This PAS-C01 practice question tests your understanding of technology. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Which TWO AWS services can be used to provide shared storage for SAP systems running on multiple EC2 instances?
EC2 Instance Store
Why wrong: Instance store is ephemeral and local to one instance.
Amazon S3
Why wrong: S3 is object storage, not a file system.
Amazon EBS
Why wrong: EBS volumes can only attach to one instance.
Amazon FSx for NetApp ONTAP
FSx for ONTAP provides shared NFS/SMB storage.
Amazon EFS
EFS is a scalable NFS file system for Linux.
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 FSx for NetApp ONTAP
Options A and D are correct. Amazon EFS provides NFS shared storage for Linux instances. Amazon FSx for NetApp ONTAP provides NFS and SMB shared storage. Option B is incorrect because EBS volumes cannot be attached to multiple instances. Option C is incorrect because S3 is object storage, not a file system. Option E is incorrect because Instance Store is ephemeral and not shared.
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.
