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 wants to migrate its on-premises SAP system to AWS. The system consists of an SAP NetWeaver application server and an SAP HANA database. The database requires ultra-low latency storage. Which AWS storage solution is most suitable for the SAP HANA data volume?

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 volumes
Amazon EBS io2 Block Express volumes are the most suitable storage solution for SAP HANA data volumes because they provide ultra-low latency, high durability, and up to 256,000 IOPS per volume with sub-millisecond latency. This meets the stringent performance requirements of SAP HANA, which demands consistent, low-latency storage for its in-memory database operations. io2 Block Express is certified by SAP for production HANA workloads on AWS.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Amazon EFS file system
Why it's wrong here
EFS is not block storage and has higher latency.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse EC2 Instance Store's low latency with durability, overlooking that SAP HANA requires persistent, non-ephemeral storage for production data.
Detailed technical explanation
How to think about this question
EBS io2 Block Express volumes leverage a Nitro-based architecture that enables direct attachment to instances via NVMe, achieving up to 256,000 IOPS and 4,000 MB/s throughput per volume with 99.999% durability. SAP HANA relies on persistent storage for redo logs and data snapshots, and io2 Block Express provides the consistent sub-millisecond latency and high IOPS necessary to prevent database checkpoint bottlenecks. In real-world deployments, using io2 Block Express for /hana/data and /hana/log volumes ensures compliance with SAP's storage KPI requirements.
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 |
