A company's developer is building a static website to be deployed in Amazon S3 for a production environment. The website integrates with an Amazon Aurora PostgreSQL
database by using an AWS Lambda function. The website that is deployed to production will use a Lambda alias that points to a specific version of the Lambda function.
The company must rotate the database credentials every 2 weeks. Lambda functions that the company deployed previously must be able to use the most recent credentials.
Which solution will meet these requirements?

  1. Store the database credentials in AWS Secrets Manager. Turn on rotation.
    Write code in the Lambda function to retrieve the credentials from Secrets
    Manager.
  2. Include the database credentials as part of the Lambda function code. Update the credentials periodically and deploy the new Lambda function.
  3. Use Lambda environment variables. Update the environment variables when new credentials are available.
  4. Store the database credentials in AWS Systems Manager Parameter Store. Turn on rotation. Write code in the Lambda function to retrieve the credentials from Systems Manager Parameter Store.

A company must deploy all its Amazon RDS DB instances by using AWS CloudFormation templates as part of AWS CodePipeline continuous integration and continuous delivery
(CI/CD) automation. The primary password for the DB instance must be automatically generated as part of the deployment process.
Which solution will meet these requirements with the LEAST development effort?

  1. Create an AWS Lambda-backed CloudFormation custom resource. Write Lambda code that generates a secure string. Return the value of the secure string as a data field of the custom resource response object. Use the
    CloudFormation Fn::GetAtt intrinsic function to get the value of the secure string. Use the value to create the DB instance.
  2. Use the AWS CodeBuild action of CodePipeline to generate a secure string by using the following AWS CLI command: aws secretsmanager get-random-password.
    Pass the generated secure string as a CloudFormation parameter with the
    NoEcho attribute set to true. Use the parameter reference to create the DB
    instance.
  3. Create an AWS Lambda-backed CloudFormation custom resource. Write Lambda code that generates a secure string. Return the value of the secure string as a data field of the custom resource response object. Use the
    CloudFormation Fn::GetAtt intrinsic function to get a value of the secure string. Create secrets in AWS Secrets Manager. Use the secretsmanager dynamic reference to use the value stored in the secret to create the DB
    instance.
  4. Use the AWS::SecretsManager::Secret resource to generate a secure string.
    Store the secure string as a secret in AWS Secrets Manager. Use the secretsmanager dynamic reference to use the value stored in the secret to create the DB instance.

Answer(s): D
