AWS Certified Solutions Architect – Professional — Question 509

You set up your first Lambda function and want to set up some Cloudwatch metrics to monitor your function. Which of the following Lambda metrics can
Cloudwatch monitor?

Answer options

• A. Total requests only
• B. Status Check Failed, total requests, and error rates
• C. Total requests and CPU utilization
• D. Total invocations, errors, duration, and throttles

Correct answer: D

Explanation

AWS Lambda automatically sends standard performance metrics to Amazon CloudWatch, including Invocations, Errors, Duration, and Throttles. It does not provide host-level metrics like CPU utilization or EC2-specific metrics like Status Check Failed, making option D the only correct choice.
