DBS-C01 Monitoring and Troubleshooting Practice Question
This DBS-C01 practice question tests your understanding of monitoring and troubleshooting. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 auto scaling enabled. Despite auto scaling, the application is still experiencing throttling during traffic spikes. Which THREE actions should the company take to resolve this issue? (Choose THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement exponential backoff in the application code
Options A, D, and E are correct. Enabling DynamoDB Accelerator (DAX) reduces read load. Implementing exponential backoff helps retry gracefully. Using DynamoDB global tables can distribute write load. Option B is wrong because disabling auto scaling would not help. Option C is wrong because switching to on-demand capacity might help but is not always cost-effective and does not address hot keys.
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.
✓
Implement exponential backoff in the application code
Why this is correct
Exponential backoff helps retry throttled requests without overwhelming the system.

Read the scenario before looking for a memorised answer.
✓
Enable DynamoDB Accelerator (DAX) to cache read-heavy workloads
Why this is correct
DAX reduces read load on the table, reducing throttling.

✓
Use DynamoDB global tables to distribute write traffic across regions
Why this is correct
Global tables can spread write load, reducing throttling.

✗
Switch to on-demand capacity mode
Why it's wrong here
On-demand may help but is not one of the three best actions; it also does not address hot keys.
✗
Disable auto scaling and set fixed capacity
Why it's wrong here
Disabling auto scaling would not help; it may worsen the issue.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
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.
