PAS-C01 Amazon Route 53 Failover Routing Practice Question
A company is migrating a critical SAP HANA database to AWS and needs to ensure high availability. The SAP HANA system replication will be configured across two Availability Zones. Which AWS service should be used to automate the failover of the SAP HANA database?
⚠ Common exam trap
Candidates often select AWS DRS because it replicates data, but for cross-AZ HA of SAP HANA, DNS-based failover with Route 53 is the standard approach. DRS is intended for cross-region DR.

Correct answer & explanation
✓
Amazon Route 53
Amazon Route 53 with failover routing policy and health checks can automate DNS-level failover by directing traffic to the healthy SAP HANA instance. Combined with SAP HANA System Replication across AZs, this provides automated database failover. Option B (AWS CloudFormation) provisions infrastructure but does not automate failover. Option C (AWS Elastic Disaster Recovery) is designed for cross-region disaster recovery, not cross-AZ high availability. Option D (AWS Backup) handles scheduled backups, not real-time failover.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Amazon Route 53
Why this is correct
Correct. Route 53 with failover routing and health checks automates DNS-level failover, redirecting traffic to the standby SAP HANA instance when the primary fails.
- ✗
AWS CloudFormation
Why it's wrong here
Incorrect. CloudFormation is for infrastructure as code, not for automating database failover during an outage.
- ✗
AWS Elastic Disaster Recovery (DRS)
Why it's wrong here
Incorrect. AWS DRS is for disaster recovery across regions or accounts, not for cross-AZ high availability of SAP HANA.
- ✗
AWS Backup
Why it's wrong here
Incorrect. AWS Backup provides scheduled backups, not real-time failover or replication.
