The correct choice is to design the application to handle eventual consistency using conditional writes and application logic. DynamoDB global tables replicate data asynchronously across regions, which inherently means they only support eventual consistency; there is no toggle or configuration for strong consistency reads across regions. To meet the requirement, the application must implement its own consistency guarantees by using conditional writes to check the latest state before updating and by incorporating conflict resolution logic at the application layer. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your understanding of distributed system trade-offs and the limitations of global tables—a common trap is assuming DAX or DynamoDB Streams can enforce strong consistency, but DAX is a cache and Streams is for change data capture, not consistency. Remember the key memory tip: global tables are eventually consistent by design, so you must build strong consistency into your application code, not the database.
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 DynamoDB global tables. The application requires strong consistency reads. However, global tables only support eventual consistency. What should the solutions architect do to meet the requirement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Design the application to handle eventual consistency using conditional writes and application logic.
Option A is correct. DynamoDB global tables use eventual consistency, but the application can use conditional writes and application-level conflict resolution to achieve strong consistency. Option B is wrong because DynamoDB Accelerator (DAX) is a cache, not a consistency mechanism. Option C is wrong because DynamoDB Streams is for change data capture. Option D is wrong because there is no configuration for strong consistency in global tables.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Global tables do not support strong consistency.
✗
Use DynamoDB Streams to replicate data to another region with strong consistency.
Why it's wrong here
Streams do not provide strong consistency.
✗
Use DynamoDB Accelerator (DAX) to provide strong consistency reads.
Why it's wrong here
DAX does not provide strong consistency across regions.
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.
