PAS-C01 Amazon EFS Practice Question
This PAS-C01 practice question tests your understanding of migration. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: amazon EFS. 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 SAP application servers use a shared /sapmnt filesystem. Which AWS storage solution is most suitable for this shared filesystem with 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
Option D (Amazon EFS) is correct because Amazon EFS is a managed NFS filesystem that provides high availability and can be shared across multiple EC2 instances, making it suitable for the shared /sapmnt filesystem required by SAP. Option A (Amazon S3) is wrong because S3 is object storage, not a POSIX-compliant filesystem, and cannot be mounted as a shared filesystem. Option B (Amazon FSx for Windows File Server) is incorrect because SAP typically runs on Linux, and FSx for Windows is designed for Windows workloads. Option C (Amazon EBS with Multi-Attach) is not ideal because EBS Multi-Attach has limitations (max 16 instances, single Availability Zone) and is not as scalable or resilient as EFS for this use case.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The /sapmnt filesystem must be accessible from multiple application servers simultaneously. While EBS Multi-Attach can technically attach a volume to multiple instances, it is not recommended for SAP workloads due to limited concurrency and lack of managed high availability. EFS is the correct choice.
Detailed technical explanation
How to think about this question
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.

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

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.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
