AWS Certified Solutions Architect – Associate (SAA-C02) — Question 686

A company has a large Microsoft SharePoint deployment running on-premises that requires Microsoft Windows shared file storage. The company wants to migrate this workload to the AWS Cloud and is considering various storage options. The storage solution must be highly available and integrated with Active
Directory for access control.
Which solution will satisfy these requirements?

Answer options

• A. Configure Amazon EFS Amazon Elastic File System (Amazon EFS) storage and set the Active Directory domain for authentication.
• B. Create an SMB file share on an AWS Storage Gateway file gateway in two Availability Zones.
• C. Create an Amazon S3 bucket and configure Microsoft Windows Server to mount it as a volume.
• D. Create an Amazon FSx for Windows File Server file system on AWS and set the Active Directory domain for authentication.

Correct answer: D

Explanation

Amazon FSx for Windows File Server is the ideal solution because it is a fully managed, highly available Windows file system that natively supports the SMB protocol and integrates seamlessly with Active Directory for access control. Amazon EFS is designed for Linux workloads and uses NFS, which does not support Windows Active Directory natively. AWS Storage Gateway and Amazon S3 are not recommended or native solutions for hosting the highly available, active-active shared storage required directly by Microsoft SharePoint.
