- A
Migrate to a RAID 0+1 configuration with four volumes.
Why wrong: RAID 0+1 adds mirroring, which improves redundancy but does not reduce write latency compared to RAID 0.
- B
Replace gp2 volumes with io1 volumes provisioned with sufficient IOPS for the workload.
io1 volumes provide provisioned IOPS, ensuring consistent low latency for write-intensive workloads.
- C
Increase the volume size of each gp2 volume to 1 TB to increase baseline IOPS.
Why wrong: Increasing gp2 volume size increases baseline IOPS but may not address burst exhaustion; io1 is better for consistent performance.
- D
Move the data to instance store volumes attached to the EC2 instance.
Why wrong: Instance store volumes are ephemeral and data is lost on instance stop/termination, not suitable for persistent database storage.
Quick Answer
The correct answer is to replace the gp2 volumes with io1 volumes provisioned with sufficient IOPS for the workload. This is because SAP HANA is a write-heavy, latency-sensitive database that requires consistent, predictable IOPS, which gp2 volumes cannot guarantee once burst credits are exhausted, whereas io1 delivers provisioned performance regardless of volume size or activity. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding of EBS volume types and their suitability for SAP HANA workloads—a common trap is assuming that increasing gp2 volume size or switching to RAID 0+1 will solve write latency, but those changes only improve baseline IOPS or add cost without addressing the need for sustained, high write throughput. To improve EBS write performance for SAP HANA, always prioritize io1 or io2 Block Express for their consistent IOPS. Memory tip: think “IO1 = I/O One-way to consistent performance,” while gp2 is great for bursty workloads but fails under sustained write pressure.
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 Amazon EBS volumes. The database is experiencing high write latency. The storage is configured as two gp2 volumes in a RAID 0 stripe. Which change is most likely to improve write performance?

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 gp2 volumes with io1 volumes provisioned with sufficient IOPS for the workload.
Option C is correct because io1 volumes provide consistent IOPS performance, which is critical for write-heavy workloads like SAP HANA. Option A is wrong because RAID 0+1 increases cost and complexity without significant write benefit. Option B is wrong because increasing volume size increases baseline IOPS but not burst performance. Option D is wrong because instance store provides ephemeral storage, which is not persistent.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.

Same concept, more angles
2 more ways this is tested on PAS-C01
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. An SAP system is running on an EC2 instance with a single Amazon EBS volume for data and log files. The database administrator wants to increase the IOPS performance without changing the instance type. Which action should be taken?
easy- ✓ A.Modify the EBS volume to provisioned IOPS (io1/io2).
- B.Enable EBS optimization on the EC2 instance.
- C.Change the EC2 instance type to a larger size.
- D.Migrate the data to an instance store volume.
Why A: Option D is correct because you can increase the IOPS of an existing EBS volume by modifying it to a higher IOPS value. Option A is wrong because changing instance type may not be necessary. Option B is wrong because EBS optimization is enabled by default for certain instances. Option C is wrong because you cannot change EBS volume type directly to instance store; instance store is ephemeral.
Variation 2. An SAP ERP system on AWS is experiencing performance degradation. A review shows that the Amazon EBS volumes used for SAP transport directories are gp2 with high throughput but high latency. The SAP team needs improved I/O performance without changing the total storage capacity. Which action should be taken?
hard- A.Change the volume type to gp3 and increase baseline IOPS.
- B.Move the transport directories to instance store volumes.
- C.Enable EBS throughput optimization on the EC2 instance.
- ✓ D.Change the volume type to io2 Block Express with provisioned IOPS.
Why D: Option B is correct because io2 volumes provide consistent low latency. Option A is wrong because gp3 may not be sufficient. Option C is wrong because throughput optimization does not reduce latency. Option D is wrong because instance store is ephemeral.
