AWS Certified Cloud Practitioner Practice Exam

AWS Step Functions is the correct answer because it is the only service listed that specifically allows you to create serverless workflows. Option B, AWS Batch, is incorrect because it is primarily used for batch computing, not serverless workflows. Option C, Amazon SWF, is incorrect because it is an older service that has since been replaced by AWS Step Functions for workflow orchestration. Option D, AWS CodePipeline, is incorrect because it is a continuous delivery service and does not support serverless workflows.
