A company has recently started using AWS Cloud services and needs to transfer a large set of data online from on-prem Windows servers to AWS Storage Services S3, EFS, and FSx. This transfer should be a bi-directional, reliable, and incremental based on schedules.
How would a Solution Architect design this solution? 

Answer options:

A.Use Snowball devices to transfer data to S3, EFS and FSx.
B.Use AWS DataSync service to transfer data to AWS Services.
C.AWS Database Migration Service to transfer data to AWS services.
D.Use AWS S3 Transfer acceleration to transfer a large set of data.

Answer: B
Option A is incorrect because snowball devices are used to transfer a large set of data electronically but do not meet the bi-directional and incremental transfer requirements.
Option B is CORRECT because it is a more reliable service to transfer data bi-directionally, supporting S3, EFS and FSx. DataSync helps to move data over the network between on-premise File Systems storage and AWS Storage services. DataSync automates both the management of data transfer processes and the infrastructure required for high-performance, secure data transfer.
Option C is incorrect because the Data migration service is used to transfer databases to AWS RDS.
Option D is incorrect because S3 Transfer acceleration is used to accelerate data transfer to S3 and doesn’t support bi-directional and the fie systems.
