Microsoft Microsoft Certifications AZ-400 Questions & Answers

• Question 521:

  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.

  A. a deployment group

  B. a Microsoft-hosted agent

  C. service hooks

  D. a self-hosted agent

  E. an External Git service connection

  Correct Answer: DE

  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.

• Question 522:

  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:

  1.

  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.

  2.

  Be available on Windows 10, Mac OS, iOS, and Android operating systems.

  3.

  Provide the ability to add external contractors and suppliers to projects.

  4.

  Integrate directly with Azure DevOps. What should you recommend?

  A. Microsoft Project

  B. Bamboo

  C. Octopus

  D. Slack

  Correct Answer: D

  Slack is a popular team collaboration service that helps teams be more productive by keeping all communications in one place and easily searchable from virtually anywhere. All your messages, your files, and everything from Twitter,

  Dropbox, Google Docs, Azure DevOps, and more all together. Slack also has fully native apps for iOS and Android to give you the full functionality of Slack wherever you go.

  Integrated with Azure DevOps

  This integration keeps your team informed of activity happening in its Azure DevOps projects. With this integration, code check-ins, pull requests, work item updates, and build events show up directly in your team's Slack channel.

  Note: Microsoft Teams would also be a correct answer, but it is not an option here.

  Correct Answer: C

  The initial databases for new environments must contain both schema and reference data.

  When you need to export a database for archiving or for moving to another platform, you can export the database schema and data to a BACPAC file. A BACPAC file is a ZIP file with an extension of BACPAC containing the metadata and

  data from the database. A BACPAC file can be stored in Azure Blob storage or in local storage in an on-premises location and later imported back into Azure SQL Database, Azure SQL Managed Instance, or a SQL Server instance.

  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.
