A company is planning to run a number of Admin-related scripts using the AWS Lambda service. There is a need to understand if there are any errors encountered when the script runs. How can this be accomplished most effectively?

Answer options:

A.Use Cloudwatch metrics and logs to watch for errors.
B.Use Cloudtrail to monitor for errors.
C.Use the AWS Config service to monitor for errors.
D.Use the AWS Inspector service to monitor for errors.

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.
