I practiced a question similar to this, and I think Shared Nothing and Shared Everything were definitely included, but I can't remember if Dedicated was mentioned.

Whoa, this is a tricky one! I'm pretty sure Shared Nothing and Shared Everything are the right answers, but I'm not too sure about the third one. Gotta do some more studying on database architectures I guess.
