Question 19 of 65 | ← Chapter 5

Q319. A company recently created a disaster recovery site in a different AWS Region.The company needs to transfer large amounts of data back and forth between NFS file systems in the two Regions on a periodic basis.Which solution will meet these requirements with the LEAST operational overhead?

Correct Answer: A. Use AWS DataSync

Explanation

AWS DataSync is a fully managed, simple and fast service that makes it easy to move large amounts of data between NFS file systems. It reduces the time taken to transfer files over the network by using a purpose-built protocol and automatically parallelizes transfers over multiple threads. DataSync can replicate data from one NFS server to another, both of which can be located inside or outside of an Amazon VPC, making it ideal for use cases such as disaster recovery.Option B, using AWS Snowball devices, may require more operational overhead as it involves physically shipping the storage devices back and forth between regions. Option C, setting up an SFTP server on Amazon EC2, would require configuring and managing the server infrastructure, security, and scalability, which can lead to increased operational overhead. Option D, using AWS Database Migration Service (DMS), is not suitable for transferring large amounts of data between NFS file systems, as it is primarily designed for database migration and replication.
