AWS Certified Cloud Practitioner (CLF-C02) — Question 610

A company plans to perform a one-time migration of a large dataset with millions of files from its on-premises data center to the AWS Cloud.

Which AWS service should the company use for the migration?

Answer options

• A. AWS Database Migration Service (AWS DMS)
• B. AWS DataSync
• C. AWS Migration Hub
• D. AWS Application Migration Service

Correct answer: B

Explanation

AWS DataSync is designed specifically for simplifying, automating, and accelerating the transfer of massive datasets with millions of files between on-premises storage and AWS. In contrast, AWS DMS is used for database migrations, AWS Application Migration Service is intended for lift-and-shift server migrations, and AWS Migration Hub is a tracking tool rather than a data transfer service.
