Deploying a template in Azure is a pivotal skill for anyone preparing for the AZ-104 Microsoft Azure Administrator exam. Templates, typically in the form of Azure Resource Manager (ARM) templates, are a powerful way to define and deploy your infrastructure as code, which ensures consistency, repeatability and can help streamline the deployment of resources.
An ARM template is a JSON (JavaScript Object Notation) file that defines the infrastructure and configuration for your project. The template uses declarative syntax to let you define deployment properties, which Azure then uses to provision the resources.
An ARM template is made up of the following components:
{
“$schema”: “https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#”,
“contentVersion”: “1.0.0.0”,
“parameters”: {
// Parameter definitions
},
“variables”: {
// Variable definitions
},
“resources”: [
// Resource definitions
],
“outputs”: {
// Output definitions
}
}
Deployment of an ARM template can be done using several methods, including Azure Portal, Azure CLI, PowerShell, and Azure Resource Manager API.
az group create –name MyResourceGroup –location eastus
az deployment group create –resource-group MyResourceGroup –template-file /path/to/template.json –parameters /path/to/parameters.json
New-AzResourceGroup -Name MyResourceGroup -Location “East US”
New-AzResourceGroupDeployment -ResourceGroupName MyResourceGroup -TemplateFile /path/to/template.json -TemplateParameterFile /path/to/parameters.json
az deployment group validate
or Test-AzResourceGroupDeployment
in PowerShell.Command | Azure CLI | PowerShell |
---|---|---|
Validate | az deployment group validate | Test-AzResourceGroupDeployment |
Deploy | az deployment group create | New-AzResourceGroupDeployment |
By learning and practicing template deployments, candidates preparing for the AZ-104 Azure Administrator exam will be able to efficiently manage Azure resources, driving automation and consistency in their infrastructure setups.
Answer: A) True
Explanation: Azure Resource Manager templates are indeed JSON files that define the infrastructure and configuration for your project.
Answer: A) Azure Resource Manager
Explanation: Azure Resource Manager is the service that allows you to deploy and manage resources using templates.
Answer: B) False
Explanation: When you deploy a template with Azure Resource Manager, you can specify different regions for deploying resources.
Answer: D) All of the above
Explanation: ARM templates can specify resources, variables, and parameters to create a customizable and repeatable deployment process.
Answer: A) True
Explanation: Both Azure PowerShell and Azure CLI can be used to deploy Azure Resource Manager templates.
Answer: B) To define the schema version being used
Explanation: The ‘$schema’ property in an ARM template specifies the schema to use for validation.
Answer: B) False
Explanation: You do not always have to create a new storage account for your ARM templates; you can use existing storage accounts or other methods like GitHub or Azure DevOps repositories.
Answer: B) Validate the template
Explanation: Validating the ARM template before deployment can help find any errors that would cause the deployment to fail.
Answer: B) az deployment group create
Explanation: The `az deployment group create` command is used to start a deployment at the resource group level using an ARM template.
Answer: A) True
Explanation: When using linked templates, the linked template must be accessible via a public URL. Alternatively, a SAS token can be used if the templates are stored in a private location such as in an Azure Storage Account.
Answer: A) Outputs
Explanation: The Outputs section in an ARM template allows you to retrieve values after the deployment has been completed, like connection strings or IP addresses.
An Azure Resource Manager template is a JSON file that defines the infrastructure and configuration of your Azure resources.
Azure Resource Manager templates provide a declarative way to define the infrastructure and configuration of your Azure resources. Templates can be stored in source control, shared with others, and used to deploy resources repeatedly in different environments. Templates enable you to automate the deployment of resources and ensure consistency across environments.
You can create an Azure Resource Manager template using any text editor, such as Visual Studio Code. Alternatively, you can use the Azure Portal to create a template from an existing resource group.
An Azure Resource Manager template is written in JSON (JavaScript Object Notation) syntax.
Yes, you can include comments in an Azure Resource Manager template by using “//” to start a single-line comment or “/* */” to enclose a multi-line comment.
Yes, you can use variables in an Azure Resource Manager template to simplify the template and make it more readable.
Yes, you can reference resources from other resource groups or subscriptions in an Azure Resource Manager template by using their fully qualified resource IDs.
Yes, you can specify dependencies between resources in an Azure Resource Manager template by using the “dependsOn” property.
Yes, you can deploy an Azure Resource Manager template from the Azure Portal by selecting “Template Deployment” from the list of available resources.
Yes, you can use an existing template from the Azure Quickstart Templates gallery by selecting “Template Deployment” from the list of available resources and selecting the “Quickstart Templates” tab.
Yes, you can use a template from an external URL by selecting “Template Deployment” from the list of available resources and selecting the “Build your own template in the editor” tab.
You can review your deployment settings before deploying an Azure Resource Manager template by selecting the “Review + create” tab on the “Basics” page.
The time required for deployment depends on the size of the template and the number of resources being deployed.
Yes, you can view your deployed resources in the Azure Portal by selecting the resource group where the resources were deployed.
Yes, you can edit or delete resources that were deployed using an Azure Resource Manager template by modifying the template and deploying the changes.
