AWS Certified Cloud Practitioner — Question 873

Which AWS service monitors CPU utilization on Amazon EC2 instances?

Answer options

• A. AWS CloudTrail
• B. Amazon Inspector
• C. AWS Config
• D. Amazon CloudWatch

Correct answer: D

Explanation

Amazon CloudWatch is the primary monitoring and observability service in AWS, designed to collect and track metrics such as CPU utilization for Amazon EC2 instances. AWS CloudTrail is used for auditing API calls, AWS Config tracks resource configuration history, and Amazon Inspector is a security assessment service, making them incorrect for performance monitoring.
