- A
Configure Aurora Global Database with multiple primary clusters, each in a different region, and use Route 53 to route writes.
Why wrong: Aurora Global Database has only one primary cluster.
- B
Use Amazon DynamoDB global tables instead of Aurora Global Database, as DynamoDB supports multi-region writes.
DynamoDB global tables allow active-active multi-region writes. Aurora Global Database does not.
- C
Use Aurora cross-region read replicas and failover to a secondary region for writes.
Why wrong: Read replicas are read-only; failover promotes a replica but does not allow simultaneous writes from multiple regions.
- D
Use Route 53 latency-based routing to direct writes to the nearest region. Each region has its own Aurora cluster.
Why wrong: Latency routing cannot direct writes to a secondary cluster because secondary clusters are read-only.
Quick Answer
The answer is to use Amazon DynamoDB global tables instead of Aurora Global Database, as DynamoDB supports multi-region writes. This is correct because an Aurora Global Database is fundamentally an active-passive architecture: it has a single primary region that handles all writes, while secondary regions are read-only replicas. No amount of routing or endpoint configuration can make those secondary clusters accept writes, so the only way to achieve true multi-region active-active write capability is to switch to a service designed for it, like DynamoDB global tables. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your understanding of Aurora’s architectural limitations versus DynamoDB’s multi-master design. A common trap is assuming that Route 53 latency-based routing or custom endpoints can bypass the single-writer constraint, but the exam expects you to recognize that Aurora Global Database simply cannot support multi-region writes. Memory tip: “Aurora writes from one core; DynamoDB writes from every door.”
SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 application using Amazon Aurora Global Database. The application writes to a custom domain endpoint that routes to the primary cluster. To minimize write latency, the application should write to the nearest region. Which configuration should the solutions architect use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"primary"Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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
Use Amazon DynamoDB global tables instead of Aurora Global Database, as DynamoDB supports multi-region writes.
Option B is correct because an Aurora Global Database has one primary region and multiple secondary regions. The primary region handles all writes; secondary regions are read-only. To allow writes from multiple regions, you would need a different architecture, such as using DynamoDB global tables. Option A is incorrect because Route 53 latency-based routing does not change the fact that only the primary cluster accepts writes. Option C is incorrect because there is only one primary cluster. Option D is incorrect because cross-region read replicas do not accept writes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Related concept

- ✗
Use Aurora cross-region read replicas and failover to a secondary region for writes.
Why it's wrong here
Read replicas are read-only; failover promotes a replica but does not allow simultaneous writes from multiple regions.
- ✗
Use Route 53 latency-based routing to direct writes to the nearest region. Each region has its own Aurora cluster.
Why it's wrong here
Latency routing cannot direct writes to a secondary cluster because secondary clusters are read-only.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.

Same concept, more angles
1 more ways this is tested on SAP-C02
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is designing a multi-region active-active application with a relational database. The application requires strong consistency and read-after-write consistency globally. Which AWS database service should the company choose?
medium- ✓ A.Amazon Aurora Global Database
- B.Amazon RDS for MySQL with Multi-AZ
- C.Amazon DynamoDB Global Tables
- D.Amazon ElastiCache for Memcached
Why A: Amazon Aurora Global Database is designed for multi-region active-active applications requiring strong consistency and read-after-write consistency. It uses a primary region for writes and replicates data to up to five secondary regions with typical latency under one second, while still providing global read-after-write consistency through its storage-based replication layer. This makes it the only AWS relational database service that meets the stated requirements for a multi-region active-active setup with strong consistency.
