This DVA-C02 practice question tests your understanding of security. 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 company uses AWS Secrets Manager to store database credentials. The application runs on Amazon EC2 instances with an IAM role attached. How should the application retrieve the secret securely?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Store the secret ID in an environment variable and use the AWS SDK to retrieve it
The best practice is to use the IAM role to call Secrets Manager APIs. The role must have a policy allowing secretsmanager:GetSecretValue. The application can then retrieve the secret at runtime using the AWS SDK.
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.
✗
Use AWS Systems Manager Parameter Store with a secure string parameter
Why it's wrong here
Parameter Store can be used, but Secrets Manager is specifically designed for secrets and offers automatic rotation.
✓
Store the secret ID in an environment variable and use the AWS SDK to retrieve it
Why this is correct
Using the IAM role, the application can call Secrets Manager with the secret ID stored in an environment variable.

✗
Store the secret in an S3 bucket with server-side encryption
Why it's wrong here
Secrets Manager provides better access control and rotation; S3 is not designed for secrets.
✗
Hardcode the secret in the application code
Why it's wrong here
Hardcoding secrets is insecure and violates best practices.

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.
