Compilation error? That sounds weird, but I guess anything's possible!

Wait, are you sure? I thought templates would take precedence.

Okay, let me walk through this. There's a template function `f(A &a)` and a non-template function `f(int &a)`. When we call `f(a)`, the non-template function should be the better match, so the output should be 2.

Ah, I see what's going on! The more specific `f(int &a)` function will be called, so the output should be 2. I'm confident I can solve this one.

Hmm, I'm a bit confused. The code seems straightforward, but I'm not sure which function will be called. I'll have to think this through step-by-step.

This looks like a tricky template function question. I'll need to carefully consider the function overloading rules and how they apply here.

Hmm, I'm a bit unsure about this one. The question mentions a "unique solution" for each question, so I'm not sure if this is the only correct answer or if there might be other ways to approach it.

I'm pretty confident about this one. The server is removed from the All Servers group, and scheduled backups for the server will be discontinued. Those are the two results I'm going with.
