- A
Move the SAP HANA instance to a larger instance type to improve hardware reliability.
Why wrong: Larger instances do not mitigate AZ-level failures.
- B
Deploy the SAP HANA database in a Multi-AZ configuration using SAP HANA System Replication (HSR) across Availability Zones.
Deploy the SAP HANA database in a Multi-AZ configuration using SAP HANA System Replication (HSR) across Availability Zones, providing automatic failover without downtime.
- C
Use Dedicated Hosts to ensure physical isolation from other AWS customers.
Why wrong: Dedicated Hosts still operate within a single AZ.
- D
Implement automated snapshots of the SAP HANA data volume and restore in case of failure.
Why wrong: Snapshot restore has longer RTO compared to Multi-AZ automatic failover.

PAS-C01 SAP HANA System Replication (HSR) Practice Question
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. A key principle to apply: sAP HANA System Replication (HSR). 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 running a critical SAP application on SAP HANA in an AWS Single-AZ deployment. The application has experienced downtime twice in the last month due to underlying hardware failures. What is the MOST cost-effective solution to minimize future downtime without compromising performance?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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
✓
Deploy the SAP HANA database in a Multi-AZ configuration using SAP HANA System Replication (HSR) across Availability Zones.
Option B is correct because deploying SAP HANA in a Multi-AZ configuration using SAP HANA System Replication (HSR) across Availability Zones provides synchronous replication and automatic failover in case of hardware failure. This minimizes downtime without requiring a larger instance or manual intervention, and maintains performance by using the same instance type and storage configuration as the primary.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS RDS Multi-AZ with SAP HANA's HA approach. SAP HANA uses its own System Replication (HSR) across AZs, not a managed AWS service like Multi-AZ DB instance. The key is understanding that AWS provides infrastructure for HSR, but the replication is managed by SAP HANA itself.
Detailed technical explanation
How to think about this question
AWS Multi-AZ for SAP HANA uses synchronous replication at the storage layer (EBS) to maintain a standby instance in a different Availability Zone, with automatic failover handled by the SAP HANA system replication or AWS-managed services. Under the hood, this leverages the SAP HANA system replication protocol (based on log shipping and synchronous replication) to ensure zero data loss (RPO=0) and a typical RTO of less than 1 minute during a failover event. In a real-world scenario, a single-AZ deployment on a large instance (e.g., r5.24xlarge) still experiences downtime if the underlying hardware fails, whereas Multi-AZ ensures continuous availability even if an entire AZ becomes unavailable.

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.

Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
