- A
EC2 instance store (NVMe SSD)
Instance store provides very high IOPS, but data is ephemeral; suitable for /hana/data with replication.
- B
Amazon EBS io2 Block Express volumes
io2 Block Express supports up to 256,000 IOPS and is SAP-certified for HANA data.
- C
Amazon S3
Why wrong: S3 is object storage, not block storage, and cannot be used for HANA data volumes.
- D
Amazon EBS gp3 volumes
gp3 can be used for /hana/data if IOPS requirements are moderate, but io2 is preferred.
- E
Amazon EFS
Why wrong: EFS is a file system, not block storage, and is not supported for HANA data.

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 is planning to migrate its SAP HANA database to AWS. The database is 5 TB in size and requires high IOPS for online transaction processing (OLTP) workloads. Which THREE AWS storage options are suitable for SAP HANA data volumes? (Choose THREE.)
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
✓
EC2 instance store (NVMe SSD)
EC2 instance store (NVMe SSD) provides very high IOPS and low latency directly attached to the host, which is suitable for SAP HANA data volumes that require high performance for OLTP workloads. However, instance store is ephemeral, so it must be used with replication or backup strategies for persistence.
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
The trap here is that candidates may confuse Amazon S3 or EFS as suitable for database workloads due to their scalability, but they lack the block-level access and consistent high IOPS required for SAP HANA data volumes.
Detailed technical explanation
How to think about this question
SAP HANA data volumes require block storage with consistent low latency and high IOPS, typically achieved with NVMe-based instance store or EBS io2/io1 volumes. The io2 Block Express volumes offer up to 256,000 IOPS per volume and sub-millisecond latency, while gp3 volumes provide baseline performance with burst capability, making them suitable for non-critical or development HANA workloads. Instance store, though high-performance, is ephemeral and must be used with HANA system replication or backups to avoid data loss.
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 |
