- A
Enable data compression on the volume.
Why wrong: Compression adds CPU overhead and may increase latency.
- B
Enable tiering policy to allow all data to be served from the SSD tier.
Moving data to SSD tier reduces latency compared to HDD.
- C
Enable the capacity pool tiering to auto-tier cold data to Amazon S3.
Why wrong: Tiering to S3 increases latency for cold data.
- D
Increase the size of the volume.
Why wrong: Volume size does not directly affect write latency.

PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 environment on AWS uses Amazon FSx for NetApp ONTAP for shared storage. The system is experiencing high write latency. The storage administrator suspects the volume is not optimized for SAP workloads. Which configuration change would most likely reduce write latency?

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 tiering policy to allow all data to be served from the SSD tier.
Option B is correct because enabling the tiering policy to allow all data to be served from the SSD tier ensures that all volume data resides on the high-performance SSD storage pool of the FSx for ONTAP file system. This eliminates read/write latency caused by accessing data from the capacity pool (Amazon S3), which has higher latency. For SAP workloads that require consistent low-latency I/O, keeping all data on the SSD tier is critical to reduce write latency.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable data compression on the volume.
Why it's wrong here
Compression adds CPU overhead and may increase latency.
- ✓
Enable tiering policy to allow all data to be served from the SSD tier.
Why this is correct
Moving data to SSD tier reduces latency compared to HDD.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Enable the capacity pool tiering to auto-tier cold data to Amazon S3.
Why it's wrong here
Tiering to S3 increases latency for cold data.
- ✗
Increase the size of the volume.
Why it's wrong here
Volume size does not directly affect write latency.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse tiering policies with performance optimization, thinking that moving cold data to S3 (Option C) improves performance, when in fact it increases latency for any data that is accessed after being tiered, and does not reduce write latency for active SAP workloads.
Detailed technical explanation
How to think about this question
FSx for ONTAP uses a two-tier storage architecture: an SSD tier (high-performance, low-latency) and a capacity pool tier (Amazon S3, higher latency). By default, data can be tiered to the capacity pool based on access patterns. For SAP workloads, which are sensitive to write latency, disabling tiering or setting the tiering policy to 'all' ensures all data remains on the SSD tier, avoiding the latency penalty of S3 access. This is configured via the volume's tiering policy in the ONTAP CLI or AWS Management Console.
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.
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 |
