- A
Deploy the SAP application in an Auto Scaling group across multiple AZs and configure SAP HANA System Replication with automatic failover using AWS resources
Auto Scaling for app tier and HSR automatic failover for DB tier provide full automation.
- B
Use Amazon Route 53 health checks to switch DNS to a standby instance in another AZ
Why wrong: DNS switching does not handle database failover automatically.
- C
Deploy the SAP application in an Auto Scaling group across two AZs and use Amazon RDS Multi-AZ for HANA
Why wrong: Amazon RDS does not support SAP HANA; HANA is self-managed.
- D
Deploy the SAP application behind an Application Load Balancer and use SAP HANA System Replication with manual failover scripts
Why wrong: Manual scripts are not automatic.

PAS-C01 Technology 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. 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 customer has a mission-critical system running on AWS. They need to ensure that the SAP application can survive an Availability Zone failure without manual intervention. The SAP application is stateless. The database is SAP HANA with System Replication. What is the most comprehensive architecture to achieve automatic failover?
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 application in an Auto Scaling group across multiple AZs and configure SAP HANA System Replication with automatic failover using AWS resources
Option A is correct because it combines stateless SAP application auto-scaling across multiple Availability Zones (AZs) with SAP HANA System Replication (HSR) configured for automatic failover. HSR uses synchronous replication to keep the standby HANA database in sync, and when combined with AWS services like Amazon Route 53 health checks or a cluster manager (e.g., Pacemaker), the failover occurs automatically without manual intervention. This architecture ensures both the application and database tiers survive an AZ failure seamlessly.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Manual scripts are not automatic.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume Amazon RDS Multi-AZ supports SAP HANA, but RDS Multi-AZ is only available for Amazon Aurora, MySQL, MariaDB, Oracle, PostgreSQL, and SQL Server — not for SAP HANA, which requires native HSR for high availability.
Detailed technical explanation
How to think about this question
SAP HANA System Replication (HSR) with automatic failover typically uses a cluster manager like Pacemaker with STONITH (Shoot The Other Node In The Head) to ensure data consistency and avoid split-brain scenarios. In AWS, this is often implemented using Amazon EC2 Auto Recovery, Elastic IP reassignment, or custom scripts triggered by Amazon CloudWatch alarms, but the key is that the failover must be fully automated at both the application and database layers. A real-world scenario where this matters is during an AZ outage in us-east-1, where the application Auto Scaling group rebalances across remaining AZs while HSR promotes the standby database, all without operator intervention.
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.
