AWS Certified Cloud Practitioner (CLF-C02) — Question 463

A systems administrator wants to monitor the CPU utilization of a company's Amazon EC2 instances.

Which AWS service can provide this information?

Answer options

• A. AWS Config
• B. AWS Trusted Advisor
• C. AWS CloudTrail
• D. Amazon CloudWatch

Correct answer: D

Explanation

Amazon CloudWatch is the primary monitoring and observability service in AWS that collects and tracks performance metrics, including CPU utilization, for Amazon EC2 instances. AWS Config is used for resource configuration history, AWS CloudTrail tracks API activity and user actions, and AWS Trusted Advisor offers optimization recommendations, meaning none of these three monitor real-time resource performance metrics.
