References: Question #9 Topic 1 Your company has an on-premises Bitbucket Server that is used for Git-based source control. The server is protected by a rewall that blocks inbound Internet tra c. 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. 5/164 6/18/2020 p AZ-400 Exam – Free Actual Q&As, Page 1 | ExamTopics 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 bene ts of GitLab CI/CD. Note: When a pipeline uses a remote, 3rd-party repository host such as Bitbucket Cloud, the repository is con gured 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 rewall, 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: Question #10 Topic 1 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.

All your messages, your les, 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. References: Question #11 Topic 1 DRAG DROP You are planning projects for three customers.
