Question 4

A solutions architect is designing a migration strategy for a company moving to the AWS Cloud. The company uses a shared Microsoft file system that uses Distributed File System Namespaces (DFSN). What will be the most suitable migration strategy for the file system?

  1. Use the AWS Server Migration Service to migrate to an Amazon S3 bucket.
  2. Use the AWS Server Migration Service to migrate to Amazon FSx for Lustre.
  3. Use AWS DataSync to migrate to an Amazon EFS file system.
  4. Use AWS DataSync to migrate to Amazon FSx for Windows File Server.

Correct Answer: 4

Explanation: The destination file system should be Amazon FSx for Windows File Server. This supports DFSN and is the most suitable storage solution for Microsoft file systems. AWS DataSync supports migrating to the Amazon FSx and automates the process.

INCORRECT: “Use the AWS Server Migration Service to migrate to an Amazon S3 bucket.” is incorrect. The server migration service is used to migrate virtual machines, and Amazon S3 is an object-based storage system and unsuitable for hosting a Microsoft file system.

INCORRECT: “Use the AWS Server Migration Service to migrate to Amazon FSx for Lustre.” is incorrect. The server migration service is used to migrate virtual machines, and FSx for Lustre does not support Windows file systems.

INCORRECT: “Use AWS DataSync to migrate to an Amazon EFS file system.” is incorrect. You can migrate data to EFS using DataSync, but it is the wrong destination for a Microsoft file system (Linux only).

CORRECT: “Use AWS DataSync to migrate to Amazon FSx for Windows File Server.” is the correct answer.
