PAS-C01 Technology Practice Question
A company is running SAP HANA on an EC2 instance. The storage is provided by multiple EBS volumes. Which THREE considerations are important when configuring EBS volumes for SAP HANA? (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
✓
Use RAID 0 striping across multiple EBS volumes to increase throughput.
Options A, C, and E are correct. Option A is correct because using RAID 0 striping across multiple EBS volumes increases aggregated throughput and IOPS, which benefits SAP HANA workloads. Option C is correct because separating data and log volumes prevents I/O contention and aligns with SAP best practices. Option E is correct because SAP HANA requires consistent, sufficient IOPS; provisioning volumes with adequate provisioned IOPS meets performance requirements. Option B is incorrect because gp2 burst credits are not reliable for production HANA; provisioned IOPS volumes (e.g., io1/io2) or gp3 are recommended. Option D is incorrect because EBS bursting introduces variability and is not suitable for production HANA; volumes should be sized for baseline performance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use RAID 0 striping across multiple EBS volumes to increase throughput.
Why this is correct
RAID 0 improves performance by combining multiple volumes.
- ✗
Use gp2 volumes with burst credits to handle peak IOPS.
Why it's wrong here
Burst credits can lead to inconsistent performance; provisioned IOPS volumes are recommended.
- ✓
Separate data and log volumes to avoid I/O contention.
Why this is correct
SAP HANA requires separate volumes for data and log files.
- ✗
Enable EBS bursting for all volumes to ensure high throughput.
Why it's wrong here
Bursting is not reliable for production workloads; provisioned IOPS are better.
- ✓
Provision EBS volumes with sufficient IOPS to meet SAP HANA performance requirements.
Why this is correct
HANA needs consistent IOPS; use io1 or io2 volumes.
Quick reference
RAID Level Comparison
| RAID Level | Min Disks | Fault Tolerance | Read | Write | Usable Capacity |
|---|---|---|---|---|---|
| RAID 0 | 2 | None | Excellent | Excellent | 100% |
| RAID 1 | 2 | 1 disk | Good | Moderate | 50% |
| RAID 5 | 3 | 1 disk | Good | Moderate | 67–94% |
| RAID 6 | 4 | 2 disks | Good | Lower | 50–88% |
| RAID 10 | 4 | 1 disk per mirror | Excellent | Good | 50% |
RAID is not a backup strategy — it protects against disk failure but not against accidental deletion, ransomware, or site-level events.
