The answer is to use an EBS-optimized EC2 instance type, as this provides dedicated network bandwidth specifically for EBS I/O, eliminating contention between storage traffic and other network traffic during peak hours. This directly reduces latency spikes for SAP HANA without incurring any additional cost, since EBS optimization is a standard feature of many current-generation instance types. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding that latency issues in striped LVM setups are often caused by network bottlenecks, not volume size or striping configuration. A common trap is to assume that increasing volume size or switching to RAID 0 will lower latency, but these actions improve throughput or capacity, not the per-I/O delay. Remember the memory tip: “Dedicated beats bigger—EBS-optimized cuts the trigger.”
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 SAP HANA on an EC2 instance. The storage is configured with multiple EBS volumes striped using LVM. The SAP administrator notices that disk I/O latency spikes during peak hours. Which change would MOST effectively reduce latency without incurring additional cost?
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-optimized EC2 instance type
Option B is correct because EBS-optimized instances provide dedicated network bandwidth for EBS I/O, reducing contention. Option A is incorrect because increasing volume size does not directly reduce latency. Option C is incorrect because RAID 0 increases throughput but not lower latency. Option D is incorrect because provisioning IOPS increases cost.
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.
✗
Increase the size of the EBS volumes
Why it's wrong here
Increasing volume size can improve throughput but does not directly reduce latency.
✗
Provision additional IOPS on the EBS volumes
Why it's wrong here
Provisioned IOPS increases cost and may not address latency spikes from network contention.
✗
Switch from LVM to RAID 0 striping
Why it's wrong here
RAID 0 can improve throughput but may not reduce latency.
✓
Use an EBS-optimized EC2 instance type
Why this is correct
EBS-optimized instances provide dedicated bandwidth to EBS, reducing latency.

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.
