PAS-C01 Technology Practice Question
A company is running SAP Business Suite on AWS and wants to improve the disaster recovery posture by replicating data to another AWS Region. The solution must have a recovery time objective (RTO) of less than 15 minutes and a recovery point objective (RPO) of less than 5 minutes. Which approach should they take?
⚠ Common exam trap
Candidates often confuse AWS-native replication services (like DMS, S3 CRR, or AWS Backup) with SAP-specific replication mechanisms, assuming any continuous replication can meet the strict RPO/RTO, but only SAP HANA system replication is designed for sub-minute failover and near-zero data loss for SAP workloads.
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
✓
Configure SAP HANA system replication with synchronous mode.
SAP HANA system replication in synchronous mode ensures that every committed transaction is replicated to the secondary region before acknowledging the commit, achieving an RPO of effectively zero (less than 5 minutes) and enabling rapid failover within seconds, meeting the RTO of under 15 minutes. This is the only native SAP solution that provides the required low-latency, consistent replication for SAP Business Suite on AWS.
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 SAP HANA system replication with synchronous mode.
Why this is correct
Synchronous HANA replication ensures data is copied to the secondary before commit, achieving low RPO and RTO.
- ✗
Use AWS Database Migration Service for continuous replication.
Why it's wrong here
DMS is for homogeneous/heterogeneous migrations, not designed for sub-5 minute RPO.
- ✗
Use Amazon S3 cross-Region replication for transaction logs.
Why it's wrong here
S3 replication has eventual consistency and may not meet RPO.
- ✗
Use AWS Backup to create cross-Region EBS snapshots every 5 minutes.
Why it's wrong here
Snapshots are point-in-time and cannot achieve <5 minute RPO consistently.
