Which AWS service should they configure as the target for failed processing events?
Configure an Amazon Simple Notification Service (SNS) topic as a dead-letter queue for the Lambda function.
Direct the Lambda function to write all failed event messages to a designated Amazon S3 bucket.
Set up Amazon CloudWatch to capture logs for failed Lambda invocations.
Configure an Amazon Simple Queue Service (SQS) queue as a dead-letter queue for the Lambda function.
