Which AWS service uses AWS Compute Optimizer to provide sizing recommendations based on workload metrics?

Answer options

• A. Amazon EC2
• B. Amazon RDS
• C. Amazon Lightsail

Correct answer: A

Explanation

AWS Compute Optimizer analyzes historical utilization metrics to provide optimal configuration recommendations for Amazon EC2 instances, EBS volumes, and Lambda functions.
