The correct answer is to implement retry logic with exponential backoff, use DynamoDB Accelerator (DAX), and design the application to handle throttling by retrying. These three actions directly address the root cause of throttling in on-demand capacity mode, where traffic spikes can exceed the table’s per-partition throughput limits. Retry logic with exponential backoff allows the application to gracefully recover from temporary throttling, while DAX offloads read-heavy workloads from the primary table, reducing read throttling. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your understanding that on-demand mode does not support auto scaling, and switching to provisioned capacity is not a guaranteed fix—it simply shifts the throttling risk to a different billing model. A common trap is assuming auto scaling applies to on-demand, but it does not; instead, focus on client-side resilience and caching. Memory tip: “Retry, Cache, and Design” — the three pillars to reduce DynamoDB throttling.
DBS-C01 Management and Operations Practice Question
This DBS-C01 practice question tests your understanding of management and operations. 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 company is using Amazon DynamoDB with on-demand capacity mode. The application experiences occasional throttling during traffic spikes. The database administrator wants to implement a solution to reduce throttling. Which THREE actions should the administrator take? (Choose THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use DynamoDB Accelerator (DAX) to cache frequently accessed items.
Options A, C, and D are correct. Implementing retry logic with exponential backoff handles throttling gracefully. Using DynamoDB Accelerator (DAX) reduces read load on the table, which can help with read throttling. Designing the application to handle throttling by retrying ensures resilience. Option B is incorrect because switching to provisioned capacity may not be cost-effective and does not inherently reduce throttling. Option E is incorrect because enabling auto scaling is not applicable to on-demand mode.
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.
✓
Use DynamoDB Accelerator (DAX) to cache frequently accessed items.
Why this is correct
DAX reduces read traffic to the table, decreasing the chance of read throttling.
Related concept
Read the scenario before looking for a memorised answer.
✗
Enable auto scaling for the table.
Why it's wrong here
Auto scaling is for provisioned capacity mode, not on-demand.
✗
Switch the table to provisioned capacity mode with auto scaling.
Why it's wrong here
On-demand mode is designed for spiky traffic; switching to provisioned may increase costs and complexity.
✓
Implement exponential backoff and retry logic in the application.
Read the scenario before looking for a memorised answer.
✓
Design the application to handle throttling by retrying with backoff.
Why this is correct
Building retry logic into the application is a best practice for handling throttling.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
