Quick Answer
The answer is Amazon EFS, as it provides a low-latency, shared file system for SAP transport directories that can be accessed concurrently from multiple EC2 instances across different Availability Zones. This works because EFS is a fully managed NFS file system designed for high throughput and consistent performance, making it ideal for SAP’s requirement of a POSIX-compliant, multi-AZ shared mount. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding of storage services for SAP landscapes, where the common trap is confusing EBS (single-instance attachment) or S3 (object storage) with a true shared file system. Remember that SAP transport directories need a network file system, not block or object storage. Memory tip: think “EFS = Elastic File System for SAP’s multi-AZ transport needs.”
This PAS-C01 practice question tests your understanding of technology. 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.
A company is migrating an SAP ERP system to AWS. The system requires low-latency access to a shared file system for SAP transport directories. The file system must be accessible from multiple EC2 instances in different Availability Zones. Which storage solution meets these requirements?
Amazon EBS volumes snapshotted and shared across instances.
Why wrong: EBS volumes are single-instance attachments.
Instance store volumes on each EC2 instance.
Why wrong: Not persistent or shared.
Amazon S3 with Transfer Acceleration.
Why wrong: Object storage, not a file system.
Amazon EFS file system.
Provides shared, low-latency file system across AZs.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon EFS file system.
Option C is correct because Amazon EFS provides a shared file system accessible from multiple AZs with low latency. Option A is wrong because instance store is ephemeral and not shared. Option B is wrong because EBS volumes can only be attached to one instance at a time. Option D is wrong because S3 is object storage, not a file system.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
