A developer is troubleshooting an application that uses Amazon DynamoDB. The application sometimes receives ProvisionedThroughputExceededException errors. The table has on-demand capacity mode. The errors occur in short bursts. 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 request rate exceeds the partition's throughput capacity in a short burst.
On-demand capacity mode can handle up to the table's previous peak traffic. However, if traffic spikes suddenly, DynamoDB might throttle. Option D is correct because on-demand has a limit on the maximum throughput per partition. Option A is wrong because indexes share the table's capacity. Option B is wrong because on-demand does not have provisioned limits. Option C is wrong because the table is on-demand, not provisioned.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The table has a low read/write capacity mode limit that needs to be increased.
Why it's wrong here
On-demand automatically scales, but there is a limit per partition.
- ✗
The global secondary index (GSI) has a different throughput limit.
Why it's wrong here
GSIs in on-demand mode share the table's throughput.
- ✗
The table has reached the maximum provisioned throughput.
Why it's wrong here
On-demand tables do not have provisioned throughput.
- ✓
The request rate exceeds the partition's throughput capacity in a short burst.
Why this is correct
On-demand can throttle if a single partition's throughput is exceeded.
