Final answer:
Resource groups cannot be nested; a resource group cannot contain another resource group. Instead, resources can be categorized across different resource groups using tagging or other non-nesting organizational methods.
Step-by-step explanation:
The question 'Can resource groups be nested?' refers to the organization of resources within a cloud computing environment, specifically within the context of resource management. In such systems, resource groups are a way to consolidate and manage related resources for easy administration and billing. It is essential in cloud computing to categorize and control access to resources to ensure efficient resource usage and security.
Resource groups cannot be nested. This means that you cannot create a resource group within another resource group. Each resource must belong to one and only one resource group at any given time. However, you can organize resources using other mechanisms such as tagging, which allows for the categorization of resources across different resource groups without nesting.
