A is correct.

{ "Type": "Task", "Resource": "arn:aws:lambda:region:account-id:function:function-name", "Retry": [ { "ErrorEquals": ["States.Timeout"], "IntervalSeconds": 2, "MaxAttempts": 3, "BackoffRate": 2.0 } ], "End": true }

A is the correct answer.

AWS Step Functions allows you to handle errors and automate retry policies directly within your state machine definition. By adding a Retry field to the state definition of the Lambda function within the Step Functions state machine, you can specify the error types for which retries should occur, including timeout errors. You can also configure the maximum number of retry attempts, the interval between retries, backoff rate, and more. This solution directly addresses the need for automatic retry in case of specific errors such as timeouts, making it an efficient way to enhance the resilience of serverless workflows.
