Selected Answer: A
Key requirement it "maximize availability while minimizing the operational overhead" of 200 zones to process million requests R53 is designed exactly to do this and supports zone import functionality so literally does the job of their EC2 servers but much better so BCD become "overhead" by default. I doubt D will work.

B, C and D would not "maximize availability" (not HA) and also not minimize the operational overhead.

No, "Desired capacity 1" meaning that usually only 1 server would run, but they want to "maximize availability". And operating EC2 servers would not be "minimizing the operational overhead that is related to the management of the two servers."
