No way, D is incorrect. It can't be just 2008 R2!

I thought Docker clusters were limited to Linux only, but now I'm questioning if that's just for the community edition.

I feel like clusters can have a mix of OS types, but I can't recall if Windows 10 is included in that mix.

I think I remember that Docker EE supports multiple operating systems, but I'm not sure if it includes Windows Server 2019.

I think the key here is to focus on the specific version of Docker Enterprise Edition mentioned in the question. The supported operating systems may have changed from previous versions, so I'll need to be careful in my selection.

B seems like the most comprehensive answer. I mean, if I were running a Docker cluster, I'd want the flexibility to use different OSes, not just be stuck with Linux.

Haha, I bet the correct answer is not D. Who even uses Windows Server 2008 R2 these days? That's so last decade!
