- A
Increase the throughput capacity of the FSx file system.
Why wrong: Throughput does not affect file lock behavior.
- B
Enable the file lock duration feature on the FSx file system to automatically release stale locks.
FSx for Windows supports file lock duration to release locks automatically.
- C
The file system is using NFSv3 protocol; switch to NFSv4.
Why wrong: FSx for Windows uses SMB, not NFS.
- D
The file system is using Amazon S3 as the backing store; migrate to EFS.
Why wrong: FSx for Windows File Server does not use S3 as backing store.

PAS-C01 Design of SAP Workloads on AWS Practice Question
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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.
An SAP system uses a shared file system via Amazon FSx for Windows File Server. The system administrators report that file locks are not being released properly, causing application errors. What is the most likely cause and solution?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"most likely"Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
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
✓
Enable the file lock duration feature on the FSx file system to automatically release stale locks.
Amazon FSx for Windows File Server supports a file lock duration feature that can be configured to automatically release stale file locks after a specified timeout. This directly addresses the issue of locks not being released properly, which is a common cause of application errors in SAP systems relying on shared file systems.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Increase the throughput capacity of the FSx file system.
Why it's wrong here

Enable the file lock duration feature on the FSx file system to automatically release stale locks.
Why this is correct
FSx for Windows supports file lock duration to release locks automatically.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse performance tuning (throughput) or protocol changes (NFS vs SMB) with the actual lock management feature, overlooking the specific FSx for Windows File Server capability to automatically release stale locks.
Detailed technical explanation
How to think about this question
FSx for Windows File Server leverages the SMB protocol, which includes opportunistic locking (oplocks) and lease-based locking. The file lock duration feature allows administrators to set a maximum time a lock can be held, after which the lock is automatically released even if the client does not explicitly close the file. This is critical for SAP workloads where application crashes or network interruptions can leave orphaned locks, causing errors like 'file in use' or access denied.
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 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.
