A company wants to migrate an on-premises data center to AWS. The data center hosts an SFTP server that stores its data on an NFS-based file system. The server holds 200 GB of data that needs to be transferred. The server must be hosted on an Amazon EC2 instance that uses an Amazon Elastic File System (Amazon EFS) file system.
Which combination of steps should a solutions architect take to automate this task? (Choose two.)

UAnonymous
A
Launch the EC2 instance into the same Availability Zone as the EFS file system.
B
Install an AWS DataSync agent in the on-premises data center.
C
Create a secondary Amazon Elastic Block Store (Amazon EBS) volume on the EC2 instance for the data.
D
Manually use an operating system copy command to push the data to the EC2 instance.
E
Use AWS DataSync to create a suitable location configuration for the on-premises SFTP server.

Explanation
Correct Answers: B and E
B. Install an AWS DataSync agent in the on-premises data center. - AWS DataSync is designed for automated data transfer between on-premises storage systems and AWS storage services. To use DataSync with on-premises systems, you need to install a DataSync agent in your data center.
E. Use AWS DataSync to create a suitable location configuration for the on-premises SFTP server. - After installing the agent, you need to configure DataSync to recognize your on-premises SFTP server as a source location and your EFS file system as a destination location.
Why other options are incorrect:
A. Launch the EC2 instance into the same Availability Zone as the EFS file system. - While this is a good practice for performance (EFS mounts are faster within the same AZ), it's not specifically required for automating the data migration task. The question focuses on automating the data transfer, not optimizing performance.
C. Create a secondary Amazon Elastic Block Store (Amazon EBS) volume on the EC2 instance for the data. - This is unnecessary since the requirement specifies using EFS, not EBS. EFS is a managed NFS file system that can be mounted to multiple EC2 instances, while EBS is block storage attached to a single instance.
D. Manually use an operating system copy command to push the data to the EC2 instance. - This contradicts the requirement to "automate this task." Manual copying is not automated and would be inefficient for 200 GB of data.
Key Points:
- AWS DataSync is the recommended service for automated, secure data transfer between on-premises and AWS
- DataSync agents must be installed on-premises to access local file systems
- DataSync supports NFS-based file systems (which the SFTP server uses)
- The automation aspect eliminates manual copying and ensures reliable, scheduled data transfers
