PAS-C01 Technology Practice Question
A company is deploying SAP S/4HANA on AWS and needs to ensure that the system can be recovered within 4 hours in case of a disaster in the primary region. The secondary region is in a different AWS region. Which approach should be used to meet the recovery time objective (RTO)?
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 to a secondary region with a pre-provisioned standby instance
Replicating SAP HANA to a standby instance in another region using HANA system replication with pre-provisioned infrastructure allows fast failover. Cross-region EBS snapshots take time to restore. Backup and restore from S3 may be slower. Pilot light with application-level replication is not sufficient for HANA.
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 to a secondary region with a pre-provisioned standby instance
Why this is correct
HANA system replication with pre-provisioned standby allows fast failover, potentially within minutes, meeting the RTO.
- ✗
Use cross-region EBS snapshots and restore them in the secondary region
Why it's wrong here
Restoring EBS snapshots can be time-consuming and may not meet a 4-hour RTO.
- ✗
Back up SAP HANA to Amazon S3 and restore in the secondary region
Why it's wrong here
Restoring from S3 backups can take longer than 4 hours depending on data volume.
- ✗
Set up a pilot light environment using application-level replication
Why it's wrong here
A pilot light environment with application-level replication maintains minimal core infrastructure in the secondary region, but SAP S/4HANA requires full database consistency and complete application stack readiness to resume operations within 4 hours. Pilot light lacks the pre-provisioned compute and storage capacity needed for rapid full recovery, as it only keeps a small replica of critical data. This approach is tempting because it reduces standby costs and works well for non-critical workloads where a longer recovery time is acceptable, such as development or test systems.

AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| 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 |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
