- A
Hardcode the credentials in the application code.
Why wrong: Insecure and not a best practice.
- B
Store credentials in Elastic Beanstalk environment properties.
Why wrong: Properties can be exposed in logs.
- C
Store credentials in an Amazon S3 bucket with public read access.
Why wrong: Public access is insecure.
- D
Store credentials in AWS Secrets Manager and retrieve them at runtime.
Secrets Manager provides secure storage and rotation.

DVA-C02 Deployment Practice Question
This DVA-C02 practice question tests your understanding of deployment. 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 deploying an application using AWS Elastic Beanstalk. The application needs to connect to an Amazon RDS database. What is the best practice for storing database credentials?

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
✓
Store credentials in AWS Secrets Manager and retrieve them at runtime.
Option D is correct because AWS Secrets Manager provides a secure, auditable service for rotating and managing database credentials. By retrieving secrets at runtime via the AWS SDK, the application avoids embedding sensitive data in code or configuration, which is a key security best practice for Elastic Beanstalk deployments.
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
The trap here is that candidates often confuse Elastic Beanstalk environment properties with secure storage, not realizing they are stored in plaintext and accessible via the environment configuration, unlike Secrets Manager which provides encryption and rotation.
Detailed technical explanation
How to think about this question
AWS Secrets Manager integrates with Elastic Beanstalk via the `AWSEBCloudFormation` stack, allowing the application to use the AWS SDK's `GetSecretValue` API call over HTTPS with IAM permissions. Under the hood, Secrets Manager encrypts secrets using AWS KMS, and supports automatic rotation with RDS via a Lambda function, ensuring credentials are rotated without application downtime. A real-world scenario is a multi-tier web app where the database password changes every 30 days; Secrets Manager handles this seamlessly while the app reconnects using the new secret.
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.
TExam Day Tips
- 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.
