This DVA-C02 practice question tests your understanding of development with aws services. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Refer to the exhibit. A developer invoked a Lambda function and received the response shown. What does the response indicate?
The function was not invoked due to a permissions error.
Why wrong: A permissions error would return a 403.
The function executed successfully but did not return any logs.
Why wrong: Successful execution would not have FunctionError set.
The invocation timed out.
Why wrong: A timeout would return a 200 with a different error.
The function was invoked but returned an error.
FunctionError indicates an unhandled error in the function.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The function was invoked but returned an error.
The response includes a 'FunctionError' field with value 'Unhandled' and an 'error' object, indicating that the Lambda function was invoked successfully (StatusCode 200) but the function itself encountered an error during execution. Option A is incorrect because a permissions error would result in a 4xx or 5xx StatusCode, not 200. Option B is incorrect because the function did not execute successfully—it returned an error. Option C is incorrect because a timeout would typically produce a 'null' FunctionError or a specific timeout error, not an explicit error object. Option D is correct: the function was invoked, but it returned an error.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
The function was not invoked due to a permissions error.
Why it's wrong here
A permissions error would return a 403.
The function executed successfully but did not return any logs.
Why it's wrong here
Successful execution would not have FunctionError set.
The invocation timed out.
Why it's wrong here
A timeout would return a 200 with a different error.
The function was invoked but returned an error.
Why this is correct
FunctionError indicates an unhandled error in the function.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Refer to the exhibit. A developer invokes a Lambda function using the AWS CLI. The response shows StatusCode 200 and FunctionError: Unhandled. What does this indicate?
easyWhy A: A is correct because a StatusCode 200 from an AWS Lambda invocation via the AWS CLI indicates that the invocation request itself was accepted and processed by the Lambda service, but the presence of FunctionError: Unhandled means the function code threw an exception that was not caught by any try-catch block or error handler. This results in the Lambda service returning a 200 HTTP status for the invocation request while signaling the error via the FunctionError field in the response payload.
