[All AWS Certified Developer - Associate DVA-C02 Questions]

A company has an analytics application that uses an AWS Lambda function to process transaction data asynchronously. A developer notices that asynchronous invocations of the Lambda function sometimes fail. When failed Lambda function invocations occur, the developer wants to invoke a second Lambda function to handle errors and log details.

Which solution will meet these requirements?

A. Configure a Lambda function destination with a failure condition. Specify Lambda function as the destination type. Specify the error-handling Lambda function's Amazon Resource Name (ARN) as the resource.
B. Enable AWS X-Ray active tracing on the initial Lambda function. Configure X-Ray to capture stack traces of the failed invocations. Invoke the error-handling Lambda function by including the stack traces in the event object.
C. Configure a Lambda function trigger with a failure condition. Specify Lambda function as the destination type. Specify the error-handling Lambda function's Amazon Resource Name (ARN) as the resource.
D. Create a status check alarm on the initial Lambda function. Configure the alarm to invoke the error-handling Lambda function when the alarm is initiated. Ensure that the alarm passes the stack trace in the event object.

Lambda destinations allow you to configure what happens to Lambda function invocation records when an invocation is successful or, in this case, when it fails. By setting a destination for failed invocations, you can specify another Lambda function to handle errors. This setup enables automatic error handling without requiring changes to the application code or the use of additional services for monitoring and triggering error-handling mechanisms. The error-handling Lambda function can then log details, send notifications, or take corrective actions as needed.

Should be A since Trigger is before execution

Selected Answer: A

is not a valid approach because Lambda does not have a direct configuration for triggers based on failure conditions in the way described. The concept of a trigger is generally used for starting an invocation, not handling failures.
