Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon EC2 Windows instances with Amazon FSx for Windows File Server
Amazon EC2 Windows instances provide a native Windows environment, and Amazon FSx for Windows File Server offers fully managed Windows file shares that support SMB protocol, Windows authentication, and NTFS file system. This combination minimizes code changes by preserving the existing Windows authentication and local file system dependencies. Option A is incorrect because Amazon EFS uses NFS and does not natively support Windows SMB. Option B is incorrect because AWS Elastic Beanstalk for Windows may complicate Windows authentication and lacks the flexibility for direct file system access. Option C is incorrect because Amazon Lightsail with local instance storage does not provide shared file storage and may not scale as needed.
