PAS-C01 Technology Practice Question
A company is designing an SAP HANA disaster recovery solution across AWS Regions. The primary site is in us-east-1 and the DR site is in us-west-2. The database size is 5 TB. The RTO is 1 hour and RPO is 15 minutes. Which method should be used for SAP HANA replication?
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 in asynchronous mode to the DR region.
SAP HANA System Replication with asynchronous mode can replicate across regions with RPO of seconds to minutes. Option A is wrong because AWS DMS does not support SAP HANA as a target database. Option B is wrong because synchronous mode over long distances introduces high latency and is not feasible for cross-region replication. Option C is wrong because EBS snapshots alone cannot achieve a 15-minute RPO due to snapshot frequency limits and longer recovery time.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use AWS Database Migration Service (DMS) to continuously replicate changes.
Why it's wrong here
AWS Database Migration Service (DMS) is unsuitable for SAP HANA disaster recovery because it is a logical replication service primarily designed for database migrations and continuous data synchronisation for analytical or reporting purposes, rather than native SAP HANA System Replication. It lacks the tight integration and performance characteristics required to meet the stringent 15-minute RPO for a 5TB HANA database in a cross-Region DR scenario. DMS is tempting as it offers continuous change replication, but its strength lies in facilitating heterogeneous database migrations or establishing data lakes, where the specific RPO and RTO demands of a critical SAP HANA DR solution are not present.
- ✗
Configure SAP HANA System Replication in synchronous mode between the two regions.
Why it's wrong here
Synchronous replication over long distance causes high latency and performance impact.
- ✗
Use AWS Backup to copy EBS snapshots to the DR region every 15 minutes.
Why it's wrong here
Snapshot frequency is limited and restore time may exceed RTO.
- ✓
Configure SAP HANA System Replication in asynchronous mode to the DR region.
Why this is correct
Asynchronous replication allows cross-region replication with acceptable RPO.
