Quick Answer
The answer is Amazon EFS. This is the correct choice because SAP NetWeaver requires a shared file system that supports POSIX permissions and file locking semantics for the transport directory and SAP profiles, which must be concurrently accessible from multiple EC2 instances across different Availability Zones. Amazon EFS provides a fully managed, NFS-based solution that meets these requirements natively, whereas services like Amazon EBS cannot be shared across zones and Amazon S3 lacks the necessary file-level locking. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of shared storage requirements for SAP high-availability architectures—a common trap is choosing Amazon FSx for Windows File Server, but SAP on Linux requires NFSv4 with POSIX compliance, which EFS delivers. A useful memory tip: think of EFS as the “elastic file share” for SAP’s transport and profile directories, ensuring cross-AZ access without manual replication.
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.
An SAP Basis team is designing a high-availability architecture for SAP NetWeaver on AWS. They plan to use a shared file system for the transport directory and SAP profiles across multiple availability zones. Which AWS storage service should they use?
Amazon EBS with multi-attach
Why wrong: EBS multi-attach is limited to a single AZ and not across AZs.
Amazon FSx for Windows File Server
Why wrong: FSx for Windows is for Windows, not typical for SAP on Linux.
Amazon EFS
EFS provides a shared NFS file system across AZs.
Amazon S3
Why wrong: S3 is not a file system; it's object storage.

Correct answer & explanation
Amazon EFS
Amazon EFS (Elastic File System) is the correct choice because it provides a fully managed, NFS-based shared file system that is accessible from multiple EC2 instances across different Availability Zones. For SAP NetWeaver, the transport directory and SAP profiles must be concurrently accessible from all application servers in a high-availability setup, and EFS supports the required POSIX permissions and locking semantics needed by SAP.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Amazon EBS with multi-attach
Why it's wrong here
EBS multi-attach is limited to a single AZ and not across AZs.
Amazon FSx for Windows File Server
Why it's wrong here
FSx for Windows is for Windows, not typical for SAP on Linux.
Amazon EFS
Why this is correct
EFS provides a shared NFS file system across AZs.

Amazon S3
Why it's wrong here
S3 is not a file system; it's object storage.
Common exam traps
The trap here is that candidates often confuse Amazon EBS Multi-Attach (option A) as a viable cross-AZ solution, but it is strictly single-AZ, making it incompatible with the multi-AZ high-availability requirement for SAP NetWeaver.
Detailed technical explanation
Under the hood, Amazon EFS uses the NFSv4.1 protocol with support for file locks (including advisory and mandatory locking via flock and fcntl), which are critical for SAP's transport management system (TMS) to prevent concurrent write conflicts. A real-world scenario where this matters is during an SAP system copy or transport import, where multiple application servers must simultaneously read and write to the same transport directory without data corruption. EFS also provides automatic scaling of throughput and storage capacity, eliminating the need for manual provisioning as the transport directory grows.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
