Question 1003Question

An organization is setting up its Azure environment to deploy resources for a new platform. They need to define their resource hierarchy to align with company governance policies. Which of the following organizational designs is valid in Microsoft Azure?

Show answer & explanation

Answer: A subscription is associated with a single management group, and it contains resource groups that can hold resources deployed across different Azure regions.

Answer

A subscription is associated with a single management group, and it contains resource groups that can hold resources deployed across different Azure regions.
The correct design complies with all Azure hierarchical rules. An Azure subscription can only have one parent management group. Resource groups exist within a subscription and can contain resources from any region, meaning a resource does not need to match the location of its resource group.

Step-by-Step Solution

1
Analyze the management group to subscription relationship.
A subscription can belong to only one parent management group at a time, establishing a clear hierarchical structure.
Understanding the hierarchy is essential for correct organizational design.
2
Analyze the resource group and resource relationship.
Resource groups are logical containers within a subscription. Resources inside a resource group do not need to share the same region/location as the resource group itself.
This shows that resource group location is separate from resource location.
3
Evaluate the option choices to identify the valid design.
The design where a subscription belongs to one management group and contains resource groups with resources in different regions is correct and supported in Azure.
It matches Azure's structural and regional independence rules.
