The correct answer is to use the Aurora Global Database failover capability to promote the secondary region to primary, as this directly achieves the lowest possible RTO and RPO for regional failures. Aurora Global Database is designed for cross-Region disaster recovery, offering a typical RPO of 1 second and an RTO of 1 minute when you manually promote a secondary cluster—this is the only mechanism that meets the strict recovery objectives in a multi-region active-active architecture. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your understanding that Aurora Global Database failover is a manual operation, not automatic, and that Route 53 health checks or RDS Multi-AZ cannot trigger or replace this cross-Region promotion. A common trap is assuming automatic failover exists for global databases, but the exam emphasizes that you must initiate the promotion yourself. Memory tip: think “1 and 1”—1 second RPO, 1 minute RTO, and 1 manual promotion to make it happen.
SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. 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 designing a multi-region active-active architecture for a web application using Amazon Route 53 latency-based routing. The application runs on EC2 instances in Auto Scaling groups with Application Load Balancers in each region. The application uses an Amazon Aurora global database for its data tier. The architecture must provide the lowest possible RTO and RPO for regional failures. What should the company do to meet 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 the Aurora Global Database failover capability to promote the secondary region to primary.
Aurora Global Database has a typical RPO of 1 second and RTO of 1 minute for regional failover. Failover is initiated by promoting the secondary region's cluster to primary. Option D is correct. Option A is wrong because failover is manual; there's no automatic failover to a cross-Region read replica. Option B is wrong because Route 53 health checks do not trigger Aurora failover. Option C is wrong because RDS Multi-AZ is for single-region HA, not multi-region.
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 Amazon RDS for MySQL with a cross-Region read replica and automatic failover.
Why it's wrong here
RDS MySQL cross-Region replicas require manual promotion.
✗
Use Route 53 health checks to detect regional failure and automatically update the Aurora Global Database endpoint.
Use the Aurora Global Database failover capability to promote the secondary region to primary.
Why this is correct
Aurora Global Database supports managed failover with low RPO/RTO.

✗
Use Amazon RDS Multi-AZ with synchronous replication across Regions.
Why it's wrong here
Multi-AZ is within a single Region, not cross-Region.
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.

Variation 1. A company is designing a multi-region active-active application using Amazon Aurora Global Database. The application must have Recovery Point Objective (RPO) of less than 1 second and Recovery Time Objective (RTO) of less than 1 minute in case of a regional failure. Which configuration meets these requirements?
hard
A.Deploy a single Aurora cluster with a primary in one region and a read replica in the secondary region.
B.Use cross-region read replicas with synchronous replication.
✓ C.Deploy Aurora Global Database with multi-master clusters in two regions.
D.Use Amazon DynamoDB Global Tables instead of Aurora.
Why C: Aurora Global Database uses storage-based replication with typical RPO of seconds, but for sub-second RPO, multi-master with asynchronous replication (option C) is needed. Option A (single-master) has failover time > 1 minute. Option B (DynamoDB Global Tables) is not Aurora. Option D (read replicas cross-region) has higher RPO.
