Exam question from Amazon's AWS Certified Solutions Architect - Professional
Question #: 802
Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

A company's site reliability engineer is performing a review of Amazon FSx for Windows File Server deployments within an account that the company acquired.
Company policy states that all Amazon FSx file systems must be configured to be highly available across Availability Zones.
During the review, the site reliability engineer discovers that one of the Amazon FSx file systems used a deployment type of Single-AZ 2. A solutions architect needs to minimize downtime while aligning this Amazon FSx file system with company policy.
What should the solutions architect do to meet these requirements?

  • A. Reconfigure the deployment type to Multi-AZ for this Amazon FSx file system.
  • B. Create a new Amazon FSx file system with a deployment type of Multi-AZ. Use AWS DataSync to transfer data to the new Amazon FSx file system. Point users to the new location.
  • C. Create a second Amazon FSx file system with a deployment type of Single-AZ 2. Use AWS DataSync to keep the data in sync. Switch users to the second Amazon FSx file system in the event of failure.
  • D. Use the AWS Management Console to take a backup of the Amazon FSx file system. Create a new Amazon FSx file system with a deployment type of Multi- AZ. Restore the backup to the new Amazon FSx file system. Point users to the new location.

Correct D. Data sync is not needed when the Amazon FSx file system is set up as Multi-AZ, because data is replicated synchronously within each individual AZ and between the two AZs.

Selected Answer: B
B. We recommend using AWS DataSync to transfer data between FSx for Windows File Server file systems. DataSync is a data transfer service that simplifies, automates, and accelerates moving and replicating data between on-premises storage systems and other AWS storage services over the internet or AWS Direct Connect. DataSync can transfer your file system data and metadata, such as ownership, timestamps, and access permissions.

Selected Answer: B
Only B and D are valid - according to AWS documentation the correct way is to use DataSync to sync the two FSx once done - switch to the new one. So B is the most correct one

Obviously it's between B and D. D implies risk of loosing data which was uploaded or changed since the snapshot was taken. So I'm going with B.

B should be right answer - refer FAQ for usage of Data Sync. If you’d like to migrate your existing files to Amazon FSx for Windows File Server file systems, we recommend the use of AWS DataSync, an online data transfer service designed to simplify, automate, and accelerate copying large amounts of data to and from AWS storage services.
