Final answer:
Azure resources in a resource group can be located in different Azure regions; a resource group is a logical container, not restricted by regions.
Step-by-step explanation:
The student asked whether all the Azure resources deployed to a resource group must use the same Azure region or different Azure regions. The answer is that resources within an Azure resource group do not need to be located in the same Azure region. A resource group is simply a logical container that groups related resources for an Azure solution. The resources can exist in multiple regions, which allows for the organization and management of resources that span geographic locations.
