Explanation:
You apply tags to your Azure resources to logically organize them into a taxonomy. Each tag consists of a name and a value pair. After you apply tags, you can retrieve all the resources in your subscription with that tag name and value.
Tags enable you to retrieve related resources from different resource groups.
This approach is helpful when you need to organize resources for billing or management.
