1. Question 321 · 540 in bank

   Your company uses a Git repository in Azure Repos to manage the source code of a web application. The master branch is protected from direct updates. Developers work on new features in the topic branches. Because of the high volume of requested features, it is difficult to follow the history of the changes to the master branch. You need to enforce a pull request merge strategy. The strategy must meet the following requirements: ✑ Consolidate commit histories. ✑ Merge the changes into a single commit. Which merge strategy should you use in the branch policy?

   • Asquash merge
   • Bfast-forward merge
   • CGit fetch
   • Dno-fast-forward merge

   Show answer

   Answer: A

   Explanation

   Squash merging is a merge option that allows you to condense the Git history of topic branches when you complete a pull request From https://docs.microsoft.com/en-us/azure/devops/repos/git/merging-with-squash?view=azure-devops A is the answer

   DRAG DROP - Your company has four projects. The version control requirements for each project are shown in the following table.

   

   You plan to use Azure Repos for all the projects. Which version control system should you use for each project? To answer, drag the appropriate version control systems to the correct projects. Each version control system may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point. Select and Place:

   

   This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.

   Answer: See figure below

   Explanation

   Box 1: Team Foundation Version Control TFVC lets you apply granular permissions and restrict access down to a file level. Box 2: Git - Git is the default version control provider for new projects. You should use Git for version control in your projects unless you have a specific need for centralized version control features in TFVC. Box 3: Subversion - Note: Xcode is an integrated development environment (IDE) for macOS containing a suite of software development tools developed by Apple Box 4: Git - Note: Perforce: Due to its multitenant nature, many groups can work on versioned files. The server tracks changes in a central database of MD5 hashes of file content, along with descriptive meta data and separately retains a master repository of file versions that can be verified through the hashes.

   Answer: See figure below

   Explanation

   Box 1: Hosted macOS - Hosted macOS pool (Azure Pipelines only): Enables you to build and release on macOS without having to configure a self-hosted macOS agent. This option affects where your data is stored. Box 2: Hosted - Hosted pool (Azure Pipelines only): The Hosted pool is the built-in pool that is a collection of Microsoft-hosted agents. Incorrect Answers: Default pool: Use it to register self-hosted agents that you've set up. Hosted Windows Container pool (Azure Pipelines only): Enabled you to build and release inside Windows containers. Unless you're building using containers, Windows builds should run in the Hosted VS2017 or Hosted pools. Hosted Linux/Ubuntu 18.04 does not apply for Mac OS or for Microsoft IIS.

   Answer: See figure below

   Explanation

   App1: rolling - A rolling deployment replaces instances of the previous version of an application with instances of the new version of the application on a fixed set of virtual machines (rolling set) in each iteration. App2: canary - Canary deployment strategy is an advanced deployment strategy that helps mitigate the risk involved in rolling out new versions of applications. By using this strategy, you can roll out the changes to a small subset of servers first. As you gain more confidence in the new version, you can release it to more servers in your infrastructure and route more traffic to it. Incorrect Answers: runonce: runOnce is the simplest deployment strategy wherein all the lifecycle hooks, namely preDeploy deploy, routeTraffic, and postRouteTraffic, are executed once. Then, either on: success or on: failure is executed. Reference: https://docs.microsoft.com/en-us/azure/devops/pipelines/process/deployment-jobs

9. Question 329 · 540 in bank

   You have a project in Azure DevOps. You create the following YAML template named Template1.yml. steps: - script: npm install - script: yarn install - script: npm run compile You create the following pipeline named File1.yml. parameters: usersteps: - task: MyTask@1 - script: echo Done You need to ensure that Template1.yaml runs before File1.yml. How should you update File1.yml?

   • Aparameters: usersteps: extends: template: template1.yml - task: MyTask@1 - script: echo Done
   • Btemplate: template1.yml parameters: usersteps: - task: MyTask@1 - script: echo Done
   • Cextends: template: templatel.yml parameters: usersteps: - task: MyTask@1 - script: echo Done
   • Dparameters: usersteps: - template: templatel.yml - task: MyTask@1 - script: echo Done

   Show answer

   Answer: C

   Explanation

   Answer should be B. template: template1.yml Explanation: To ensure that the Template1.yaml runs before File1.yml, you can use the template keyword in File1.yml to reference Template1.yaml. The parameters section is used to pass values to the referenced template. In this case, we need to pass the usersteps parameter from File1.yml to Template1.yaml. Therefore, we need to include the parameters section in File1.yml, and reference the usersteps parameter in Template1.yaml. The correct syntax is shown in option B. https://learn.microsoft.com/en-us/azure/devops/pipelines/process/templates?view=azure-devops#step-reuse
