A company is designing shared storage for a gaming application hosted in AWS. The storage must be accessible by SMB clients and be fully managed. Which AWS solution meets these requirements?

Amazon FSx for Windows File Server is a fully managed native Microsoft Windows file system, supporting the Server Message Block (SMB) protocol. This makes it ideal for Windows-based applications requiring shared file storage accessible via SMB, directly meeting the question's requirements for SMB client access and being fully managed. Incorrect options: AWS DataSync is a data transfer service, not a shared file system solution for applications. While it can move data, it doesn't provide a continuously mountable file system for application access in this context. Creating an Amazon EC2 Windows instance and configuring a Windows file share role would provide SMB access but is not a fully managed solution. The user would be responsible for patching, backups, and high availability of the EC2 instance. Amazon S3 is object storage, not a file system that supports SMB directly. While S3 buckets can be mounted using third-party tools, it's not a native file system and doesn't inherently support SMB for direct application access.
