- A
Amazon EFS
EFS provides a scalable NFS file system that can be shared across multiple AZs.
- B
Amazon FSx for Windows File Server
Why wrong: FSx for Windows uses SMB, which is not typical for SAP transport directories on Linux.
- C
Amazon EBS with multi-attach enabled
Why wrong: EBS multi-attach is limited to io1/io2 and only works within a single AZ, not across AZs.
- D
Amazon S3
Why wrong: S3 is object storage, not a POSIX-compliant file system for SAP.

PAS-C01 Design of SAP Workloads on AWS Practice Question
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is designing an SAP S/4HANA deployment on AWS with high availability. They want to use a shared file system for the SAP transport directory. Which AWS service should they use for this shared file system?
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 EFS
Amazon EFS is the correct choice because it provides a fully managed, POSIX-compliant, NFS-based shared file system that can be mounted concurrently by multiple EC2 instances across different Availability Zones, which is exactly what an SAP transport directory requires. The SAP transport directory (e.g., /usr/sap/trans) must be accessible from all SAP application servers in the high-availability cluster, and EFS supports the necessary file locking and consistency semantics for SAP's transport management system (TMS).
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Amazon S3
Why it's wrong here
S3 is object storage, not a POSIX-compliant file system for SAP.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Amazon EBS Multi-Attach (which is limited to a single AZ and a small number of instances) with a true multi-AZ shared file system, or they mistakenly think Amazon S3 can be used as a shared file system via a mount point (e.g., s3fs), which lacks the POSIX compliance and locking required for SAP transport directories.
Detailed technical explanation
How to think about this question
Under the hood, Amazon EFS uses the NFSv4.1 protocol, which supports file locking (via NLM) and byte-range locks essential for SAP's transport management system to prevent concurrent write conflicts. In a real-world scenario, the SAP transport directory must be mounted with the 'hard' and 'timeo=600' options to ensure resilience during network interruptions, and EFS's lifecycle management can automatically move infrequently accessed transport files to Infrequent Access storage class to reduce costs.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
