The solution must also include the ability to generate a report to easily track and manage coverage. The company has a policy that allows only one workload for each AWS account.Which set of steps should the solutions architect take to create the report and alert the DevOps team?
A.Create an Amazon Simple Notification Service (Amazon SNS) topic and subscribe the DevOps email distribution list. Enable cost allocation tags and ensure instances populate a customer-managed cost allocation tag at startup. Use the AWS Billing and Cost Management console to create a budget for RI正确答案A
