PAS-C01 Technology Practice Question
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?
⚠ Common exam trap
A common mix-up: candidates 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.

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.
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Implement SAP HANA System Replication (HSR) with two EC2 instances in different Availability Zones.
Why this is correct
HSR is SAP's recommended HA solution and supports automatic failover across AZs.
- ✗
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.
- ✗
Use a single EC2 instance with EBS snapshots taken every 5 minutes.
Why it's wrong here
Snapshots do not provide automatic failover and have recovery time objectives (RTO) that may be too high.
