Ultimate access to all questions.
A large education company has implemented Amazon Workspaces to facilitate access to internal applications across multiple universities. User profiles are stored on an Amazon FSx for Windows File Server, configured with a DNS alias and connected to a self-managed Active Directory. As the number of Workspace users grows, login times have become unacceptably long due to degraded file system performance. The initial file system was set up with HDD storage and a throughput of 16 MBps. To enhance performance during a scheduled maintenance window, a solutions architect needs to determine the most efficient solution with minimal administrative effort. What action should the solutions architect take?
A
Utilize AWS Backup to generate a point-in-time backup of the file system. Restore this backup to a new FSx for Windows File Server with SSD storage and a throughput capacity of 32 MBps. Once the restoration is complete, update the DNS alias and remove the original file system.
B
Temporarily disconnect users from the file system. Adjust the throughput capacity to 32 MBps and switch the storage type to SSD within the Amazon FSx console. After the changes, reconnect users to the file system.
C
Set up an AWS DataSync agent on a new Amazon EC2 instance. Create a DataSync task with the current file system as the source and a new FSx for Windows File Server with SSD storage and 32 MBps throughput as the destination. Schedule the task to execute during the maintenance window, then update the DNS alias and delete the original file system upon completion.
D
Initiate shadow copies on the existing file system using a Windows PowerShell command. Schedule a shadow copy job to create a point-in-time backup, enabling the restoration of previous versions. Establish a new FSx for Windows File Server with SSD storage and 32 MBps throughput. Adjust the DNS alias and delete the original file system after the shadow copy job is finished.
