Explanation: You can use the AWS Config console, AWS CLI, and AWS Config API to look up the resources that AWS Config has taken an inventory of, or discovered, including deleted resources and resources that AWS Config is not currently recording. AWS Config discovers supported resource types only. You can use the AWS Config console in the AWS Management console to look up these resources. The Resource Inventory page lets you perform this search.
