Question 1

You plan to create a project in Azure DevOps. Multiple developers will work on the project. The developers will work offline frequentlyand will require access to the full project history while they are offline.

Which version control solution should you use?

ATortotseSVN

BTeam Foundation Version Control

CSubversion

DGit

Answer : D

Git history: File history is replicated on the client dev machine and can be viewed even when not connected to the server. You can view history in Visual Studio and on the web portal.

Note: Azure Repos supports two types of version control: Git and Team Foundation Version Control (TFVC).

Question 4

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.

After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

You have an Azure DevOps project.

Your build process creates several artifacts.

You need to deploy the artifacts to on-premises servers.

Solution: You deploy an Octopus Deploy server. You deploy a polled Tentacle agent to an on-premises server. You add an Octopus task to the deployment pipeline.

Does this meet the goal?

AYes

BNo

Answer : B

Instead you should deploy an Azure self-hosted agent to an on-premises server.

Note: To build your code or deploy your software using Azure Pipelines, you need at least one agent.

If your on-premises environments do nothave connectivity to a Microsoft-hosted agent pool (which is typically the case due to intermediate firewalls), you'll need to manually configure a self-hosted agent on on-premises computer(s).

Question 6

Your company builds a multi tier web application.

>Youuse Azure DevOps and host the production application on Azure virtual machines.

Your team prepares an Azure Resource Manager template of the virtual machine that you mil use to test new features.

You need to create a staging environment in Azure that meetsthe following requirements:

* Minimizes the cost of Azure hosting

* Provisions the virtual machines automatically

* Use* the custom Azure Resource Manager template to provision the virtual machines

What should you do?

AIn Azure DevOps, configure new tasks in the release pipeline to create and delete the virtual machines in Azure DevTest Labs.

BFrom Azure Cloud Shell, run Azure PowerShell commands to create and delete the new virtual machines in a staging resource group.

CIn Azure DevOps, configurenew tasks in the release pipeline to deploy to Azure Cloud Services.

DIn Azure Cloud Shell, run Azure CLI commands to create and delete the new virtual machines in a staging resource group.

Answer : A

You can use the Azure DevTest Labs Tasksextension that's installed in Azure DevOps to easily integrate your CI/CD build-and-release pipeline with Azure DevTest Labs. The extension installs three tasks:

Create a VM

Create a custom image from a VM

Delete a VM

The process makes it easy to, for example, quickly deploy a 'golden image' for a specific test task and then delete it when the test is finished.

Question 7

SIMULATION

You plane to store signed images in anAzure Container Registry instance named az4009940427acr1.

You need to modify the SKU for az4009940427acr1 to support the planned images. The solution must minimize costs.

To complete this task, sign in to the Microsoft Azure portal.

ASee explanation below

Answer : A

1. Open Microsoft Azure Portal, and select the Azure Container Registry instance named az4009940427acr1.
