AWS Certified Cloud Practitioner — Question 644

Which AWS service is designed to help users orchestrate a workflow process for a set of AWS Lambda functions?

Answer options

• A. Amazon DynamoDB
• B. AWS CodePipeline
• C. AWS Batch
• D. AWS Step Functions

Correct answer: D

Explanation

AWS Step Functions is a serverless orchestration service that enables you to coordinate multiple AWS services, such as AWS Lambda, into visual workflows. Amazon DynamoDB is a NoSQL database, AWS CodePipeline is a continuous delivery service, and AWS Batch is designed for containerized batch workloads, making them unsuitable for orchestrating Lambda workflows.
