A company needs to transfer unstructured data to AWS with encryption in transit and end-to-end data validation. Which AWS service meets these requirements?

AWS DataSync is the correct choice because it is a data transfer service that simplifies, automates, and accelerates moving data between on-premises storage systems and AWS storage services, or between AWS storage services. It inherently provides encryption in transit and end-to-end data validation to ensure data integrity during transfers. AWS Application Migration Service (AWS MGN) is primarily for migrating applications and servers to AWS, not specifically for unstructured data transfer with validation. Amazon EFS is a scalable, elastic, cloud-native NFS file system for EC2 instances, not a data transfer service for moving data into AWS. AWS Migration Hub provides a single location to track the progress of application migrations across multiple AWS and partner solutions, but it does not perform the actual data transfer or validation.
