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.
A developer is designing a serverless application using AWS Lambda. The function needs to process messages from an Amazon SQS queue. The developer wants to configure the Lambda function to be triggered by the SQS queue. Which TWO actions are required? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Attach an IAM execution role to Lambda with permission to receive messages from SQS.
B and D are correct. The Lambda function needs an event source mapping (B) and the execution role needs permissions to poll the queue (D). Option A is wrong because SQS does not need a resource-based policy for the same account. Option C is wrong because DLQ is optional. Option E is wrong because VPC is not required.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Configure a resource-based policy on the SQS queue to allow Lambda invocation.
Why it's wrong here
Incorrect: Event source mapping uses the Lambda service principal.
✓
Create an event source mapping in Lambda to poll the SQS queue.
Why this is correct
Correct: This is how Lambda is triggered by SQS.

✗
Set up a dead-letter queue for failed messages.
Why it's wrong here
Incorrect: DLQ is optional, not required.
✗
Place the Lambda function in a VPC to access the SQS queue.
Why it's wrong here
Incorrect: SQS is accessible over the internet without VPC.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
