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 using AWS Secrets Manager to rotate database credentials. The rotation Lambda function fails with an error. Which THREE steps should the developer take to troubleshoot? (Choose THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Verify that the Lambda function has network access to the database.
Options A, B, and D are correct. CloudWatch Logs shows error details; IAM permissions are often the cause; network connectivity is required for Lambda to reach the database. Option C is wrong because KMS key rotation is not related. Option E is wrong because VPC flow logs show network traffic but not Lambda errors.
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.
✗
Check VPC Flow Logs for the Lambda function's ENI.
Why it's wrong here
Flow logs show network traffic, not application errors.
✓
Verify that the Lambda function has network access to the database.
Why this is correct
If the database is in a VPC, Lambda needs VPC access.

✗
Ensure the KMS key used to encrypt the secret is rotated.
Why it's wrong here
KMS key rotation is not related to rotation function failures.
✓
Verify that the Lambda function's IAM role has permission to update the secret.
Why this is correct
Secrets Manager requires specific permissions.

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.
