AWS Certified Cloud Practitioner — Question 499

A company recently migrated to the AWS Cloud. The company needs to determine whether its newly imported Amazon EC2 instances are the appropriate size and type.

Which AWS services can provide this information to the company? (Choose two.)

Answer options

• A. AWS Auto Scaling
• B. AWS Control Tower
• C. AWS Trusted Advisor
• D. AWS Compute Optimizer
• E. Amazon Forecast

Correct answer: C, D

Explanation

AWS Compute Optimizer analyzes resource configurations and utilization metrics to recommend optimal AWS resources, specifically identifying if EC2 instances are over- or under-provisioned. AWS Trusted Advisor also provides cost optimization checks, including identifying underutilized EC2 instances to help size them appropriately. Other options like AWS Auto Scaling, AWS Control Tower, and Amazon Forecast do not analyze and recommend appropriate EC2 instance sizing.
