DBS-C01 Monitoring and Troubleshooting Practice Question
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?
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
✓
The same item is being written concurrently in multiple regions
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.
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.
