Question #1023
A company needs to migrate on-premises backup files to AWS. The migration requires encrypted data transfer and end-to-end integrity verification to ensure data consistency. Which AWS service should be used?
AWS Application Migration Service
Amazon Elastic File System (Amazon EFS)
AWS DataSync
AWS Migration Hub
Explanation
AWS DataSync is designed for secure and efficient data transfer between on-premises storage and AWS services (e.g., Amazon S3, EFS). It automatically encrypts data in transit using TLS and validates data integrity with checksums, ensuring end-to-end consistency.
Why other options are incorrect:
- A. AWS Application Migration Service: Focuses on migrating applications/servers (lift-and-shift), not bulk file transfers.
- B. Amazon EFS: A storage service, not a migration tool; it does not handle data transfer or encryption during migration.
- D. AWS Migration Hub: A tracking/monitoring tool for migrations, not a data transfer service.
Key Points:
- DataSync ensures encryption (TLS) and integrity checks (checksums) during transfers.
- Use DataSync for large-scale, secure file migrations to AWS storage services.
Answer
The correct answer is: C
