The answer is to migrate /sapmnt to Amazon FSx for NetApp ONTAP. This is correct because FSx for NetApp ONTAP delivers sub-millisecond read latency through its NVMe-based SSD caching and NFSv3 protocol optimizations, directly addressing the high read latency on the shared /sapmnt directory during peak SAP workloads. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding that while Amazon EFS is a valid shared file system for SAP, it can suffer from latency spikes under concurrent read-heavy loads, whereas FSx for NetApp ONTAP is purpose-built for low-latency SAP requirements and is explicitly supported by SAP for /sapmnt. A common trap is to assume increasing EFS throughput or scaling EC2 instances will fix storage latency, but those actions address throughput or compute, not the fundamental I/O path latency. Remember the memory tip: “For /sapmnt, think FSx ONTAP—low latency, SAP-approved, no gaps.”
PAS-C01 Technology Practice Question
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 running an SAP S/4HANA system on AWS. The SAP application is deployed on EC2 instances in a Multi-AZ setup with a shared /sapmnt directory using Amazon EFS. The database is running on Amazon RDS for SAP ASE. Performance monitoring reveals that the /sapmnt volume is experiencing high read latency during peak hours. Which action would most effectively reduce latency?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Migrate /sapmnt to Amazon FSx for NetApp ONTAP.
Option B is correct because switching to Amazon FSx for NetApp ONTAP provides a high-performance shared file system with low-latency access and is fully supported for SAP /sapmnt. Option A (increase EFS throughput) may help but is less effective than using FSx. Option C (ElastiCache) does not replace the file system. Option D (increase instance size) addresses compute, not storage 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.
✓
Migrate /sapmnt to Amazon FSx for NetApp ONTAP.
Why this is correct
FSx for NetApp ONTAP offers consistent low-latency performance and is SAP-certified for /sapmnt.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use Amazon ElastiCache for Redis to cache /sapmnt data.
Why it's wrong here
ElastiCache is for in-memory caching, not a persistent file system for /sapmnt.
✗
Increase the provisioned throughput on the EFS file system.
Why it's wrong here
Increasing EFS throughput can improve performance but may not eliminate latency as effectively as switching to a lower-latency file system.
✗
Increase the size of the EC2 instances running SAP.
Why it's wrong here
Larger instances provide more CPU/memory but do not directly reduce storage latency.
Common exam traps
Common exam trap: answer the scenario, not the keyword
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.

How to think about this question
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.
KKey Concepts to Remember

TExam Day Tips
→Underline the problem statement mentally.
→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.
