Question 2

SIMULATION

You need to create and configure an Azure Storage account named az400lod11566895stor in a resource group named RG1lod11566895 to store the boot diagnostics for a virtual machine named VM1.

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

ASee explanation below

Answer : A

On the Azure portal menu, select All services. In the list of resources,type Storage Accounts. As you begin typing, the list filters based on your input. Select Storage Accounts.

On the Storage Accounts window that appears, choose Add.

Select the subscription in which to create the storage account.

Under the Resource group field, select RG1lod11566895

Next, enter a name for your storage account named: az400lod11566895stor

Select Create.

Step 2: Enable boot diagnostics on existing virtual machine

To enable Boot diagnostics on an existing virtual machine, follow these steps:

1.Sign in to the Azure portal, and then select the virtual machine VM1.

2. In the Support + troubleshooting section, select Boot diagnostics, then select the Settings tab.

3. In Boot diagnostics settings, change the status to On, and from the Storage account drop-down list, select the storage account az400lod11566895stor.

4. Save the change.

You must restart the virtual machine for the change to take effect.

Question 3

You use Azure Artifacts to host NuGet packages that you create.

You need tomake one of the packages available to anonymous users outside your organization. The solution must minimize the number of publication points.

What should you do?

ACreate a new feed for the package

BPublish the package to a public NuGet repository.

CPromote the package to a release view.

DChange the feed URL of the package.

Answer : A

Azure Artifacts introduces the concept of multiple feeds that you can use to organize and control access to your packages.

Packages you host in Azure Artifacts are stored in a feed. Setting permissions on the feed allows you to share your packages with as many or as few people as your scenario requires.

Feeds have four levels of access: Owners, Contributors, Collaborators, and Readers.

Question 4

You have a GitHub repository named repol.

You commit a change to repol.

You need to update the commit message. The solution must ensure that the version number remains the same.

Which command should you run?

Agit commit --patch

Bgit commit --amend

Cgit status --renames

Dgit restore --patch

Answer : B

Question 5

You have an Azure DevOps organization named Contoso that contains a project named Project 1.

You provision an Azure key vault name Keyvault1.

You need to reference Keyvault1 secrets in a build pipeline of Project1.

What should you do first?

ACreate an XAML build service.

BCreate a variable group in Project1.

CAdd a secure file to Project1.

DConfigure the security policy of Contoso.

Answer : C

Before this will work, the build needs permission toaccess the Azure Key Vault. This can be added in the Azure Portal.

Open the Access Policies in the Key Vault and add a new one. Choose the principle used in the DevOps build.

You need to recommend an integration strategy for the build process of a Java application. The solution must meet the following requirements:

* The builds must access an on-premises dependency management system.

* The build outputs must be stored as Server artifacts in Azure DevOps.

* The source code must be stored in a Git repository in Azure DevOps.

Solution: Configure the build pipeline to use a Hosted Ubuntu agent pool. Include the Java Tool Installer task in the build pipeline. Does this meet the goal?

AYes

BNo

Answer : A

Question 7

You need to recommend an integration strategy for the build process of a Java application. The solution must meet the following requirements:

* The builds must access an on-premises dependency management system.

* The build outputs must be stored as Server artifacts in Azure DevOps.

* The source code must be stored in a Git repository in AzureDevOps.

Solution: Configure the build pipeline to use a Microsoft-hosted agent pool running a Linux image. Include the Java Tool Installer task in the build pipeline.

Does this meet the goal?

AYes

BNo

Answer : A

To run your jobs, you'll need at least one agent. A Linux agent can build and deploy different kinds of apps, including Java and Android apps.

If your pipelines are in Azure Pipelines and a Microsoft-hosted agent meets your needs, you can skip setting up a private Linux agent.

The Azure Pipelines agent pool offers several virtual machine images to choose from, each including a broad range of tools and software. We support Ubuntu, Red Hat, and CentOS.
