   Answer: D

   Explanation

   I didn't get this question on my exam on September 12, 2023, but I did get another that was very similar. It asked something about what to use when working in a new feature and the answers were short-lived feature branches.

   Select 2

   You manage a project by using Azure Boards, and you manage the project code by using GitHub repositories. You have a work item that has an ID of 123. You need to link a commit message in GitHub to work item 123 on the board. What are two ways to achieve the goal? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

   • AFrom the Development settings of work item 123, select Add link, and then enter the URL of the commit.
   • BAdd AB#123 to the text of the commit message.
   • CAdd GH-123 to the text of the commit message.
   • DFrom the Links settings of work item 123, select Add link, select Existing item, and then enter the URL of the commit.
   • ETo work item 123, add a comment that includes the URL of the commit.

   Show answer

   Answer: AB

   Explanation

   Option A is not correct because the Development section in Azure Boards does not provide a direct way to add a link to a commit by entering its URL. Instead, linking commits to work items is typically done through the commit message itself or through the Links settings. Using AB#123 in the commit message (Option B) is a straightforward way to automatically link the commit to the work item.

9. Question 309 · 540 in bank

   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 integrate a cloud-hosted Jenkins server and a new Azure DevOps deployment. You need Azure DevOps to send a notification to Jenkins when a developer commits changes to a branch in Azure Repos. Solution: You create a service hook subscription that uses the build completed event. Does this meet the goal?

   • AYes
   • BNo

   Show answer

   Answer: B

   Explanation

   But the description also says that the event should be "code pushed", not "build completed", so that's why the answer is "No".

10. Question 310 · 540 in bank

    You have a project in Azure DevOps that uses an Azure Boards board and stores code in a GitHub repository. The repository contains a file named README.md. You need to ensure that README.md includes the status of the work items on the board. The solution must minimize administrative effort. What should you do first?

    • ACreate a GitHub personal access token (PAT).
    • BEnable GitHub annotations for the board.
    • CInstall the Azure Boards app for GitHub.
    • DSelect Allow anonymous users to access the status badge.

    Show answer

    Answer: C

    Explanation

    Given answer is correct : Install the Azure Boards app for GitHub. The Azure Boards app for GitHub allows you to link GitHub commits and pull requests to your Azure Boards work items. Therefore, when the status of a work item on the Azure Boards changes, this change will reflect on the README.md file on GitHub.
