But what about build complexity? Seems risky.

I feel like there might be other advantages too, but optimizing images does seem like a valid point for multi-stage builds.

This sounds familiar; I practiced a question about multi-stage builds last week, and I think the selective copying was mentioned as a key benefit.

I'm not entirely sure if that's the main advantage. I remember something about reducing image size, but I can't recall the details.

I think multi-stage builds do help in optimizing images by copying only what's necessary, so I would lean towards "Yes."

VARIANT seems like the most likely answer here. It's a data type that can hold multiple data structures, right? I'm going to go with that.

Hmm, I'm a bit confused by this question. I'm not sure I fully understand what a constructive obligation is. I'll need to think it through and try to eliminate the options that don't seem to fit the definition.

This seems like a straightforward question about referential integrity. I think the answer is Restricted, since we want to prevent the deletion of records in Table1 if there are related records in Table2.

I remember learning about DNS-based hub resolution as a backup method, but I can't recall if it's the only one.
