The correct answer is to migrate to EBS io2 Block Express volumes with provisioned IOPS and configure multiple EBS volumes in a RAID 0 striping. These two steps directly address the need for consistent high IOPS and low latency because io2 Block Express delivers up to 256,000 provisioned IOPS per volume with sub-millisecond latency, while RAID 0 striping aggregates the throughput and IOPS of multiple volumes, eliminating the performance inconsistency seen with gp2’s burst-bucket model. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding of SAP HANA storage performance improvement—specifically how to combine high-provisioned IOPS storage with striping to meet SAP’s strict I/O requirements. A common trap is assuming that simply increasing gp2 volume size or relying on EBS optimization (already default) will fix peak-load drops; they won’t. Remember the memory tip: “IO2 for IOPS, RAID 0 for rows”—meaning io2 Block Express handles the IOPS demand, and RAID 0 spreads the data stripes to maximize throughput.
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 runs its SAP HANA database on an EC2 instance with EBS volumes. The database requires consistent high IOPS and low latency. The system is currently using EBS gp2 volumes, but performance is inconsistent during peak loads. Which TWO steps should the administrator take to improve storage performance? (Choose 2)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure multiple EBS volumes in a RAID 0 stripe set.
Options B and D are correct. B: io2 Block Express provides consistent high IOPS. D: Configuring multiple EBS volumes in a RAID 0 striping can increase throughput. A is incorrect because increasing gp2 size only increases baseline IOPS but not consistently. C is incorrect because EBS-optimized instances are enabled by default for current generation. E is incorrect because snapshots degrade performance during creation.
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 existing gp2 volumes to increase baseline IOPS.
Why it's wrong here
A is wrong: gp2 baseline IOPS may still be inconsistent under burst pressure.
✗
Take regular EBS snapshots to improve performance.
Why it's wrong here
E is wrong: snapshots do not improve performance.
✓
Configure multiple EBS volumes in a RAID 0 stripe set.
Why this is correct
D is correct: striping increases aggregate IOPS.

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 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.
