A company needs to mount a file share across multiple Amazon EC2 instances as a mapped drive by using the SMB protocol. Which AWS service will meet these requirements?
A
Amazon FSx for Windows File Server
B
Amazon Elastic File System (Amazon EFS)
C
Amazon S3
D
AWS DataSync
Explanation:
Amazon FSx for Windows File Server is the correct choice because:
SMB Protocol Support: FSx for Windows File Server natively supports the Server Message Block (SMB) protocol, which is required for mounting file shares as mapped drives on Windows systems
Multi-instance Access: Multiple EC2 instances can simultaneously access the same file share
Windows Integration: Designed specifically for Windows environments and integrates seamlessly with Active Directory
Mapped Drive Compatibility: Perfectly suited for the mapped drive requirement
Why other options are incorrect:
Amazon EFS: Uses NFS protocol, not SMB protocol
Amazon S3: Object storage service, not designed for file share mounting as mapped drives
AWS DataSync: Data transfer service, not a file sharing service
The requirement specifically calls for SMB protocol support and mapped drive functionality, which makes FSx for Windows File Server the ideal solution.
