The correct strategies to reduce write conflicts in DynamoDB global tables are implementing application-level conflict resolution and using conditional writes. Conditional writes prevent overwrites by ensuring a write operation only succeeds when a specified condition is met, such as checking that a version number matches, which directly minimizes the chance of conflicting updates across regions. Application-level conflict resolution then handles any remaining conflicts by allowing your code to merge or reconcile divergent data, rather than relying on the default last-writer-wins behavior that can silently discard updates. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this question tests your understanding of how global tables manage concurrent writes and the trade-offs between consistency and availability. A common trap is assuming that increasing write capacity units reduces conflicts—it does not, because conflicts stem from concurrent updates to the same item, not throughput limits. Remember the mnemonic “CARE”: Conditional writes and Application-level Resolution are the Effective pair for conflict reduction.
DOP-C02 Resilient Cloud Solutions Practice Question
This DOP-C02 practice question tests your understanding of resilient cloud 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 uses DynamoDB global tables for a multi-region application. They notice that write conflicts are occurring. Which TWO strategies can reduce write conflicts?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use conditional writes in the application code
Using conditional writes ensures no overwrites unless condition is met, reducing conflicts. Application-level conflict resolution can handle conflicts when they occur. Option C is wrong because increasing WCU does not reduce conflicts. Option D is wrong because last writer wins is default and may cause data loss. Option E is wrong because reducing read capacity is irrelevant.
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.
✗
Reduce read capacity units to limit concurrent reads
Why it's wrong here
Not relevant to writes.
✗
Enable DynamoDB Streams with last writer wins
Why it's wrong here
Last writer wins is default; may cause data loss.
✓
Use conditional writes in the application code
Why this is correct
Prevents overwriting if condition fails.

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.
