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

An administrator is planning the deployment of a new web application in Azure that requires web servers in East US and databases in West US. The administrator wants to use resource groups to organize these resources. Which two statements regarding Azure resources and resource groups are correct?

  1. A resource group can contain resources that reside in different Azure regions.Answer
  2. An Azure resource can belong to only one resource group at a time.Answer
  3. C
    Resource groups can be nested within other resource groups to establish a hierarchy.
  4. D
    Resources deployed inside a resource group are restricted to the same Azure region as the resource group.

Answer

A resource group can contain resources that reside in different Azure regions, and an Azure resource can belong to only one resource group at a time.
The correct options are that a resource group can contain resources residing in different regions, and a resource can belong to only one resource group. The location of a resource group is used to store metadata about the resources, and it has no impact on the physical regions of the resources inside. Furthermore, every Azure resource must belong to exactly one resource group.

Step-by-Step Solution

1
Analyze the relationship between Azure resources and resource groups regarding regional placement.
Confirm that a resource group's location is only for its metadata, allowing resources within it to be placed in any Azure region.
This determines if resources must match the resource group's location.
2
Analyze resource membership rules within resource groups.
Confirm that a resource cannot belong to multiple resource groups simultaneously, though it can be moved between them.
This determines the membership limits of a resource.
3
Verify if resource groups support hierarchical nesting.
Confirm that resource groups cannot be nested inside each other.
This rules out the possibility of hierarchical resource group structures.
