Option D seems costly since binding an EIP to each instance would add up, but I'm not completely confident about the other options either.

I'm not sure about the SOAP API with My Domain - that seems a bit complex. Maybe the REST API would be a simpler approach?

I'm a bit confused by this one. The wording is a bit tricky, and I'm not totally sure which valuation method is being described. I'll have to read through the options carefully and see if I can eliminate any of them.

As a network admin, I'm cringing at the thought of option C. Exposing those instances directly to the internet? No way, that's a big security no-no.

Option D might work, but binding an EIP to each instance could get expensive. Better to use a single bastion host as suggested in option B.

Haha, option A is a classic. 'None of these answers are correct' - that's the kind of trick question I hate on these exams!
