A media company wants to enhance its recommendation engine by incorporating third-party datasets into its analytics platform with minimal time and effort. Which option provides those datasets with the least operational overhead?

The correct option is to use API calls to access and integrate third-party datasets from AWS Data Exchange. AWS Data Exchange is a service that makes it easy to find, subscribe to, and use third-party data in the cloud. It provides a catalog of data products that can be accessed directly via API, minimizing operational overhead for data ingestion and integration. AWS DataSync is incorrect because it is a data transfer service designed for moving large amounts of data between on-premises storage and AWS storage services, or between different AWS storage services. It's not designed for integrating third-party datasets from external providers. Using Amazon Kinesis Data Streams with AWS CodeCommit or Amazon ECR is incorrect. Kinesis Data Streams is for real-time data streaming, and CodeCommit is a source control service for hosting Git repositories, while ECR is a fully managed Docker container registry. None of these services are designed for directly accessing and integrating third-party datasets from external providers in the way Data Exchange is.
