- A
Replace the single gp3 volume with multiple io2 Block Express volumes configured in a RAID 0 stripe.
io2 Block Express volumes provide very high IOPS and low latency; RAID 0 stripes I/O across volumes to maximize performance.
- B
Increase the size of the existing gp3 volume to maximize its baseline throughput.
Why wrong: Increasing volume size can improve throughput but not necessarily reduce write latency significantly compared to using provisioned IOPS volumes.
- C
Migrate the database to a larger EC2 instance type with higher network bandwidth.
Why wrong: Larger instance types provide more CPU/memory, but do not directly address EBS write latency.
- D
Move the SAP HANA database to Amazon RDS for SAP HANA.
Why wrong: Amazon RDS does not support SAP HANA; SAP HANA requires direct EC2 deployment.
Quick Answer
The correct answer is to replace the single gp3 volume with multiple io2 Block Express volumes configured in a RAID 0 stripe. This design change most effectively reduces write latency for SAP HANA because RAID 0 distributes I/O operations across multiple volumes, allowing parallel writes that dramatically lower latency, while io2 Block Express volumes provide sub-millisecond latency and higher throughput than gp3. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding that SAP HANA’s write-intensive workload demands both low latency and high IOPS, which a single gp3 volume cannot sustain under peak load. A common trap is assuming that simply increasing gp3 volume size or upgrading the EC2 instance will fix latency, but these do not address the underlying I/O bottleneck. Remember the memory tip: “io2 for I/O, RAID 0 for speed—gp3 alone won’t meet the need.”
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.
A company is running a production SAP HANA database on an AWS EC2 instance with a single EBS gp3 volume. The database frequently experiences high write latency during peak hours. Which design change would MOST effectively 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
Replace the single gp3 volume with multiple io2 Block Express volumes configured in a RAID 0 stripe.
Option C is correct because using multiple EBS io2 Block Express volumes with a RAID 0 stripe distributes the I/O and provides higher throughput and lower latency than a single gp3 volume. Option A (Increase gp3 volume size) might improve throughput but not latency as much as io2. Option B (Switch to a larger EC2 instance) does not directly address disk latency. Option D (Move to Amazon RDS) is not applicable for SAP HANA.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
Detailed technical explanation
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
- 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.
- Use explanations to understand the rule behind the answer.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
