PAS-C01 SAP HANA System Replication Practice Question
A company is designing a disaster recovery (DR) strategy for its SAP system on AWS. The primary site is in us-east-1, and the DR site is in us-west-2. The system uses SAP HANA as the database. Which THREE components must be configured to enable a successful DR failover?
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 across regions.
The correct three components are SAP HANA system replication across regions (A), Amazon Route53 DNS failover configuration (B), and AWS Backup cross-region backup copy for the HANA database (C). SAP HANA system replication ensures data consistency and near-synchronous replication between the primary and DR sites. Route53 DNS failover automatically redirects traffic to the DR site in case of a failure. AWS Backup cross-region copy provides an additional backup of the HANA database in the DR region, ensuring backup availability. Option D (S3 Cross-Region Replication) is not essential for HANA replication; transport files can be handled separately. Option E (AWS Transit Gateway peering) provides network connectivity but is not a DR failover component.
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 across regions.
Why this is correct
SAP HANA system replication across regions ensures data consistency and near-synchronous replication for DR failover.
- ✓
Amazon Route53 DNS failover configuration.
Why this is correct
Amazon Route53 DNS failover configuration enables automatic traffic rerouting to the DR site during a failure.
- ✓
AWS Backup cross-region backup copy for the HANA database.
Why this is correct
AWS Backup cross-region backup copy for the HANA database provides additional backup availability in the DR region.
- ✗
S3 Cross-Region Replication for SAP transport files.
Why it's wrong here
S3 Cross-Region Replication for SAP transport files is not required for HANA replication; transport files can be replicated separately.
- ✗
AWS Transit Gateway peering between the two regions.
Why it's wrong here
AWS Transit Gateway peering is for network connectivity, not for DR failover.

| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
