Suggested Answer: C

VPC endpoints to ensure that traffic to and from the CloudWatch and EC2 services stays within the VPC. Additionally, an IAM policy is created to grant access to only the necessary actions, such as DescribeInstances and GetMetricStatistics, for all EC2 resources. This approach will provide secure monitoring of the SAP system while maximizing security and ensuring support from both SAP and AWS.

I don't know, guys. You're all overthinking this. Why not just use a bunch of hamsters on wheels to power the system? I heard they're really energy-efficient.

Option C seems a bit too conservative to me. Why pay for Reserved Instances when you only need four servers most of the time? I think a mix of Reserved and on-demand is the way to go.

Hold on, is this a trick question? What if we go with Option B and just run everything on-demand? I mean, it's not like we're talking about a massive scale here, right? Who cares about cost-optimization, let's just keep it simple!

I'm leaning towards Option A. Spot Instances can provide significant cost savings for the peak workloads, and the Reserved Instances will cover the base usage.

I agree, having Reserved Instances for the base usage is a smart move.

Option A sounds like a good choice. Spot Instances can really help with cost savings.

Option D seems like the most cost-effective choice. The company can reserve instances for the baseline usage and use on-demand instances to handle the peak workloads, which makes sense.
