A. The Lambda function does not have any explicit log statements for the log data to send it to CloudWatch Logs. -- If lambda was executed, it will always have some logs to send. For example execution time and memory usage will be always send after execution is done. [Incorrect] B. The Lambda function is missing CloudWatch Logs as a source trigger to send log data. -- Lambda is connected to CloudWatch by default and you cannot disable it. [Incorrect] C. The execution role for the Lambda function is missing permissions to write log data to the CloudWatch Logs. -- You have to explicitly define a IAM role with IAM policy which allows Lambda to send logs to CloudWatch. [Correct] D. The Lambda function is missing a target CloudWatch Log group. -- See explanation in answer B. [Incorrect]
