The answer is to use an EBS io2 Block Express volume with provisioned IOPS. This configuration delivers the most consistent I/O performance for SAP HANA write-intensive workloads because io2 Block Express is engineered for single-digit millisecond latency and sustained IOPS, eliminating the performance variability that can occur with gp3 volumes under heavy write pressure. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of storage performance characteristics for latency-sensitive SAP HANA databases, where consistent I/O is critical for transaction throughput. A common trap is assuming that simply increasing gp3 size or adding provisioned IOPS to gp3 will solve latency issues, but gp3’s burst model cannot match the deterministic low-latency architecture of io2 Block Express. Memory tip: for SAP HANA, think “io2 for I/O consistency”—the “2” in io2 reminds you it’s the second-generation volume designed for consistent, predictable performance.
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.
A company is running an SAP HANA database on an EC2 instance with an EBS gp3 volume. The workload is write-intensive and latency-sensitive. Which configuration change would provide the most consistent I/O performance?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use an EBS io2 Block Express volume with provisioned IOPS
Option B is correct because EBS io2 Block Express volumes provide consistent low-latency performance for I/O-intensive workloads like SAP HANA. Option A is incorrect because throughput-optimized HDD (st1) is not suitable for database workloads. Option C is incorrect because increasing gp3 size alone does not guarantee consistent latency. Option D is incorrect because provisioned IOPS on gp3 can help but io2 Block Express is designed for consistent low 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.
✗
Switch to an EBS st1 (throughput-optimized HDD) volume
Why it's wrong here
st1 is not suitable for latency-sensitive database workloads.
✗
Enable EBS Multi-Attach for the gp3 volume
Why it's wrong here
Multi-Attach is not supported for gp3 and is not designed for consistent I/O performance.
✗
Increase the size of the existing gp3 volume to increase baseline throughput
Why it's wrong here
Increasing size does not guarantee consistent latency for write-intensive workloads.
✓
Use an EBS io2 Block Express volume with provisioned IOPS
Why this is correct
io2 Block Express provides consistent low-latency and high IOPS for SAP HANA.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
