Demo Questions

Question 1
You use Azure Artifacts to host NuGet packages that you create. 
You need to make one of the packages available to anonymous users outside your organization. The solution must minimize the number of publication points. 
What should you do?
  1. Change the feed URL of the package
  2. Create a new feed for the package
  3. Promote the package to a release view.
  4. Publish the package to a public NuGet repository.
Correct answer: B
Explanation:
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.References: https://docs.microsoft.com/en-us/azure/devops/artifacts/feeds/feed-permissions?view=vsts&tabs=new-nav

Question 2
Your company plans to use an agile approach to software development. 
You need to recommend an application to provide communication between members of the development team who work in locations around the world. The applications must meet the following requirements:
  • Provide the ability to isolate the members of different project teams into separate communication channels and to keep a history of the chats within those channels. 
  • Be available on Windows 10, Mac OS, iOS, and Android operating systems. 
  • Provide the ability to add external contractors and suppliers to projects. 
  • Integrate directly with Azure DevOps. 
What should you recommend?
  1. Microsoft Project
  2. Bamboo
  3. Microsoft Lync
  4. Microsoft Teams
Correct answer: D
Explanation:
Within each team, users can create different channels to organize their communications by topic. Each channel can include a couple of users or scale to thousands of users. Microsoft Teams works on Android, iOS, Mac and Windows systems and devices. It also works in Chrome, Firefox, Internet Explorer 11 and Microsoft Edge web browsers. The guest-access feature in Microsoft Teams allows users to invite people outside their organizations to join internal channels for messaging, meetings and file sharing. This capability helps to facilitate business-to-business project management. Teams integrates with Azure DevOps. References: https://searchunifiedcommunications.techtarget.com/definition/Microsoft-Teams

Question 4
Your company has an on-premises Bitbucket Server that is used for Git-based source control. The server is protected by a firewall that blocks inbound Internet traffic. 
You plan to use Azure DevOps to manage the build and release processes. 
Which two components are required to integrate Azure DevOps and Bitbucket? Each correct answer presents part of the solution. 
NOTE: Each correct selection is worth one point.
  1. a deployment group
  2. a Microsoft-hosted agent
  3. service hooks
  4. a self-hosted agent
  5. an External Git service connection
Correct answer: DE
Explanation:
E: GitLab CI/CD can be used with GitHub or any other Git server such as BitBucket. Instead of moving your entire project to GitLab, you can connect your external repository to get the benefits of GitLab CI/CD.Note: When a pipeline uses a remote, 3rd-party repository host such as Bitbucket Cloud, the repository is configured with webhooks that notify Azure Pipelines Server or TFS when code has changed and a build should be triggered. Since on-premises installations are normally protected behind a firewall, 3rd-party webhooks are unable to reach the on-premises server. As a workaround, you can use the External Git repository type which uses polling instead of webhooks to trigger a build when code has changed.References: https://docs.microsoft.com/en-us/azure/devops/pipelines/repos/pipeline-options-for-git

Question 5
During a code review, you discover many quality issues. Many modules contain unused variables and empty catch blocks. 
You need to recommend a solution to improve the quality of the code. 
What should you recommend?
  1. In a Grunt build task, select Enabled from Control Options.
  2. In a Maven build task, select Run PMD.
  3. In a Xcode build task, select Use xcpretty from Advanced.
  4. In a Gradle build task, select Run Checkstyle.
Correct answer: B
Explanation:
PMD is a source code analyzer. It finds common programming flaws like unused variables, empty catch blocks, unnecessary object creation, and so forth. There is an Apache Maven PMD Plugin which allows you to automatically run the PMD code analysis tool on your project's source code and generate a site report with its results. Incorrect Answers:C: xcpretty is a fast and flexible formatter for xcodebuild.References: https://pmd.github.io/

Question 6
You are developing a multi-tier application. The application will use Azure App Service web apps as the front end and an Azure SQL database as the back end. The application will use Azure functions to write some data to Azure Storage. 
You need to send the Azure DevOps team an email message when the front end fails to return a status code of 200. 
Which feature should you use?
  1. Service Map in Azure Log Analytics
  2. Availability tests in Azure Application Insights
  3. Profiler in Azure Application Insights
  4. Application Map in Azure Application Insights
Correct answer: D
Explanation:
Application Map helps you spot performance bottlenecks or failure hotspots across all components of your distributed application. Each node on the map represents an application component or its dependencies; and has health KPI and alerts status. Incorrect Answers:A: Service Map automatically discovers application components on Windows and Linux systems and maps the communication between services. You can use it to view your servers as you think of them--interconnected systems that deliver critical services. Service Map shows connections between servers, processes, and ports across any TCP-connected architecture with no configuration required, other than installation of an agent.References: https://docs.microsoft.com/en-us/azure/azure-monitor/app/app-map

Question 9
Your company builds a multi-tier web application. 
You use 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 will use to test new features. 
You need to create a staging environment in Azure that meets the following requirements:
  • Minimizes the cost of Azure hosting 
  • Provisions the virtual machines automatically 
  • Uses the custom Azure Resource Manager template to provision the virtual machines 
What should you do?
  1. In Azure Cloud Shell, run Azure CLI commands to create and delete the new virtual machines in a staging resource group.
  2. In Azure DevOps, configure new tasks in the release pipeline to deploy to Azure Cloud Services.
  3. From Azure Cloud Shell, run Azure PowerShell commands to create and delete the new virtual machines in a staging resource group.
  4. In Azure DevOps, configure new tasks in the release pipeline to create and delete the virtual machines in Azure DevTest Labs.
Correct answer: D
Explanation:
You can use the Azure DevTest Labs Tasks extension 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. References: https://docs.microsoft.com/en-us/azure/lab-services/devtest-lab-integrate-ci-cd-vsts

Question 10
You have a branch policy in a project in Azure DevOps. The policy requires that code always builds successfully. 
You need to ensure that a specific user can always merge changes to the master branch, even if the code fails to compile. The solution must use the principle of least privilege. 
What should you do?
  1. Add the user to the Build Administrators group.
  2. Add the user to the Project Administrators group.
  3. From the Security settings of the repository, modify the access control for the user.
  4. From the Security settings of the branch, modify the access control for the user.
Correct answer: D
Explanation:
In some cases, you need to bypass policy requirements so you can push changes to the branch directly or complete a pull request even if branch policies are not satisfied. For these situations, grant the desired permission from the previous list to a user or group. You can scope this permission to an entire project, a repo, or a single branch. Manage this permission along the with other Git permissions. References: https://docs.microsoft.com/en-us/azure/devops/repos/git/branch-policies
