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?

Your company uses cloud-hosted Jenkins for builds. You need to ensure that Jenkins can retrieve source code from Azure Repos. Which three actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

You are automating the build process for a Java-based application by using Azure DevOps. You need to add code coverage testing and publish the outcomes to the pipeline. What should you use?

You have an existing build pipeline in Azure Pipelines. You need to use incremental builds without purging the environment between pipeline executions. What should you use?

You have a private project in Azure DevOps. You need to ensure that a project manager can create custom work item queries to report on the project's progress. The solution must use the principle of least privilege. To which security group should you add the project manager?

Your company has a project in Azure DevOps for a new application. The application will be deployed to several Azure virtual machines that run Windows Server 2019. You need to recommend a deployment strategy for the virtual machines. The strategy must meet the following requirements: • Ensure that the virtual machines maintain a consistent configuration. • Minimize administrative effort to configure the virtual machines. What should you include in the recommendation?

You have an Azure DevOps project that uses many package feeds. You need to simplify the project by using a single feed that stores packages produced by your company and packages consumed from remote feeds. The solution must support public feeds and authenticated feeds. What should you enable in DevOps?

You use a Git repository in Azure Repos to manage the source code of a web application. Developers commit changes directly to the default branch. You need to implement a change management procedure that meets the following requirements: • The default branch must be protected, and new changes must be built in the feature branches first. • Changes must be reviewed and approved by at least one release manager before each merge. • Changes must be brought into the default branch by using pull requests. What should you configure in Azure Repos?
