The Register-AzureRmAutomationDscNode cmdlet registers an Azure virtual machine as an APS Desired State Configuration (DSC) node in an Azure Automation account.
Scenario: The Azure DevOps organization includes:
The Docker extension
A deployment pool named Pool7 that contains10 Azure virtual machines that run Windows Server 2016

Topic 1, Contoso Case Study: 2
Overview
Existing Environment
Contoso, Ltd. is a manufacturing company that has a main office in Chicago.
Requirements
Contoso plans to improve itsIT development and operations processes implementing Azue DevOps principles.
Contoso has an Azure subscription and creates an Azure DevelPs organization.
The Azure DevOps organization includes:
The Docker extension
A deployment pool named Pool7 that contains 10 Azure virtual machines that run Windows Server 2016.
The Azure subscription contains an Azure Automation account.
Planned Changes
Contoso plans to create projects in Azure DevOps as shown in the following table.

Technical Requirements
Contosoidentities the following technical requirements:
* Implement build agents rot Project 1.
* Whenever possible, use Azure resources
*Avoid using deprecated technologies
* Implement a code flow strategy for Project2 that will:
*Enable Team 2 to submit pull requests for Project2.
* Enable Team 2 to work independently on changes to a copy of Project?
* Ensure that any intermediary changes performed by Tram2 on a copy of Project2 will be subject to the same restrictions as the ones defied in the build policy of Project2.
* Whenever possible. Implement automation and minimize administrative effort.
* Implement Protect3, Project5, Project6, and Project7 based on the planned changes.
* Implement Project4 and configure the project to push Docker images to Azure Container Reentry.

You can use the combination of Terraform and Yeoman. Terraform is a tool for creating infrastructure on Azure. Yeoman makes it easy to create Terraform modules.
Terratest provides a collection of helper functions and patterns for common infrastructure testing tasks, like making HTTP requests and using SSH to access a specific virtual machine. The following list describes some of the major advantages of using Terratest:
* Convenient helpers to check infrastructure - This feature is useful when you want to verify your real infrastructure in the real environment.
* Organized folder structure - Your test cases are organized clearly and follow the standard Terraform module folder structure.
* Test cases are written in Go - Many developers who use Terraform are Go developers. If you're a Go developer, you don't have to learn another programming language to use Terratest.
* Extensible infrastructure - You can extend additional functions on top of Terratest, including Azure-specific features.

A: You can use Azure Monitor to monitor base-level metrics and logs for most services in Azure. You can call Azure Automation runbooks by using action groups or by using classic alerts to automate tasks based on alerts.
B: Metric Alert with Dynamic Thresholds detection leverages advanced machine learning (ML) to learn metrics' historical behavior, identify patterns and anomalies that indicate possible service issues. It provides support of both a simple UI and operations at scale by allowing users to configure alert rules through the Azure Resource Manager API, in a fully automated manner.
