Explanation

Amazon FSx File Gateway is the correct choice because:

• Hybrid Storage: FSx File Gateway provides a hybrid storage solution that connects on-premises environments to AWS Cloud storage
• Windows Compatibility: Amazon FSx is specifically designed for Windows file systems and supports SMB protocol, making it ideal for Windows users
• Low-Latency Performance: It caches frequently accessed data locally, providing low-latency access to hot data while storing less frequently accessed data in Amazon FSx in the cloud
• File Gateway Functionality: As a File Gateway, it presents file-based storage to on-premises applications through standard file protocols

Why other options are incorrect:

• Amazon EFS: Primarily for Linux-based file systems using NFS protocol, not optimized for Windows
• Amazon S3: Object storage service, not designed for low-latency file access or Windows file system integration
• Amazon EBS: Block storage service for EC2 instances, not designed for hybrid scenarios or file-level access across networks

Amazon FSx File Gateway combines the benefits of on-premises caching with cloud storage, making it perfect for Windows environments requiring hybrid storage with low-latency performance.
