Explanation

Explanation

Amazon EC2 is the correct answer because AWS Compute Optimizer analyzes CloudWatch utilization metrics from EC2 instances and Auto Scaling groups to deliver machine learning-based recommendations for optimal instance types and sizes, helping reduce costs and improve performance.

Amazon RDS (B) has its own built-in recommendations through the RDS console and Performance Insights, but it is not integrated with AWS Compute Optimizer - Optimizer focuses on compute resources, not managed databases.

Amazon Lightsail (C) is a simplified, fixed-bundle service for smaller workloads and does not integrate with Compute Optimizer, as it abstracts away the granular resource configuration that Optimizer requires.

AWS Step Functions (D) is a serverless workflow orchestration service that has no relevance to compute sizing recommendations, as it coordinates tasks rather than managing underlying compute resources.

Memory Tip

Think of "Compute" Optimizer = EC2 (Compute)" - the word Compute in the service name is your direct clue. Compute Optimizer was purpose-built to right-size compute instances (EC2, Lambda, and EBS), not databases or workflow tools.
