- A
Move database write logs to Amazon S3 for better throughput.
Why wrong: S3 is object storage with higher latency; not suitable for database write logs.
- B
Migrate to io1/io2 EBS volumes with provisioned IOPS.
Provisioned IOPS volumes are designed for consistent, low-latency database workloads.
- C
Migrate to gp3 EBS volumes with higher baseline performance.
Why wrong: gp3 improves but does not guarantee provisioned IOPS for bursty writes.
- D
Use instance store volumes for database data files.
Why wrong: Instance store is ephemeral and not durable; not suitable for database persistence.

PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 application running on AWS is experiencing high latency for database write operations. The system uses SAP ASE on Amazon EC2 with gp2 EBS volumes. Which change is most likely to improve write performance?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:

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
✓
Migrate to io1/io2 EBS volumes with provisioned IOPS.
SAP ASE on Amazon EC2 with gp2 EBS volumes is experiencing high latency for database write operations. gp2 volumes use a burst-bucket model that can exhaust IOPS credits under sustained heavy writes, causing throttled performance. Migrating to io1 or io2 EBS volumes with provisioned IOPS guarantees consistent, low-latency write throughput, which directly addresses the bottleneck for database write workloads.
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.
- ✗
Move database write logs to Amazon S3 for better throughput.
Why it's wrong here
S3 is object storage with higher latency; not suitable for database write logs.
- ✓
Migrate to io1/io2 EBS volumes with provisioned IOPS.
Why this is correct
Provisioned IOPS volumes are designed for consistent, low-latency database workloads.
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.
- ✗
Migrate to gp3 EBS volumes with higher baseline performance.
Why it's wrong here
gp3 improves but does not guarantee provisioned IOPS for bursty writes.
- ✗
Use instance store volumes for database data files.
Why it's wrong here
Instance store is ephemeral and not durable; not suitable for database persistence.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume gp3's higher baseline performance (3000 IOPS vs gp2's 100 IOPS baseline) is sufficient for all workloads, but they overlook that provisioned IOPS volumes are the only AWS block storage option that guarantees consistent performance for latency-sensitive database writes, especially under sustained load.
Detailed technical explanation
How to think about this question
Under the hood, SAP ASE relies on synchronous writes to transaction logs and data files; any I/O latency directly impacts commit times and overall transaction throughput. io1/io2 volumes use a dedicated Nitro controller or EBS-optimized instance path to deliver consistent sub-millisecond latency, while gp2/gp3 rely on a shared burst-bucket or baseline throughput that can degrade under sustained load. In real-world SAP migrations, switching from gp2 to io2 with the correct IOPS-to-GB ratio (e.g., 50:1 for SAP) often reduces write latency by 60-80%.
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.
