Exam AZ-900 Topic 6 Question 366 Discussion

Section: Describe Core Azure Services
Explanation:
Box 1: No
A resource can interact with resources in other resource groups.
Box 2: Yes
Deleting the resource group will remove the resource group as well as all the resources in that resource group.
This can be useful for the management of resources. For example, a virtual machine has several components (the VM itself, virtual disks, network adapter etc.). By placing the VM in its own resource group, you can delete the VM along with all its associated components by deleting the resource group.
Another example is when creating a test environment. You could place the entire test environment (Network components, virtual machines etc.) in one resource group. You can then delete the entire test environment by deleting the resource group.
Box 3: Yes
Resources from multiple different regions can be placed in a resource group. The resource group only contains metadata about the resources it contains.
