- A
Amazon Elastic File System (EFS)
Why wrong: EFS is a scalable NFS file system but not the most cost-effective for SAP transport directories; FSx for NetApp ONTAP is more suitable.
- B
Amazon EBS Multi-Attach gp3 volume
Why wrong: EBS Multi-Attach is limited to a single AZ and doesn't provide cross-AZ failover.
- C
Amazon FSx for NetApp ONTAP
FSx for NetApp ONTAP provides a fully managed NFS share with cross-AZ HA, suitable for SAP transport directories.
- D
Amazon S3 with AWS Storage Gateway file gateway
Why wrong: S3 is object storage and not ideal for shared file systems requiring low latency.
Question 944 of 1,733
Cost-Effective Shared File System for SAP Transport Directories with FSx for NetApp ONTAP
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
An SAP Basis team is designing a high-availability (HA) setup for SAP NetWeaver on AWS. They plan to use a shared file system for transport directories. Which storage solution provides the most cost-effective NFS share with support for automatic failover across Availability Zones?
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 NetApp ONTAP
Amazon FSx for NetApp ONTAP is the correct choice because it provides a fully managed, highly available NFS share that supports automatic failover across Availability Zones (AZs) using NetApp's SnapMirror and multi-AZ HA pair architecture. It is the most cost-effective solution for SAP transport directories that require a shared file system with cross-AZ failover, as it offers native NFSv3/v4.1 support, consistent performance, and lower total cost of ownership compared to alternatives for this specific SAP workload.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume Amazon EFS is the default choice for any NFS workload on AWS due to its simplicity and regional failover, but they overlook that FSx for NetApp ONTAP is specifically optimized for SAP workloads with better cost efficiency and performance consistency for transport directories, making it the correct answer in this context.
Detailed technical explanation
How to think about this question
Under the hood, FSx for NetApp ONTAP uses a high-availability (HA) pair of file servers in two separate AZs, with synchronous replication of data between them, enabling automatic failover in under 30 seconds without data loss. For SAP transport directories, this ensures that the shared /usr/sap/trans directory remains accessible during an AZ failure, leveraging NetApp's proven ONTAP file system that supports NFSv3 and v4.1 with consistent low-latency performance. In real-world scenarios, SAP Basis teams often choose FSx for NetApp ONTAP over EFS because it offers deduplication, compression, and snapshots that reduce storage costs for large transport directories, while EFS lacks these features and can incur higher costs for similar performance.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
