- A
Deploy SAP HANA System Replication across two Availability Zones.
SAP HANA System Replication replicates data between separate HANA instances in different AZs for high availability.
- B
Use a single EBS volume with synchronous replication to both nodes.
Why wrong: EBS volumes cannot be attached to instances in different AZs simultaneously; HANA requires separate storage per node.
- C
Configure EBS Multi-Attach to allow both HANA instances to share the same data volume.
Why wrong: EBS Multi-Attach is limited to a single Availability Zone and does not support cross-AZ replication for HANA.
- D
Implement a cluster manager such as Pacemaker to orchestrate failover.
Pacemaker monitors the HANA instances and automates failover in case of a primary node failure.
- E
Place an Application Load Balancer in front of the HANA database endpoints.
Why wrong: Load balancers are used for application traffic, not for database replication or failover management.
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.
A company is migrating an SAP HANA database to AWS. Which TWO configurations are required to ensure high availability for the SAP HANA database in a multi-AZ setup?
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 SAP HANA System Replication across two Availability Zones.
Option A is correct because SAP HANA System Replication (HSR) is the native mechanism for replicating data between primary and secondary HANA instances across Availability Zones, ensuring synchronous or asynchronous data consistency. This is the foundational requirement for high availability in a multi-AZ setup, as it provides real-time data replication to a standby node in a different AZ.
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 often confuse network-level load balancers (like ALB) with database-specific failover mechanisms, or assume EBS features like Multi-Attach or replication can substitute for HANA-native replication and cluster management.
Detailed technical explanation
How to think about this question
SAP HANA System Replication uses log-based replication where the primary node ships redo log entries to the secondary node, which applies them to maintain a consistent copy. In a multi-AZ deployment, synchronous replication mode ensures zero data loss (RPO=0) by waiting for the secondary to acknowledge each log write before committing on the primary, though this adds latency. Pacemaker, a cluster resource manager, monitors HANA services and automates failover by promoting the secondary to primary using HSR takeover commands, handling fencing and quorum to prevent split-brain scenarios.
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
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.
