PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is designing a disaster recovery strategy for SAP S/4HANA. The primary site is in us-east-1 and the DR site is in us-west-2. The RPO must be less than 30 minutes and RTO less than 2 hours. Which approach meets these requirements?
⚠ Common exam trap
Watch out — candidates often confuse synchronous mode as more reliable for DR, but fail to recognize that cross-region latency makes synchronous replication impractical, while asynchronous mode with automatic takeover is the standard AWS-recommended approach for SAP HANA disaster recovery.

Correct answer & explanation
✓
Configure HANA System Replication in asynchronous mode with automatic takeover
HANA System Replication in asynchronous mode with automatic takeover meets the RPO of less than 30 minutes and RTO of less than 2 hours. Asynchronous replication provides near-real-time data transfer across AWS regions with minimal impact on primary performance, and automatic takeover enables fast failover to the DR instance, satisfying the RTO requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure HANA System Replication in asynchronous mode with automatic takeover
Why this is correct
Async replication can meet <30 min RPO and with pre-provisioned DR instances, RTO <2 hours.
- ✗
Configure HANA System Replication in synchronous mode across regions
Why it's wrong here
Synchronous mode not feasible due to latency across regions.
- ✗
Take nightly backups to S3 and restore in DR
Why it's wrong here
RPO > 30 minutes and RTO > 2 hours.
- ✗
Use AWS Backup to copy daily snapshots to DR region
Why it's wrong here
Daily snapshots exceed RPO of 30 minutes.
