PAS-C01 Technology Practice Question
A company is migrating an SAP ERP system to AWS and needs to ensure high availability for the SAP Central Services (ASCS) and Enqueue Replication Server (ERS). The solution must use a shared file system for the SAP transport directory. Which combination of AWS services should be used?
⚠ Common exam trap
Watch out — candidates often assume a shared file system must be block storage (like EBS) or Windows-based (like FSx), but they overlook that SAP on Linux requires NFS-based shared storage, and Amazon EFS is the native AWS NFS solution that supports multi-AZ access and high availability.

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 EFS for the transport directory and two EC2 instances with a floating IP
SAP ASCS and ERS require a highly available shared file system for the SAP transport directory, and Amazon EFS provides a fully managed NFS file system that can be mounted by multiple EC2 instances across Availability Zones. The floating IP (using AWS Elastic IP or a secondary private IP) allows the ASCS and ERS services to fail over transparently between the two EC2 instances, meeting the high availability requirements without relying on a single point of failure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon FSx for Windows File Server for the transport directory
Why it's wrong here
FSx for Windows is not suitable for Linux-based SAP systems.
- ✗
Amazon S3 as the transport directory with two application servers
Why it's wrong here
S3 does not support POSIX file locking required by SAP transport.
- ✓
Amazon EFS for the transport directory and two EC2 instances with a floating IP
Why this is correct
EFS provides shared NFS; floating IP enables failover for ASCS/ERS.
- ✗
Amazon EBS volumes attached to both ASCS and ERS instances
Why it's wrong here
EBS volumes cannot be attached to multiple instances for shared access.
