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 FSx for Windows File Server
Mazon FSx for Windows File Server (option C). This service provides a fully managed native Windows file system that is accessible from multiple EC2 instances in the same VPC, supporting the SMB protocol required by Windows applications. Option A (Amazon EBS) is block storage that can be attached to only one instance at a time, not a shared file system. Option B (Amazon S3) is object storage and does not provide a file system interface. Option D (AWS Storage Gateway) is used for hybrid cloud storage and is not the optimal choice for this scenario.
