DBS-C01 Monitoring and Troubleshooting Practice Question
A company is using Amazon DynamoDB with a global table in two regions. The application is experiencing high write latency on the replica table in the secondary region. Which THREE factors could contribute to this issue?
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
✓
Large item sizes being written to the table.
Global tables replicate writes asynchronously. Large item sizes (A) increase the time to process each write. Network latency (B) between regions affects the replication time. Insufficient write capacity (E) on the replica table can cause throttling and increased latency. Auto scaling configuration (C) is not a direct cause; it helps manage capacity. Read capacity (D) does not affect write latency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Large item sizes being written to the table.
Why this is correct
Larger items take longer to replicate.
- ✓
Network latency between the primary and secondary regions.
Why this is correct
Higher network latency increases replication delay.
- ✗
Auto scaling configuration on the replica table.
Why it's wrong here
Auto scaling adjusts capacity but is not a direct cause of latency; it may help, but not contribute to the issue.
- ✗
Low read capacity on the replica table.
Why it's wrong here
Read capacity does not affect write latency.
- ✓
Insufficient write capacity on the replica table.
Why this is correct
If the replica table's write capacity is throttled, replication writes will be delayed.
