Example question from this domain

A Step Functions workflow must transform a state's input before a task runs and keep only selected fields from the task result. Which fields support this data-shaping behavior?

  • InputPath, ResultPath, and OutputPath.
  • PartitionKey, SortKey, and TableName.
  • QueueUrl, ReceiptHandle, and DelaySeconds.
  • Bucket, Key, and ContentType.

InputPath, ResultPath, and OutputPath. — InputPath, ResultPath, and OutputPath control how Step Functions selects input, stores task results, and shapes output.

PartitionKey, SortKey, and TableName. — These are DynamoDB table and key concepts, not Step Functions state data transformation fields.

QueueUrl, ReceiptHandle, and DelaySeconds. — These are SQS message operation fields and do not shape Step Functions state input and output.

Bucket, Key, and ContentType. — These are S3 object fields and are not used for Step Functions data path handling.
