I'm just going to put in a random answer and hope the exam grader is in a generous mood today. Hadoop is confusing enough without these trick questions!

Is there an option for 'all of the above and none of the above'? That's usually how these Hadoop questions work.

Well, at least this question isn't as confusing as the one about Yarn's resource negotiation. I'll go with C, sounds the most plausible.

Hmm, I'm torn between A and C. The block pool management and physical vs. logical space sharing aspects are tricky.
