PAS-C01 Technology Practice Question
A company runs SAP on AWS and uses a shared file system for SAP transport files. The system must support concurrent access from multiple SAP application servers and provide strong consistency. The transport files are typically small (less than 1 MB) and are frequently read and written. Which file storage solution should be used?
⚠ Common exam trap
Candidates often confuse object storage (S3) with file storage, or assume that any shared storage (like FSx for Windows) works for Linux-based SAP workloads, overlooking the specific POSIX and consistency requirements of SAP transport files.

Correct answer & explanation
✓
Amazon EFS
Amazon EFS (Elastic File System) provides a fully managed, POSIX-compliant, shared file system that supports concurrent access from multiple EC2 instances (SAP application servers) with strong consistency. It uses the NFSv4.1 protocol, which ensures that read-after-write consistency is maintained across all clients, making it ideal for SAP transport files that are frequently read and written.
