    Answer:

    Explanation:
    Box 1: Reader
    Members of the Reader role can view the organization agent pool as well as agents. You typically use this to add operators that are responsible for monitoring the agents and their health.
    Box 2: Service account
    Members of the Service account role can use the organization agent pool to create a project agent pool in a project. If you follow the guidelines above for creating new project agent pools,
    you typically do not have to add any members here. Incorrect Answers:
    In addition to all the permissions given the Reader and the Service Account role, members of the administrator role can register or unregister agents from the organization agent pool. They can also refer to the organization agent pool when creating a project agent pool in a project. Finally, they can also manage membership for all roles of the organization agent pool. The user that created the organization agent pool is automatically added to the Administrator role for that pool.

      NEW QUESTION 3
      Your company uses a Git repository in Azure Repos lo 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:
      ¡E Consolidate commit histories
      ¡E Merge tie changes into a tingle commit
      Which merge strategy should you use in the branch policy?

      • A. Git fetch
      • B. no-fast-forward merge
      • C. squash merge
      • D. fast-forward merge

      Answer: C

      Explanation: Squash merging is a merge option that allows you to condense the Git history of topic branches when you complete a pull request. Instead of each commit on the topic branch being added to the history of the default branch, a squash merge takes all the file changes and adds them to a single new commit on the default branch. A simple way to think about this is that squash merge gives you just the file changes, and a regular merge gives you the file changes and the commit history. Note: Squash merging keeps your default branch histories clean and easy to follow without demanding any workflow changes on your team. Contributors to the topic branch work how they want in the topic branch, and the default branches keep a linear history through the use of squash merges. The commit history of a master branch updated with squash merges will have one commit for each merged branch. You can step through this history commit by commit to find out exactly when work was done.

      How should you confrere the release retention policy for the investment planning depletions suite? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
      AZ-400 dumps exhibit

        Answer:

        Explanation: Every request made against a storage service must be authorized, unless the request is for a blob or container resource that has been made available for public or signed access. One option for authorizing a request is by using Shared Key. Scenario: The mobile applications must be able to call the share pricing service of the existing retirement fund management system. Until the system is upgraded, the service will only support basic authentication over HTTPS.
        The investment planning applications suite will include one multi-tier web application
        and two iOS mobile application. One mobile application will be used by employees; the other will be used by customers.

        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?

        • A. Create a new feed for the package
        • B. Publish the package to a public NuGet repository.
        • C. Promote the package to a release view.
        • D. Change the feed URL of the packag

        Answer: A

        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.

        You need to implement the code flow strategy for Project2 in Azure DevOps. Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange in the correct order.
        AZ-400 dumps exhibit

          Answer:

          Explanation: Step 1: Create a repository
          A Git repository, or repo, is a folder that you've told Git to help you track file changes in. You can have any number of repos on your computer, each stored in their own folder.
          Step 2: Create a branch
          Branch policies help teams protect their important branches of development. Policies enforce your team's code quality and change management standards. Step 3: Add a build validation policy
          When a build validation policy is enabled, a new build is queued when a new pull request is created or when changes are pushed to an existing pull request targeting this branch. The build policy then evaluates the results of the build to determine whether the pull request can be completed.
          Scenario:
          Implement a code flow strategy for Project2 that will: Enable Team2 to submit pull requests for Project2.
          Enable Team2 to work independently on changes to a copy of Project2.
          Ensure that any intermediary changes performed by Team2 on a copy of Project2
          will be subject to the same restrictions as the ones defined in the build policy of Project2.

          Explanation: Case Study: 1 Overview
          Existing Environment
          Litware, Inc. e an independent software vendor (ISV) Litware has a main office and five branch offices.
          Application Architecture
          The company¡¦ s primary application is a single monolithic retirement fund management system based on ASP.NE T web forms that use logic written in V8.NET. Some new sections of the application are written in C#.
          Variations of the application are created for individual customers. Currently, there are more than 80 have code branches in the application¡¦s code base.
          The application was developed by using Microsoft Visual Studio. Source code is stored in Team Foundation Server (TFS) in the main office. The branch offices access of the source code by using TFS proxy servers.
          Architectural Issues
          Litware focuses on writing new code for customers. No resources are provided to refactor or remove existing code. Changes to the code base take a long time, AS dependencies are not obvious to individual developers.
          Merge operations of the code often take months and involve many developers. Code merging frequently introduces bugs that are difficult to locate and resolve.
          Customers report that ownership costs of the retirement fund management system increase continually. The need to merge unrelated code makes even minor code changes expensive.
          Requirements Planned Changes
          Litware plans to develop a new suite of applications for investment planning. The investment planning Applications will require only minor integration with the easting retirement fund management system.
          The investment planning applications suite will include one multi-tier web application and two iOS mobile applications. One mobile application will be used by employees; the other will be used by customers.
          Litware plans to move to a more agile development methodology. Shared code will be extracted into a series of package.
          Litware has started an internal cloud transformation process and plans to use cloud based services whenever suitable.
          Litware wants to become proactive m detecting failures, rather than always waning for customer bug reports.
          Technical Requirements
          The company's investment planning applications suite must meet the following technical requirements:
          ¡E New incoming connections through the firewall must be minimized.
          ¡E Members of a group named Developers must be able to install packages.
          ¡E The principle of least privilege must be used for all permission assignments
          ¡E A branching strategy that supports developing new functionality in isolation must be used.
          ¡E Members of a group named Team leaders must be able to create new packages and edit the permissions of package feeds
          ¡E Visual Studio App Center must be used to centralize the reporting of mobile application crashes and device types in use.
          ¡E By default, all App Center must be used to centralize the reporting of mobile application crashes and device types in use.
          ¡E Code quality and release quality are critical. During release, deployments must not proceed between stages if any active bugs are logged against the release.
          ¡E The mobile applications must be able to call the share pricing service of the existing retirement fund management system. Until the system is upgraded, the service will only support basic authentication over HUPS.
          ¡E The required operating system configuration tor the test servers changes weekly. Azure Automation State Configuration must be used to ensure that the operating system on each test servers configured the same way when the servers are created and checked periodically.
          Current Technical
          The test servers are configured correctly when first deployed, but they experience configuration drift over time. Azure Automation State Configuration fails to correct the configurations.
          Azure Automation State Configuration nodes are registered by using the following command.

          NEW QUESTION 10
          What should you use to implement the code quality restriction on the release pipeline for the investment planning applications suite?

          • A. a trigger
          • B. a pre deployment approval
          • C. a post-deployment approval
          • D. a deployment gate

          Answer: B

          Explanation: When a release is created from a release pipeline that defines approvals, the deployment stops at each point where approval is required until the specified approver grants approval or rejects the release (or re-assigns the approval to another user).

                AZ-400 dumps exhibit
                In this example, a release of a website is created by collecting specific versions of two builds (artifacts), each from a different build pipeline. The release is first deployed to a Dev stage and then forked to two QA stages in parallel. If the deployment succeeds in both the QA stages, the release is deployed to Prod ring 1 and then to Prod ring 2. Each production ring represents multiple instances of the same website deployed at various locations around the globe.
