DBS-C01 Management and Operations Practice Question
A company is using Amazon DynamoDB with on-demand capacity. The application performs many small writes that are throttled frequently. The company wants to minimize costs while reducing throttling. What should the company do?
⚠ Common exam trap
Watch out — candidates often assume on-demand capacity automatically handles all traffic patterns without throttling, but on-demand throttles when traffic exceeds the table's previous peak, and they may overlook that switching to provisioned capacity with auto scaling provides a cost-effective solution for predictable workloads with frequent small writes.

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
✓
Switch to provisioned capacity with auto scaling.
DynamoDB on-demand capacity can throttle small writes if the traffic pattern exceeds the table's previous peak traffic, as on-demand capacity scales based on traffic volume but has a per-second burst limit. Switching to provisioned capacity with auto scaling allows you to set a baseline capacity that matches the application's average write throughput, while auto scaling adjusts capacity based on actual usage, reducing throttling without the premium cost of on-demand capacity for predictable workloads.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the write capacity units manually.
Why it's wrong here
Manual adjustment is not dynamic and may not minimize costs.
- ✗
Use DynamoDB Accelerator (DAX) to cache writes.
Why it's wrong here
DAX caches reads, not writes.
- ✓
Switch to provisioned capacity with auto scaling.
Why this is correct
Provisioned with auto scaling can handle predictable patterns and reduce cost vs. on-demand.
- ✗
Use batch writes to combine small writes.
Why it's wrong here
Batch writes may help but not directly address throttling for individual small writes.
