Correct answer & explanation
✓
Set the parameter 'require_secure_transport' to ON and use the AWSAuthenticationPlugin.
IAM database authentication requires a specific parameter group setting (require_secure_transport=ON) and authentication plugin. Option A is wrong because native MySQL authentication is not IAM. Option B is wrong because IAM roles for RDS are for API access, not database authentication. Option C is wrong because the standard MySQL port is 3306.
