Haha, this question is a real brainteaser. I bet the exam writer was just sitting there, cackling, 'Let's see who really knows their vSAN math!'

I'm not sure, but I think C) 1 * PFTT + 2 makes more sense based on the rationale provided in the question.

Clearly the answer is D. 2 * PFTT + 1. Why would you add 2 when you only need 1 spare host? Come on, people, think this through!

No, it's actually D) 2 * PFTT + 1. You need 2 additional hosts for failure tolerance.

Hmm, I was leaning towards C, but now I'm not so sure. Does the PFTT include the 'spare' host or not? This is tricky.

I'm pretty sure the answer is B. 2 * PFTT + 2 just makes the most sense to me. Why would you only add 1 when the PFTT is already the minimum required?

I think you might be right, B does seem like the most logical choice.
