- A
AWS CloudFormation templates to provision the DR infrastructure
Automated provisioning helps meet the 2-hour RTO.
- B
Multi-AZ deployment of the SAP application servers
Why wrong: Multi-AZ is for HA within a region, not cross-region DR.
- C
Amazon S3 Cross-Region Replication for SAP backup files
Ensures backups are available in DR region with low RPO.
- D
Amazon Route 53 health checks and failover routing
Why wrong: Route 53 is important for traffic routing but not essential for meeting RTO/RPO.
- E
Cross-Region replication of EBS snapshots for SAP HANA data volumes
Snapshots can be taken every 15 minutes and replicated to DR region.

PAS-C01 Recovery Time Objective (RTO) Practice Question
This PAS-C01 practice question tests your understanding of operations and maintenance. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: recovery Time Objective (RTO). Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An operations team is planning a disaster recovery (DR) strategy for an SAP system on AWS. The system includes SAP HANA database and application servers. The DR site must have a Recovery Time Objective (RTO) of 2 hours and a Recovery Point Objective (RPO) of 15 minutes. Which THREE components are essential for this DR strategy? (Choose THREE.)
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
✓
AWS CloudFormation templates to provision the DR infrastructure
Correct answers are A, C, and E. CloudFormation templates (A) automate infrastructure provisioning, helping meet the 2-hour RTO. S3 Cross-Region Replication for SAP backup files (C) ensures backups are available in the DR region, supporting RPO. Cross-Region replication of EBS snapshots for SAP HANA data volumes (E) enables frequent snapshots (e.g., every 15 minutes) to meet the RPO. B is wrong because Multi-AZ is for high availability within a region, not cross-region DR. D is wrong because Route 53 health checks and failover routing are important for traffic management but are not essential components for achieving the specified RTO/RPO; they support failover but do not directly provide data replication or infrastructure provisioning.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Recovery Time Objective (RTO)
- Recovery Point Objective (RPO)
- Cross-Region Replication
- Infrastructure as Code (CloudFormation)
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Recovery Time Objective (RTO)
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
Quick reference
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 |
