SAA-C03 Question #591: Real Exam Question with Answer & Explanation
The correct answer is C: Configure AWS Compute Optimizer for cost recommendations for the EC2 instances, the Auto. A company needs to identify cost optimizations across Amazon EC2 instances, their Auto Scaling group, and Amazon EBS volumes for an internal application, aiming for the most operational efficiency.
Question
A company has an internal application that runs on Amazon EC2 instances in an Auto Scaling group. The EC2 instances are compute optimized and use Amazon Elastic Block Store (Amazon EBS) volumes. The company wants to identify cost optimizations across the EC2 instances, the Auto Scaling group, and the EBS volumes. Which solution will meet these requirements with the MOST operational efficiency?
Options
- ACreate a new AWS Cost and Usage Report. Search the report for cost recommendations for the
- BCreate new Amazon CloudWatch billing alerts. Check the alert statuses for cost
- CConfigure AWS Compute Optimizer for cost recommendations for the EC2 instances, the Auto

Explanation

Common mistakes.
- A. While AWS Cost and Usage Reports (CUR) contain detailed billing data, extracting specific cost optimization recommendations for right-sizing EC2 instances, ASGs, and EBS volumes from CURs requires extensive manual analysis and expertise, making it less operationally efficient than an automated service like Compute Optimizer.
- B. Amazon CloudWatch billing alerts are designed to notify users when their AWS costs exceed predefined thresholds. They do not provide specific recommendations for optimizing resource configurations (EC2, ASG, EBS) to reduce costs; they only monitor for budget breaches.
- D. Configuring AWS Compute Optimizer only for EC2 instances is an incomplete solution, as the requirement specifies optimizations across EC2, the Auto Scaling group, and EBS volumes. Creating a separate Cost and Usage Report for EBS volumes would be less operationally efficient than using Compute Optimizer's integrated recommendations for all relevant resource types.
