Question

Difficulty: MediumAzure Resources, Resource Groups, Subscriptions, and Management Groups

An administrator is planning the deployment of a new application in Azure. The application requires virtual machines to be deployed in the East US region and a storage account to be deployed in the West US region. The administrator wants to manage all of these resources together as a single logical unit and is considering nesting resource groups to represent different application tiers. Which of the following statements correctly describes how Azure resource groups can be used to meet these requirements?

  1. The administrator can place all resources in a single resource group regardless of their region, but resource groups cannot be nested.Answer
  2. B
    The administrator can nest resource groups to represent the application tiers, and resources can reside in different regions than their resource group.
  3. C
    The administrator cannot nest resource groups, and all resources within a resource group must be deployed in the same region as the resource group.
  4. D
    The administrator can nest resource groups to represent the application tiers, but all resources within a resource group must be deployed in the same region as the resource group.

Answer

The administrator can place all resources in a single resource group regardless of their region, but resource groups cannot be nested.
The statement expressing that resources can be placed in a single resource group regardless of their region, while noting that resource groups cannot be nested, is correct. Azure Resource Groups provide a flat logical container structure that does not support nesting. However, they allow resources from different geographical regions to be grouped together for lifecycle management.

Step-by-Step Solution

1
Evaluate the requirement for nesting resource groups in Azure.
Azure does not support nesting resource groups; a resource group cannot contain another resource group.
This is a fundamental design limitation of Azure Resource Manager (ARM) resources.
2
Evaluate the requirement for deploying resources in different regions within the same resource group.
Resources in a resource group can reside in any Azure region; they do not need to match the resource group's location.
The resource group location is used to store metadata about the resources, not to restrict the deployment region of the resources themselves.
3
Combine these constraints to identify the correct administrative approach.
All application resources (in East US and West US) can be grouped into one resource group, but the tiers cannot be organized using nested resource groups.
This configuration respects both the flat structure of resource groups and the regional flexibility of individual resources.

Key Concept

Azure Resource Group structure, nesting constraints, and resource location independence.
