AWS Certified Solutions Architect – Associate (SAA-C02) — Question 498

A company wants to perform an online migration of active datasets from an on-premises NFS server to an Amazon S3 bucket that is named DOC-EXAMPLE-
BUCKET. Data integrity verification is required during the transfer and at the end of the transfer. The data also must be encrypted.
A solutions architect is using an AWS solution to migrate the data.
Which solution meets these requirements?

Answer options

Correct answer: C

Explanation

AWS DataSync is the ideal service for online data transfers from on-premises NFS systems to Amazon S3, as it natively supports end-to-end data integrity verification and encryption during transit. AWS Storage Gateway is designed for hybrid cloud storage rather than dedicated migrations, and Amazon S3 Transfer Acceleration only optimizes transfer speeds over long distances. AWS Snowball Edge is an offline data transfer mechanism, which does not meet the online migration requirement.
