Exam AWS Certified Solutions Architect - Professional topic 1 question 895 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional
Question #: 895
Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

A company is using Amazon WorkSpaces to provide access to its corporate applications across multiple global locations. User profile data is stored on an
Amazon FSx for Windows File Server file system that is configured with a DNS alias. The file system is linked to an existing Active Directory service.
Recently, the company added a new application that unexpectedly caused user profiles to grow significantly. The company increased the FSx for Windows File
Server file system size from 3 TiB to 6 TiB to prevent any issues. A few days later, the company made changes to the application's configuration. The user profile storage usage decreased significantly, leaving a large amount of free space on the file system. A solutions architect needs to reduce the size of the file system to avoid unnecessary costs.
What should the solutions architect do to achieve this goal?

  • A. During an agreed upon maintenance window, use AWS Backup to create a point-in-time backup of the file system. Restore the backup to a new, smaller FSx for Windows File Server file system. Adjust the DNS alias after the restore is completed. Delete the original file system.
  • B. During an agreed upon maintenance window, disconnect users from the file system. In the Amazon FSx console, update the storage capacity of the file system. Enter an absolute value of 3 TiB. Reconnect users to the file system.
  • C. Deploy an AWS DataSyne agent onto a new Amazon EC2 instance. Create a DataSync task. Configure the existing file system as the source location. Configure a new, smaller FSx for Windows File Server file system as the target location. Schedule the task. Adjust the DNS alias after the task is completed. Delete the original file system.
  • D. Enable shadow copies on the existing file system by using a Windows PowerShell command. Schedule a shadow copy job to create a point-in-time backup of the file system. Choose to restore previous versions, and create a new, smaller FSx for Windows File Server file system. Adjust the DNS alias after the copy job is completed. Delete the original file system.

Selected Answer: C
FSx – Solution Architecture Decrease FSx Volume Size • If you take a backup, you can only restore to a same size • You can only increase the amount of storage capacity for a file system; you cannot decrease storage capacity. • Instead, create a new FSx (smaller), use DataSync to sync data and then migrate your app over

Selected Answer: C
Can't restore to larger or smaller file system. Can't reduce file system size. C seems a bit convoluted but it's correct.

Q: Can I change my file system’s storage capacity and throughput capacity? A: Yes, you can increase the storage capacity, and increase or decrease the throughput capacity of your file system – while continuing to use it – at any time by clicking “Update storage" or "Update throughput” in the Amazon FSx Console, or by calling “update-file-system” in the AWS CLI/API and specifying the desired level.

It's not A, you can't restore to a smaller file system: Note You can only restore your backup to a file system of the same deployment type and storage capacity as the original. https://docs.aws.amazon.com/fsx/latest/WindowsGuide/using-backups.html#restoring-backups
