This PAS-C01 practice question tests your understanding of technology. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 is planning to migrate its SAP landscape to AWS. The SAP systems include a production system, a QA system, and a development system. All systems use the same SAP S/4HANA version. Which strategy is MOST cost-effective for the DR (disaster recovery) setup?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use cross-Region replication with AWS reserved instances for the DR systems.
Option D is correct because cross-Region replication for DR using a single reserved instance for each system is cost-effective compared to running full active instances. Option A (Active-active) would incur double cost. Option B (Pilot light) would require starting instances on failure, impacting RTO. Option C (Warm standby) is more expensive than cross-Region replication with reserved instances.
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.
✗
Set up warm standby in a second Region with a standby application server and database.
Why it's wrong here
Warm standby incurs ongoing costs for the standby infrastructure.
✓
Use cross-Region replication with AWS reserved instances for the DR systems.
Why this is correct
Reserved instances provide significant discount over on-demand, making this the most cost-effective option for DR.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use a pilot light strategy with AWS DMS ongoing replication.
Why it's wrong here
Pilot light is less expensive but not as cost-effective as cross-Region replication with reserved instances, and DMS adds cost.
✗
Deploy active-active SAP systems in two AWS Regions with Elastic Load Balancing.
Why it's wrong here
Active-active is expensive and SAP licensing may not allow active-active for the same system ID.
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
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
