AWS Certified Solutions Architect – Associate (SAA-C02) — Question 420

A company is migrating its applications to AWS. Currently, applications that run on premises generate hundreds of terabytes of data that is stored on a shared file system. The company is running an analytics application in the cloud that runs hourly to generate insights from this data.
The company needs a solution to handle the ongoing data transfer between the on-premises shared file system and Amazon S3. The solution also must be able to handle occasional interruptions in internet connectivity.
Which solutions should the company use for the data transfer to meet these requirements?

Answer options

Correct answer: A

Explanation

AWS DataSync is the ideal service for automating and accelerating continuous data transfers between on-premises storage systems and Amazon S3, as it inherently manages network interruptions by retrying transfers and verifying data integrity. AWS Snowball Edge is designed for offline, one-time physical data migrations rather than ongoing hourly synchronization. AWS Migration Hub is used to monitor migration progress, and AWS Transfer for SFTP is for managing SFTP/FTPS/FTP transfers rather than automated file system syncing.
