DVA-C02 Development with AWS Services Practice Question
This DVA-C02 practice question tests your understanding of development with aws services. 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 developer is debugging a Lambda function that is triggered by an S3 event. The function is supposed to process images and store metadata in DynamoDB. However, the function times out after 3 seconds for large images. The function's timeout is currently set to 5 seconds. What should the developer do to resolve the issue without increasing the timeout?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use multipart upload or stream processing to handle the image in chunks.
Correct: B. The function times out because it processes the image synchronously. By using S3 Multipart upload or processing in chunks, the function can handle large images faster. Option A is wrong because increasing memory may help but does not address the timeout issue directly. Option C is wrong because increasing timeout is not allowed per the condition. Option D is wrong because SQS does not speed up processing.
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.
✗
Increase the Lambda function's memory allocation to improve performance.
Why it's wrong here
Increasing memory may improve performance but might not resolve the timeout for very large images.
✗
Increase the Lambda function's timeout to 15 minutes.
Why it's wrong here
The condition says without increasing the timeout.
✓
Use multipart upload or stream processing to handle the image in chunks.
Why this is correct
Streaming or chunking can reduce memory usage and processing time.
Related concept
Read the scenario before looking for a memorised answer.
✗
Offload the processing to an Amazon SQS queue and process asynchronously.
Why it's wrong here
SQS does not speed up the processing per se; it adds complexity.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
