Quick Answer
The answer is RAID 10 for SAP HANA data volumes on AWS. This configuration combines striping and mirroring, delivering both the high I/O throughput required for HANA’s demanding workloads and the redundancy needed to protect against an EBS volume failure. RAID 0 offers no fault tolerance, while RAID 5 and RAID 6 introduce significant write penalties due to parity calculations, which can degrade HANA’s performance. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of storage architecture for SAP HANA on EC2, often appearing as a straightforward scenario where you must distinguish between performance and protection. A common trap is choosing RAID 0 for speed alone, forgetting that HANA data volumes require mirroring for resilience. Memory tip: “10” for HANA data—think “1” for mirroring and “0” for striping, giving you both safety and speed.
This PAS-C01 practice question tests your understanding of technology. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
An SAP system administrator is configuring an SAP HANA database on an EC2 instance with multiple EBS volumes. The administrator wants to ensure that the data volumes are mirrored to protect against volume failure. Which RAID configuration should the administrator use for the HANA data volumes?
RAID 5
Why wrong: RAID 5 has parity write penalty and is not recommended for HANA.
RAID 0
Why wrong: RAID 0 has no redundancy; failure of one volume causes data loss.
RAID 10
RAID 10 combines mirroring and striping for performance and redundancy.
RAID 6
Why wrong: RAID 6 has double parity write penalty, not optimal.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
RAID 10
Option A is correct because RAID 10 (striping + mirroring) provides both performance and redundancy, recommended for HANA data. Option B is wrong because RAID 0 provides no redundancy. Option C is wrong because RAID 5 has write penalty. Option D is wrong because RAID 6 has higher write penalty.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

RAID 0
Why it's wrong here
RAID 0 has no redundancy; failure of one volume causes data loss.
RAID 10
Why this is correct
RAID 10 combines mirroring and striping for performance and redundancy.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
