Topic 1 Question 102
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?

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

  A. Launch the EC2 instance into the same Availability Zone as the EFS file system. Makes sense to have the instance in the same AZ the EFS storage is. B. Install an AWS DataSync agent in the on-premises data center. The DataSync with move the data to the EFS, which already uses the EC2 instance (see the info provided). No more things are required... C. Create a secondary Amazon Elastic Block Store (Amazon EBS) volume on the EC2 instance for the data. This secondary EBS volume isn't required... the data should be move on to EFS... D. Manually use an operating system copy command to push the data to the EC2 instance. Potentially possible (instead of A), BUT the "automate this task" premise goes against any "manually" action. So, we should keep A. E. Use AWS DataSync to create a suitable location configuration for the on-premises SFTP server. I don't get the relationship between DataSync and the configuration for SFTP "on-prem"! Nonsense. So, anwers are A&B

  Answer and HOW-TO
  
  B. Install an AWS DataSync agent in the on-premises data center. E. Use AWS DataSync to create a suitable location configuration for the on-premises SFTP server.
  
  To automate the process of transferring the data from the on-premises SFTP server to an EC2 instance with an EFS file system, you can use AWS DataSync. AWS DataSync is a fully managed data transfer service that simplifies, automates, and accelerates transferring data between on-premises storage systems and Amazon S3, Amazon EFS, or Amazon FSx for Windows File Server.
  
  To use AWS DataSync for this task, you should first install an AWS DataSync agent in the on-premises data center. This agent is a lightweight software application that you install on your on-premises data source. The agent communicates with the AWS DataSync service to transfer data between the data source and target locations.

  I think E is a distractor. We need an instance(check the question) and datasync agent on prem. Hence A,B.
