Wait, is a bastion host really that effective?

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

I disagree, modifying the security group is risky!

Option B sounds like the best choice for security and cost.

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!

User 1: Option B sounds like the best solution. Setting up a bastion host with an EIP seems secure and cost-effective.

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

D) Bind an EIP to each of the ECS instances, and Jog on to each of these ECS instances to manage them.

B) Choose an ECS instance from VPC and make it as the bastion host And then, apply an EIP and bind it to this ECS instance. After that the administrator can manage other ECS instances through this bastion host.
