PAS-C01 Operations and Maintenance Practice Question
A company runs SAP on AWS and needs to implement a disaster recovery (DR) strategy. The primary site is in us-east-1, and the DR site is in us-west-2. The database is SAP HANA. Which approach provides the lowest RPO?
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 in synchronous mode across regions.
SAP HANA system replication in synchronous mode across regions provides near-zero RPO (Recovery Point Objective) as data is replicated synchronously to the DR region, ensuring minimal data loss. Option A (asynchronous mode) may have higher RPO due to potential data loss in case of failover. Options B and C (backups to S3 with cross-region replication and EBS snapshots) have significantly higher RPO as they are point-in-time backups, not real-time replication.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SAP HANA system replication in asynchronous mode.
Why it's wrong here
Asynchronous mode may have some data loss, leading to higher RPO.
- ✗
Database backups to S3 and cross-region replication of S3 bucket.
Why it's wrong here
Backups have higher RPO than replication.
- ✗
EBS snapshots replicated to the DR region using cross-region snapshot copy.
Why it's wrong here
Snapshots are point-in-time and have higher RPO.
- ✓
SAP HANA system replication in synchronous mode across regions.
Why this is correct
Synchronous replication ensures data is committed at both sites, minimizing data loss.
