You’ve just created an AWS Lambda function. You’re running the function, but the output of the function is not as expected. You need to check and see what the issue is. Which of the following can help the developer debug the issue with the Lambda function?

Answer options:

A.Check Cloudwatch logs
B.Check VPC Flow Logs
C.Check AWS Trusted Advisor
D.Check AWS Inspector

Answer – A
The AWS Documentation mentions the following.
AWS Lambda automatically monitors Lambda functions on your behalf, reporting metrics through Amazon CloudWatch. To help you troubleshoot failures in a function, Lambda logs all requests handled by your function and automatically stores logs generated by your code through Amazon CloudWatch Logs.
Option B is incorrect because VPC Flow Logs is a feature that enables you to capture information about the IP traffic going to and from network interfaces in your VPC.Option C is incorrect because AWS Trusted Advisor is an online tool that provides you real-time guidance to help you provision your resources following AWS best practices. It cannot be used to debug Lambda functions.
Option D is incorrect because Amazon Inspector is an automated security assessment service that helps improve the security and compliance of applications deployed on AWS. It is not a troubleshooting tool for the Lambda function.
