A. B. C. D.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.
Options B, C and D are all invalid because these services cannot be used to monitor for errors.

https://docs.aws.amazon.com/lambda/latest/dg/monitoring-functions-logs.htmlThe most effective way to monitor for errors in AWS Lambda scripts is by using CloudWatch Metrics and Logs. CloudWatch provides monitoring and observability services for resources and applications running in AWS. By default, AWS Lambda automatically logs the output of your function invocations to CloudWatch Logs, and you can add additional logging statements to your code to capture specific information.
To monitor for errors, you can create a CloudWatch metric filter that looks for specific error messages or patterns in the logs. The filter can then trigger an alarm that alerts you or your team when an error occurs. Additionally, you can use CloudWatch Logs Insights to search and analyze your logs to find errors or other issues.
CloudTrail is not the best option for monitoring errors in AWS Lambda scripts because it primarily logs API calls and events within your AWS account. While you can use CloudTrail to track Lambda function invocations, it may not provide the level of detail needed to identify specific errors or issues.
AWS Config is a service that enables you to assess, audit, and evaluate the configuration of your AWS resources. It is not designed to monitor runtime errors or issues with Lambda functions.
AWS Inspector is a security assessment service that helps you identify security vulnerabilities and compliance issues in your AWS resources. While it can help identify issues related to security and compliance, it is not designed to monitor for errors in Lambda functions.
Therefore, the correct answer to this question is A: Use CloudWatch metrics and logs to watch for errors.
