DVA-C02 Development with AWS Services Practice Question
This DVA-C02 practice question tests your understanding of development with aws services. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Exhibit
Error: Function 'my-function' timed out after 3 seconds
Refer to the exhibit. A developer invokes an AWS Lambda function and receives this error. The function is configured with a 3-second timeout. The developer needs to process data that sometimes takes up to 10 seconds. What should the developer do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the Lambda function timeout to 10 seconds.
Option D is correct because increasing the timeout to 10 seconds allows the function to complete. Option A is incorrect because increasing memory does not directly affect timeout. Option B is incorrect because async invocation does not change timeout. Option C is incorrect because reserved concurrency does not affect timeout.
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.
✗
Change the invocation type to Event (async).
Why it's wrong here
Async invocation still has a timeout.
✓
Increase the Lambda function timeout to 10 seconds.
Why this is correct
Increasing timeout allows longer execution.
Related concept
Read the scenario before looking for a memorised answer.
✗
Increase the memory allocation for the Lambda function.
Why it's wrong here
More memory may speed up execution but does not change the timeout limit.
✗
Set reserved concurrency to 1.
Why it's wrong here
Reserved concurrency does not affect timeout.
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.
