- A
Implement automatic failover using SAP HANA System Replication.
Automatic failover is a key HA feature.
- B
Use Amazon RDS for HANA with Multi-AZ deployment.
Why wrong: RDS does not support HANA.
- C
Take daily snapshots of the HANA data volume.
Why wrong: Backups are for disaster recovery, not HA.
- D
Configure SAP HANA System Replication across two Availability Zones.
Multi-AZ HSR provides high availability.
- E
Use a larger EC2 instance type for the HANA server.
Why wrong: Scaling up does not improve availability.
Question 641 of 1,733
Valid Strategies to Improve SAP HANA Availability
This PAS-C01 practice question tests your understanding of technology. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Which TWO of the following are valid strategies to improve the availability of an SAP HANA database on AWS?
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
✓
Implement automatic failover using SAP HANA System Replication.
Option A is correct because SAP HANA System Replication (HSR) provides synchronous or asynchronous replication of the HANA database to a secondary system. Automatic failover can be configured using HSR with tools like Pacemaker or AWS-specific scripts, ensuring high availability by switching to the standby instance if the primary fails. This is a native SAP HANA feature that does not rely on external services.
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 may confuse backup strategies (snapshots) or performance scaling (larger instances) with high availability, or incorrectly assume Amazon RDS supports SAP HANA, when in fact HANA requires manual EC2 deployment and native replication features.
Detailed technical explanation
How to think about this question
SAP HANA System Replication uses log shipping and replay to keep the secondary database synchronized; in synchronous mode, every transaction is committed on both primary and secondary before acknowledging the client, ensuring zero data loss. For automatic failover, a cluster manager like Pacemaker monitors the HANA health and can trigger a takeover by promoting the secondary to primary, often within minutes. In a real-world scenario, cross-AZ HSR (Option D) protects against entire AZ failures, while same-AZ HSR protects against instance or host failures, and both are valid strategies for improving availability.
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.
