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 company is developing a microservices architecture using Amazon ECS with Fargate launch type. Each microservice needs to store sensitive configuration data such as database passwords. The company wants to avoid storing secrets in the application code or environment variables. What is the MOST secure and recommended approach?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Systems Manager Parameter Store or AWS Secrets Manager to store and retrieve secrets.
Option C is correct because AWS Systems Manager Parameter Store (or Secrets Manager) is designed for secure storage of secrets and can be accessed via IAM roles. Option A is wrong because environment variables can be exposed. Option B is wrong because S3 is not designed for secrets and requires encryption management. Option D is wrong because Lambda is a compute service, not a secret store.
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.
✗
Pass secrets as environment variables in the task definition.
Why it's wrong here
Incorrect: Environment variables might be visible in logs or task definition.
✗
Store secrets in an encrypted S3 bucket and have the application download them at startup.
Why it's wrong here
Incorrect: S3 adds complexity and potential exposure.
✓
Use AWS Systems Manager Parameter Store or AWS Secrets Manager to store and retrieve secrets.
Why this is correct
Correct: These services are built for secure secret management.

✗
Use an AWS Lambda function to generate secrets and store them in DynamoDB.
Why it's wrong here
Incorrect: Unnecessary complexity; DynamoDB is not a secret store.
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.
