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:
SMB Protocol Support: Amazon FSx for Windows File Server is specifically designed to provide fully managed Windows file servers that support the Server Message Block (SMB) protocol, which is the standard file sharing protocol for Windows environments.
Fully Managed: AWS manages the underlying infrastructure, including hardware provisioning, software configuration, patching, and backups, making it a fully managed service.
Highly Reliable: It provides high availability through Multi-AZ deployments and automatic failover capabilities.
Scalable: It offers scalable storage capacity and performance that can grow with your needs.
Why the other options are incorrect:
Amazon S3: While highly scalable and reliable, S3 is an object storage service that doesn't support SMB protocol natively. It's designed for storing and retrieving objects, not for file system access via SMB.
Amazon Elastic File System (Amazon EFS): This is a fully managed NFS (Network File System) service, not SMB. It's designed for Linux-based workloads and uses the NFS protocol.
Amazon Elastic Block Store (Amazon EBS): This is block-level storage for EC2 instances, not a file storage service accessible over SMB. EBS volumes need to be attached to EC2 instances and formatted with a file system.
Key Takeaway: When you need Windows-compatible file storage with SMB protocol support in AWS, Amazon FSx for Windows File Server is the appropriate choice.
