Binding EIPs to each instance? That's gonna get expensive fast.

I disagree, modifying the security group is risky!

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 practiced a similar question where using a bastion host was the best approach, so I think B is the correct answer here too.

I'm not entirely sure, but I feel like modifying the security group policy in option C could expose the instances to risks.

I remember discussing bastion hosts in class, and I think option B sounds right since it allows secure access to multiple instances.

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!

I wouldn't go with option C. Exposing all instances to the internet is a security risk we should avoid at all costs.

Option B seems like the most secure and cost-effective solution. Using a bastion host is a common practice for remote management without exposing all instances directly to the internet.
