PAS-C01 Design of SAP Workloads on AWS Practice Question
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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.
A company runs SAP HANA on AWS and wants to implement a disaster recovery (DR) strategy with a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 2 hours. Which solution meets these requirements?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Elastic Disaster Recovery (DRS) to replicate the HANA server to the DR region.
AWS Elastic Disaster Recovery (DRS) provides continuous block-level replication of the entire SAP HANA server, including OS, application, and data volumes, with sub-minute RPO and RTO of minutes to hours. This meets the 15-minute RPO and 2-hour RTO requirements by enabling rapid failover to a fully provisioned instance in the DR region without manual scaling or data loss from periodic snapshots.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 HANA System Replication (HSR) to a small instance in the DR region and scale up on failover.
Why it's wrong here
HSR has low RPO but scaling up takes more than 2 hours RTO.
✗
Take daily EBS snapshots of the HANA data volumes and copy them to the DR region.
Why it's wrong here
Daily snapshots result in RPO of up to 24 hours, not 15 minutes.
✗
Use AWS Database Migration Service (DMS) to replicate HANA to an RDS instance in the DR region.
Why it's wrong here
DMS is for migration, not for DR with HANA-specific requirements.
✓
Use AWS Elastic Disaster Recovery (DRS) to replicate the HANA server to the DR region.
Why this is correct
DRS provides continuous replication with low RPO.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume HANA System Replication (HSR) is the only valid DR method for SAP HANA on AWS, overlooking that AWS DRS provides a simpler, fully automated solution that meets strict RPO/RTO without requiring HANA-level replication or manual scaling.
Detailed technical explanation
How to think about this question
AWS DRS uses continuous, block-level replication at the storage layer via a lightweight agent installed on the source server, capturing every write I/O and transmitting changes to a staging area in the DR region. This ensures an RPO of seconds to minutes, and upon failover, DRS automatically converts the replicated volumes into a running EC2 instance, typically within 15-30 minutes, well under the 2-hour RTO. In contrast, HSR requires a secondary HANA instance with identical sizing and manual intervention for scale-up, making it unsuitable for rapid DR without pre-provisioned resources.

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
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
