- A
Use AWS Systems Manager Parameter Store with a SecureString parameter for the password.
Parameter Store with SecureString provides encrypted storage for the password.
- B
Use AWS Secrets Manager to store the master password and reference it dynamically.
Secrets Manager securely stores the password and allows dynamic reference in CloudFormation.
- C
Hardcode the master password in the CloudFormation template.
Why wrong: Hardcoding passwords is insecure and exposes them in the template.
- D
Use IAM database authentication to manage credentials.
Why wrong: IAM database authentication is an alternative to passwords, not a method to store the master password.
- E
Leave the master password empty so that CloudFormation generates a random password.
Why wrong: CloudFormation does not generate a random password; the password must be provided.
Quick Answer
The answer is to use AWS Secrets Manager to store the master password and reference it dynamically within the CloudFormation template. This is correct because secure credential management for RDS requires avoiding hardcoded secrets in templates or parameters, instead leveraging a dedicated secrets service that integrates natively with CloudFormation via dynamic references, such as the `resolve:secretsmanager:` syntax. On the AWS Certified Developer Associate DVA-C02 exam, this concept tests your understanding of infrastructure-as-code security best practices, often appearing in questions that pair CloudFormation with RDS to see if you recognize that both Secrets Manager and Systems Manager Parameter Store are valid, secure options—while IAM database authentication is a separate feature for access control, not credential storage. A common trap is choosing the option that sets a default password, which is insecure because it remains static and visible. Remember the mnemonic "Secrets store, don't hardcode" to recall that dynamic references keep credentials out of your templates.
DVA-C02 Deployment Practice Question
This DVA-C02 practice question tests your understanding of deployment. 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.
A developer is deploying an application using AWS CloudFormation. The stack includes an Amazon RDS DB instance. To ensure secure credential management, which TWO actions should the developer take? (Choose TWO.)
Answer choices
Why each option matters
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 with a SecureString parameter for the password.
Options B and D are correct. Using AWS Secrets Manager or Systems Manager Parameter Store to store database credentials securely is a best practice. Option A is incorrect because hardcoding credentials in the template is insecure. Option C is incorrect because the default password is not automatically randomized; it must be explicitly set. Option E is incorrect because IAM database authentication is separate from credential storage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
