I recall reading that having the same configuration for all backend servers isn't strictly necessary, so D seems off to me.

I practiced a similar question, and I think C is misleading. I believe backend servers can be in different scaling groups as long as they are linked to the same SLB.

I’m not entirely sure, but I feel like the operating system requirement in option B could be a bit too strict. I think different OS might still work together.
