Manage ECS Secrets with AWS Secrets Manager | AWS Developer Associate Explained
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 developer is deploying a containerized application on Amazon ECS using Fargate. The application needs to store sensitive configuration data, including database passwords, that must be rotated regularly. Which service should the developer use to manage these secrets securely?
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
✓
AWS Secrets Manager
AWS Secrets Manager is the correct choice because it is purpose-built for securely storing, retrieving, and automatically rotating sensitive configuration data such as database passwords. It integrates natively with Amazon ECS (via the `secrets` container definition parameter) and supports automatic rotation using AWS Lambda, which meets the requirement for regular rotation without custom code.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Amazon S3 with server-side encryption
Why it's wrong here
S3 can store encrypted data but requires custom rotation logic.
- ✓
AWS Secrets Manager
Why this is correct
Secrets Manager provides automatic secret rotation and fine-grained access control.

- ✗
Amazon DynamoDB with server-side encryption
Why it's wrong here
DynamoDB is a database, not designed for secret management.
- ✗
AWS Systems Manager Parameter Store
Why it's wrong here
Parameter Store can store secrets but lacks automatic rotation.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS Systems Manager Parameter Store (which can store secrets but lacks native rotation) with AWS Secrets Manager, overlooking the explicit requirement for 'regular rotation' in the question.
Detailed technical explanation
How to think about this question
AWS Secrets Manager uses envelope encryption with AWS KMS, where a data key encrypts the secret and the data key itself is encrypted by a customer master key (CMK). When rotation is enabled, Secrets Manager invokes a Lambda function that updates the secret in both the service and the target database (e.g., RDS), ensuring zero-downtime rotation by maintaining previous versions for a configurable window. This is governed by the `RotateSecret` API and the `SecretsManagerRotationTemplate` CloudFormation resource.
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.
