PAS-C01 Technology Practice Question
A company is designing a disaster recovery solution for SAP HANA. The primary site is in us-east-1 and the DR site is in us-west-2. The RPO is 5 minutes and the RTO is 30 minutes. Which replication method meets these requirements?
⚠ Common exam trap
Test-takers frequently confuse AWS-native services like RDS Multi-AZ or DMS with SAP HANA-specific replication, failing to recognize that SAP HANA requires its own replication technology to meet low RPO/RTO and that cross-region replication demands synchronous mode for near-zero data loss.
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
✓
SAP HANA System Replication with synchronous mode
SAP HANA System Replication with synchronous mode is the correct choice because it provides continuous, real-time data replication to the DR site in us-west-2, enabling an RPO of 5 minutes or less and an RTO of 30 minutes. Synchronous replication ensures that every committed transaction is acknowledged by the secondary site before the primary confirms to the application, meeting the strict RPO requirement. This method is purpose-built for SAP HANA and supports automatic failover, which aligns with the 30-minute RTO.
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 RDS Multi-AZ deployment
Why it's wrong here
RDS Multi-AZ is within a single Region, not cross-Region.
- ✗
Scheduled EBS snapshots copied to us-west-2
Why it's wrong here
EBS snapshots have a typical RPO of hours, not 5 minutes.
- ✓
SAP HANA System Replication with synchronous mode
Why this is correct
HANA System Replication can achieve sub-minute RPO synchronously.
- ✗
AWS Database Migration Service with ongoing replication
Why it's wrong here
DMS is not designed for SAP HANA native replication.
