Answer: Amazon FSx for Windows File Server

## Explanation Amazon FSx for Windows File Server is the correct choice because: - **Fully Managed**: Amazon FSx is a fully managed service that handles all the underlying infrastructure, patching, and maintenance - **Native Microsoft Support**: It's specifically designed for Windows file systems and Microsoft workloads - **SMB Protocol Support**: It natively supports the Server Message Block (SMB) protocol, which is essential for Windows file sharing - **Windows File Server Features**: Provides features like Active Directory integration, distributed file system (DFS), and Windows permissions ### Why not the other options: - **Amazon EFS**: Primarily designed for Linux workloads and uses NFS protocol, not SMB - **Amazon FSx for Lustre**: Optimized for high-performance computing and uses Lustre file system, not Windows file systems - **Amazon EBS**: Block storage service that requires you to manage the file system yourself, not a managed file server Amazon FSx for Windows File Server provides a fully managed Windows file server experience with native SMB protocol support, making it ideal for Microsoft workloads.
