PAS-C01 Operations and Maintenance Practice Question
This PAS-C01 practice question tests your understanding of operations and maintenance. 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 on AWS and needs to implement a disaster recovery (DR) strategy that meets a Recovery Point Objective (RPO) of 15 minutes and a Recovery Time Objective (RTO) of 2 hours. The DR region must have the SAP application stack ready but the database can be replayed from backups. Which TWO actions should be taken to meet these requirements? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set up a cross-region read replica for the Aurora PostgreSQL database.
Options A and D are correct. A cross-region read replica for Aurora PostgreSQL provides near-real-time replication meeting the 15-minute RPO. Pre-provisioning EC2 instances in the DR region reduces RTO. Option B (cross-region snapshot) may have higher RPO. Option C (single-region) does not meet DR requirements. Option E (S3 cross-region replication) is for files, not database.
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.
✗
Use a single-region Multi-AZ deployment for the database.
Why it's wrong here
Multi-AZ is for high availability, not disaster recovery across regions.
✗
Use S3 cross-region replication for the application log files.
Why it's wrong here
This does not address database replication required for RPO.
✓
Set up a cross-region read replica for the Aurora PostgreSQL database.
Why this is correct
Cross-region read replicas provide low RPO (usually seconds) and can be promoted quickly.

Read the scenario before looking for a memorised answer.
✗
Take daily snapshots of the database and copy them to the DR region.
Why it's wrong here
Daily snapshots do not meet the 15-minute RPO.
✓
Pre-provision EC2 instances with the SAP application stack in the DR region.
Why this is correct
Pre-provisioning reduces RTO as the infrastructure is ready.

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 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.
