DVA-C02 Development with AWS Services Practice Question
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?
⚠ Common exam trap
Watch out — 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.

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.
