- A
Implement SAP HANA System Replication (HSR) with two EC2 instances in different Availability Zones.
HSR is SAP's recommended HA solution and supports automatic failover across AZs.
- B
Deploy SAP HANA on Amazon RDS for SAP HANA in Multi-AZ.
Why wrong: Amazon RDS for SAP HANA does not exist.
- C
Use Amazon RDS Multi-AZ for the SAP HANA database.
Why wrong: SAP HANA is not supported on Amazon RDS.
- D
Use a single EC2 instance with EBS snapshots taken every 5 minutes.
Why wrong: Snapshots do not provide automatic failover and have recovery time objectives (RTO) that may be too high.

PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 running SAP S/4HANA on AWS and needs to ensure that the system can survive a single Availability Zone failure. The SAP HANA database is 1.5 TB in size. What is the most cost-effective high availability solution that meets SAP's support requirements?
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 SAP HANA System Replication (HSR) with two EC2 instances in different Availability Zones.
Option A is correct because SAP HANA System Replication (HSR) with two EC2 instances in different Availability Zones provides synchronous replication to meet SAP's support requirements for high availability (HA) while surviving a single AZ failure. This is the most cost-effective solution as it uses standard EC2 instances and does not require additional licensing or managed services, and it supports the 1.5 TB database size without the limitations of RDS for SAP HANA.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Related concept
Read the scenario before looking for a memorised answer.
- ✗
Deploy SAP HANA on Amazon RDS for SAP HANA in Multi-AZ.
Why it's wrong here
Amazon RDS for SAP HANA does not exist.
- ✗
Use Amazon RDS Multi-AZ for the SAP HANA database.
Why it's wrong here
SAP HANA is not supported on Amazon RDS.

Why it's wrong here
Snapshots do not provide automatic failover and have recovery time objectives (RTO) that may be too high.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse Amazon RDS Multi-AZ with a valid option for SAP HANA, but RDS Multi-AZ is not supported for SAP HANA, and AWS does not offer a managed RDS service for SAP HANA, leading to the misconception that a managed database service can be used.
Detailed technical explanation
How to think about this question
SAP HANA System Replication (HSR) uses synchronous replication at the database level, where every transaction is committed on both primary and secondary nodes before acknowledgment, ensuring zero data loss (RPO=0) in a well-configured setup. Under the hood, HSR leverages the SAP HANA log replication mechanism, which can be configured with 'mode=sync' to guarantee consistency, and the secondary instance can be promoted to primary via manual or automated failover using tools like AWS Elastic Load Balancer or custom scripts. In a real-world scenario, this setup is critical for SAP-certified environments, as SAP requires a certified HA solution for production systems, and HSR on EC2 is the only AWS-native option that meets these certification requirements.
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 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.
