Amazon Web Services DVA-C02 Exam With Confidence Using Practice Dumps

Why Option C is Correct:Amazon Verified Permissions provides fine-grained access control capabilities, making it ideal for managing complex user permissions. It integrates with OIDC IdPs for authentication and allows applications to request authorization decisions dynamically. It is also easily adaptable to newer applications.

Why Other Options are Incorrect:

Option A: Cognito identity pools do not natively support fine-grained permission analysis or management.

Option B: Managing permissions in application logic adds significant operational overhead.

Option D: IAM roles are not designed for application-specific fine-grained access control and are more suitable for resource-level permissions.

Amazon Verified Permissions

This solution meets the requirements because it uses a PostgreSQL-compatible database that can secure and regularly rotate database credentials without requiring additional programming overhead. Amazon Aurora PostgreSQL is a relational database service that is compatible with PostgreSQL and offers high performance, availability, and scalability. AWS Secrets Manager is a service that helps you protect secrets needed to access your applications, services, and IT resources. You can store database credentials in AWS Secrets Manager and use them to access your Aurora PostgreSQL database. You can also enable automatic rotation of your secrets according to a schedule or an event. AWS Secrets Manager handles the complexity of rotating secrets for you, such as generating new passwords and updating your database with the new credentials. Using Amazon DynamoDB for the database will not meet the requirements because it is a NoSQL database that is not compatible with PostgreSQL. Using AWS Systems Manager Parameter Store for storing and rotating database credentials will require additional programming overhead to integrate with your database.

AWS CodeBuild integrates natively with AWS Secrets Manager , allowing secrets to be securely injected into build environments without being exposed in logs. When referenced using the secrets-manager mapping in the env section of buildspec.yml, CodeBuild automatically retrieves and decrypts the secret at runtime.

AWS documentation states that Secrets Manager provides encryption at rest using AWS KMS, fine-grained IAM access control, and automatic rotation support. Secrets retrieved this way are masked in build logs by default, satisfying the requirement that secrets do not appear in logs.

Parameter Store (Option C) can store encrypted values, but Secrets Manager is AWS’s preferred service for managing secrets, especially when rotation and auditing are required. Options B and D introduce unnecessary steps and higher operational overhead.

Therefore, Secrets Manager with CodeBuild environment variables is the most secure and operationally efficient solution.
