A company needs fully managed, highly reliable, and scalable file storage that is accessible over the Server Message Block (SMB) protocol. Which AWS service will meet these requirements?
A
Amazon S3
B
Amazon Elastic File System (Amazon EFS)
C
Amazon FSx for Windows File Server
D
Amazon Elastic Block Store (Amazon EBS)
Explanation:
Amazon FSx for Windows File Server is the correct choice because:
Fully managed: AWS handles all the administrative tasks including hardware provisioning, software configuration, patching, and backups
Highly reliable: Provides built-in redundancy and automatic failover capabilities
Scalable: Can scale storage capacity and performance independently
SMB protocol support: Specifically designed to support the Server Message Block (SMB) protocol, which is the standard file sharing protocol for Windows environments
Why the other options are incorrect:
Amazon S3: Object storage service, not file storage; uses REST APIs, not SMB protocol
Amazon EFS: File storage service but uses NFS protocol (Network File System), not SMB protocol
Amazon EBS: Block storage service for use with EC2 instances, not a standalone file storage service accessible over SMB
Amazon FSx for Windows File Server is specifically optimized for Windows-based applications and provides native Windows file system features, making it the ideal choice for SMB protocol requirements.
