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 AppConfig, a feature of AWS Systems Manager.
(AWS AppConfig, a feature of AWS Systems Manager) and Option E (AWS Systems Manager Parameter Store) are both purpose-built services for storing and retrieving configuration at runtime. AppConfig provides validation, deployment strategies, and rollback capabilities, making it ideal for managing application configuration in a controlled manner. Parameter Store offers secure, hierarchical storage for configuration data and integrates seamlessly with AWS services. Option A (S3) is general object storage, not optimized for runtime configuration retrieval with validation. Option B (Secrets Manager) is designed for managing secrets, not general configuration. Option C (DynamoDB) is a NoSQL database; while it can store configuration, it lacks the deployment controls and native integration of AppConfig and Parameter Store.
