Tutorial / Cram Notes
A resource group is a container that holds related resources for an Azure solution. The resources in a resource group could include virtual machines, storage accounts, virtual networks, web apps, databases, and more. Typically, resources are grouped based on lifecycle and managed as a single entity; for example, resources for an application may be grouped together so they can be easily deployed, updated, or deleted.
Creating Resource Groups
To create a resource group, follow these steps:
- Open Azure Portal.
- Navigate to “Resource groups” from the menu or use the search bar.
- Click on “Add” or “+ Create”.
- Fill in the Resource group name, Subscription, and the Region where you want the resources to reside.
- Click “Review + create” and then “Create”.
You can also create resource groups using Azure CLI, PowerShell, or Templates.
Example with Azure PowerShell:
New-AzResourceGroup -Name ‘ExampleResourceGroup’ -Location ‘EastUS’
Managing Resources in a Resource Group
Once a resource group is created, you can manage the resources within it.
- Adding Resources: You can add resources while creating them by specifying the resource group, or you can move some resources between groups although limitations and conditions may apply.
- Access Control (IAM): Assign roles to users or groups to manage access to the resources within the group.
- Tagging: Apply tags to resources for logical organization that transcends resource groups or to include in the resource group’s metadata.
- Locks: Apply locks to prevent accidental deletion or modification of critical resources.
- Policies: Apply policies at the resource group level to enforce standards and compliance.
Moving Resources Between Resource Groups
You can move resources from one resource group to another. However, not all resources can be moved, and some may require special considerations.
To move resources, select the resources within an Azure resource group, click on the “Move” button, choose “Move to another resource group,” and then select the target group. Azure will validate the move before it takes place to ensure that it’s supported for the selected resources.
Deleting Resource Groups
When a resource group is no longer needed, you can delete it. Deleting a resource group also deletes all the resources contained within it. Ensure there are no critical resources that need to be retained or moved before you delete a resource group.
To delete a resource group:
- Navigate to the “Resource groups” section in the Azure Portal.
- Select the resource group you wish to remove.
- Click on “Delete resource group” at the top of the resource group’s overview window.
- You will be prompted to enter the name of the resource group to confirm the deletion.
Automating Resource Group Management
Resource group deployment can be automated using Azure Resource Manager (ARM) Templates. These templates are JSON files that define the resources and configurations for deployment.
Example ARM Template snippet:
{
“$schema”: “https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#”,
“contentVersion”: “1.0.0.0”,
“resources”: [
{
“type”: “Microsoft.Resources/resourceGroups”,
“apiVersion”: “2020-06-01”,
“location”: “WestUS”,
“name”: “ExampleResourceGroup”,
“properties”: {}
}
]
}
An Azure Administrator must comprehend resource group scope and lifecycle to manage Azure resources effectively. Understanding these concepts allows for more effective governance, cost management, and simplification of resource management tasks. By mastering resource groups, you not only streamline your Azure infrastructure but also assure that you meet one of the necessary competencies for the AZ-104 exam.
Practice Test with Explanation
True or False: Resource groups in Azure can be nested.
- True
- False
Answer: False
Explanation: Resource groups in Azure cannot be nested. A resource group can contain resources, but it cannot contain other resource groups.
True or False: Once a resource group is created in a specific Azure region, it can be moved to a different region.
- True
- False
Answer: False
Explanation: The resource group’s region is for management purposes. The actual location of the resources can be different and independent of the resource group’s region.
Which of the following can be done with an Azure resource group? (Select all that apply)
- Applying policies to resources within the group
- Billing consolidation for all resources within the group
- Replicating resources in different regions
- Assigning role-based access control (RBAC) to the group
Answer: Applying policies to resources within the group, Billing consolidation for all resources within the group, Assigning role-based access control (RBAC) to the group
Explanation: Azure resource groups allow for applying policies, consolidating billing, and assigning RBAC to manage and secure resources effectively.
True or False: A resource can exist outside of a resource group in Azure.
- True
- False
Answer: False
Explanation: In Azure, every resource must be associated with a resource group.
Which Azure service is used to manage resource groups and resources at scale?
- Azure Policy
- Azure Resource Manager
- Azure Service Fabric
- Azure Functions
Answer: Azure Resource Manager
Explanation: Azure Resource Manager is the service used to deploy, manage, and organize resources and resource groups in Azure.
True or False: Deleting a resource group will also delete all the resources contained within it.
- True
- False
Answer: True
Explanation: Deleting a resource group includes deleting all resources within that resource group. This action cannot be undone.
When moving resources from one resource group to another, which of the following must remain the same?
- Resource type
- Resource location
- Subscription
- Both resource type and location
Answer: Both resource type and location
Explanation: While moving resources, the destination resource group must be in the same subscription, and resources must be moved to a resource group in the same region.
True or False: You can apply tags to a resource group to organize resources across different resource groups and subscriptions.
- True
- False
Answer: True
Explanation: Tags can be applied to resource groups and resources to provide metadata and help with the organization of Azure resources.
Which of the following statements about Azure Resource Manager (ARM) templates is correct?
- ARM templates can only be used within a single subscription.
- ARM templates can only deploy resources in the same region as the resource group.
- ARM templates support the deployment of resources into multiple resource groups.
- ARM templates can only create one resource at a time.
Answer: ARM templates support the deployment of resources into multiple resource groups.
Explanation: ARM templates can be used to deploy complex environments including resources that span multiple resource groups and subscriptions, provided that the user has the appropriate permissions.
True or False: You must manually remove dependencies between resources before deleting a resource group.
- True
- False
Answer: False
Explanation: Azure takes care of automatically deleting the resources within a resource group, maintaining the correct order to respect dependencies among resources.
What is the primary benefit of using resource groups in Azure?
- To increase the performance of resources within the group
- To logically organize resources for better management
- To reduce the cost of resources within the group
- To enhance the security of resources by isolating them from the rest of the network
Answer: To logically organize resources for better management
Explanation: The primary benefit of using resource groups is to organize and manage related resources in a logical way, which can aid in access control, billing, and management policies.
True or False: It is possible to convert an existing resource from one resource type to another by moving it between resource groups.
- True
- False
Answer: False
Explanation: Moving resources between resource groups does not change the resource type. The type of a resource is fixed upon its creation and cannot be converted into another type through resource group movement.
