PAS-C01 Design of SAP Workloads on AWS Practice Question
A company plans to migrate their SAP HANA database to AWS. They require the highest availability with automatic failover in case of an AZ failure. Which architecture should they use?
⚠ Common exam trap
Watch out — candidates often confuse 'high availability' with 'disaster recovery' and select a backup-only option (C) or a Single AZ option (B), failing to recognize that automatic failover across AZs requires both Multi-AZ deployment and synchronous replication with automated takeover.

Correct answer & explanation
✓
Multi-AZ with HANA System Replication in sync mode and automatic failover.
It meets the requirement for highest availability with automatic failover in case of an AZ failure. HANA System Replication (HSR) in synchronous mode ensures zero data loss (RPO=0) by committing transactions only after they are replicated to the standby, and when combined with Multi-AZ deployment, it provides automatic failover across Availability Zones. This architecture is the AWS-recommended pattern for SAP HANA high availability, leveraging the AWS Multi-AZ concept with HSR's built-in automatic takeover capability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Multi-AZ with HANA System Replication in sync mode and automatic failover.
Why this is correct
Provides automatic failover across AZs.
- ✗
Single AZ with HANA System Replication to a standby in the same AZ.
Why it's wrong here
Does not protect against AZ failure.
- ✗
Single AZ with daily backups to Amazon S3.
Why it's wrong here
Backup & Restore has high RTO, not automatic.
- ✗
Multi-AZ with HANA System Replication in async mode and manual failover.
Why it's wrong here
Manual failover is not automatic.
