Q233.During a security audit of a Service team's application a Solutions Architect discovers that a username and password for an Amazon RDS database and a set of AWS IAM user credentials can be viewed in the AWS Lambda function code. The Lambda function uses the username and password to run queries on the database and it uses the IAM credentials to call AWS services in a separate management account. The Solutions Architect is concerned that the credentials could grant inappropriate access to anyone who can view the Lambda code.The management account and the Service team's account are in separate AWS Organizations organizational units (OUs). Which combination of changes should the Solutions Architect make to improve the solution's security? (Select TWO.)

B.Configure Lambda to use the stored database credentials in AWS Secrets Manager and enable automatic rotation. C.Create a Lambda function to rotate the credentials every hour by deploying a new Lambda version with the updated credentials : D.Use an SCP on the management account's OU to prevent IAM users from accessing resources in the Service team's account.
