Which EC2 instance purchasing option meets these requirements MOST cost-effectively?
A. Dedicated Instances
B. Spot Instances
C. Reserved Instances
D. On-Demand Instances
Show Answer

The Developer Support plan only includes a limited subset of Trusted Advisor checks, and AWS Health Dashboard does not provide these best-practice recommendations.
