PAS-C01 Design of SAP Workloads on AWS Practice Question
A customer is running SAP NetWeaver on AWS and wants to use Amazon EFS for shared file storage for the SAP transport directory. Which access option should be used to secure the file system?
⚠ Common exam trap
Many candidates confuse network-level access controls (security groups) with identity-based controls (IAM roles) or assume that EFS, being a shared file system, can be secured with policies similar to S3 bucket policies.

Correct answer & explanation
✓
Security group
Amazon EFS uses security groups as a stateful firewall to control NFS traffic (port 2049) at the network level. For SAP transport directories, security groups allow you to restrict access to specific EC2 instances or other AWS resources that need to mount the EFS file system, providing granular network-layer security without managing individual IP addresses.
