- A
Amazon S3
Why wrong: Amazon S3 is object storage; latency is too high for SAP HANA database files.
- B
Amazon EBS st1
Why wrong: st1 is throughput-optimized and not designed for low-latency database workloads.
- C
Amazon EBS io2 Block Express
io2 Block Express provides up to 256000 IOPS and can be modified without downtime.
- D
Amazon EBS gp3
Why wrong: gp3 volumes have lower maximum IOPS compared to io2.
Question 26 of 1,733
Choose EBS io2 Block Express for SAP HANA Data Volume Performance and Scalability
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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 migrating an SAP HANA database to AWS. The system requires a high-performance storage solution with low latency for database files, and the storage must be scalable without downtime. Which AWS storage solution should the company use for the SAP HANA data volume?
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
✓
Amazon EBS io2 Block Express
Amazon EBS io2 Block Express is the correct choice because it provides up to 256,000 IOPS per volume with sub-millisecond latency, meeting SAP HANA's strict performance requirements for data volumes. It also supports Elastic Volumes, allowing you to scale storage capacity and performance without downtime, which is critical for production SAP HANA systems.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Amazon EBS gp3
Why it's wrong here
gp3 volumes have lower maximum IOPS compared to io2.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose gp3 for its lower cost and good baseline performance, overlooking that SAP HANA's certification requires io2 Block Express (or io1) for production data volumes due to the need for guaranteed high IOPS and sub-millisecond latency under sustained load.
Detailed technical explanation
How to think about this question
Amazon EBS io2 Block Express volumes use a dedicated Nitro-based block storage architecture that communicates directly with the EC2 instance via NVMe over PCIe, bypassing the hypervisor to achieve consistent single-digit millisecond latency. For SAP HANA, the data volume must sustain high IOPS for checkpoint operations and log writes; io2 Block Express supports up to 64 TiB per volume and 1,000 IOPS per GiB, making it the only EBS volume type certified for SAP HANA production workloads on AWS.
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.
TExam Day Tips
- 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.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
