Question 443

A development team created and deployed a new AWS Lambda function 15 minutes ago. Although the function was invoked many times, Amazon CloudWatch Logs are not showing any log messages.

What is one cause of this?

The developers did not enable log messages for this Lambda function.

The Lambda function's role does not include permissions to create CloudWatch Logs items.

The Lambda function raises an exception before the first log statement has been reached.

The Lambda functions creates local log files that have to be shipped to CloudWatch Logs first before becoming visible.

Correct Answer: B

The most likely cause for the absence of log messages in Amazon CloudWatch Logs is that the Lambda function's role does not include permissions to create CloudWatch Logs items. Without the appropriate permissions, the Lambda function cannot generate or store logs in CloudWatch. This is a common issue when setting up new Lambda functions and their respective IAM roles.
