The answer is concurrent writes to the same item in multiple regions. This is the most likely cause of an increasing ReplicatedWriteConflictCount metric because DynamoDB global tables use last-writer-wins reconciliation; when two replicas receive simultaneous updates to the same primary key, the service cannot resolve the conflict automatically, incrementing this counter instead. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your understanding of global table conflict resolution versus throttling or consistency issues—a common trap is confusing write conflicts with ProvisionedThroughputExceeded events or network latency. Remember that conflicts are about *same item, same time, different regions*, not about capacity or speed. A useful memory tip: think of it as a “twin write” problem—if two regions both claim to be the last writer, DynamoDB flags the conflict rather than guessing which one is correct.
DBS-C01 Monitoring and Troubleshooting Practice Question
This DBS-C01 practice question tests your understanding of monitoring and troubleshooting. 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 database specialist is monitoring an Amazon DynamoDB global table with two replicas in separate regions. The specialist notices that the 'ReplicatedWriteConflictCount' metric is increasing. What is the MOST likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The same item is being written concurrently in multiple regions
Option D is correct because concurrent writes to the same item in different regions cause conflicts. Option A is wrong because provisioned throughput affects throttling, not conflicts. Option B is wrong because network latency does not cause conflicts. Option C is wrong because eventual consistency does not cause conflicts.
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.
✗
Insufficient write capacity in one of the regions
Why it's wrong here
Low capacity causes throttling, not conflicts.
✗
High network latency between the regions
Why it's wrong here
Latency affects propagation, not conflicts.
✗
The application is using strongly consistent reads
Why it's wrong here
Strong reads do not cause write conflicts.
✓
The same item is being written concurrently in multiple regions
Why this is correct
Global tables use last-writer-wins; concurrent writes increase conflict count.

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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
