Selected Answer: B

For what it's worth, since the app servers are installed in three different AZ's, you could drop an app server in one AZ and meet the HA requirement. However, this does make some presumptions on the utilization. However, I do believe B is probably the right answer (from researching AWS documentation) "The rightsizing recommendations feature in Cost Explorer helps you identify cost-saving opportunities by downsizing or terminating instances in Amazon Elastic Compute Cloud (Amazon EC2). Rightsizing recommendations analyze your Amazon EC2 resources and usage to show opportunities for how you can lower your spending. You can see all of your underutilized Amazon EC2 instances across member accounts in a single view to immediately identify how much you can save. After you identify your recommendations, you can take action on the Amazon EC2 console." https://docs.aws.amazon.com/cost-management/latest/userguide/ce-rightsizing.html

B for sure. You can't reduce the number of instances.

Well... For me it's is certainly not: C -> LoadBalancing will not reduce your cost in the end D -> Increasing the size of your servers is pretty much obvious why is not a good idea That leaves A or B. I believe it is not A because the use case tells us to NOT mess with the application's "high availability and design". That means that the application should still be running on a 3-server configuration across 3 availability zones as that ensures HA and might have special design considerations in its programming. So that leaves us with B and trusting the AWS Cost Explorer and its right sizing.
