Explanation

AWS DataSync provides a fully managed, secure, and high-performance service for transferring large amounts of data between on-premises storage and Amazon S3. It uses TLS encryption in transit and automates data validation, scheduling, and monitoring. "AWS DataSync securely and efficiently transfers large amounts of data online between on- premises storage and AWS services. All data is encrypted in transit using TLS." Why B is correct: Encrypts all data in transit automatically. Optimized for high-throughput WAN environments (100 Mbps to multi-Gbps). Fully managed, with no need to provision additional infrastructure. Integrates natively with S3 and supports incremental syncs. Why others are incorrect: A: DMS is designed for database migration, not unstructured data. C: Snowball is for offline migrations, not needed given available connectivity. D: Direct Connect is costly for temporary data transfers and unnecessary here.
