in class, but I'm not sure if that's enough on its own.

I think we also practiced using --publish to map ports, which might be the right answer here.

Wait, was it oxygen scavengers or something else? I'm drawing a blank here. Maybe I should eliminate the options that don't sound right and see if that helps me narrow it down.

Okay, let me think this through. I believe the key is to control the allowed state transitions, so modifying the Records State Transition table seems like the most direct way to add that restriction. I'll make sure to double-check the details, but that's my initial strategy.

Isn't the 'production process' more about operations? I feel like it's not a part of the marketing mix directly.

Ah, I've seen this type of issue before. My money's on the IPv4 address mismatch. That's usually the first thing to check when OSPF neighbors can't form a full adjacency.
