  You use a Git repository in Azure Repos to manage the source code of a web application. Developers commit changes directly to the master branch. You need to implement a change management procedure that meets the following requirements: The master 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 master branch by using pull requests. What should you configure in Azure Repos?

  • ABranch policies of the master branch.
  • BServices in Project Settings.
  • CDeployment pools in Project Settings.
  • DBranch security of the master branch.

  You have an Azure DevOps project named Project1 and an Azure subscription named Sub1. Sub1 contains an Azure virtual machine scale set named VMSS1. VMSS1 hosts a web application named WebApp1. WebApp1 uses stateful sessions. The WebApp1 installation is managed by using the Custom Script extension. The script resides in an Azure Storage account named sa1. You plan to make a minor change to a UI element of WebApp1 and to gather user feedback about the change. You need to implement limited user testing for the new version of WebApp1 on VMSS1. Which three actions should you perform?

  • AModify the load balancer settings of VMSS1.
  • BRedeploy VMSS1.
  • CUpload a custom script file to sa1.
  • DModify the Custom Script extension settings of VMSS1.

  Litware, Inc. 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.NET 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: New incoming connections through the firewall must be minimized. Members of a group named Developers must be able to install packages. The principle of least privilege must be used for all permission assignments A branching strategy that supports developing new functionality in isolation must be used. Members of a group named Team leaders must be able to create new packages and edit the permissions of package feeds Visual Studio App Center must be used to centralize the reporting of mobile application crashes and device types in use. By default, all App Center must be used to centralize the reporting of mobile application crashes and device types in use. Code quality and release quality are critical. During release, deployments must not proceed between stages if any active bugs are logged against the release. 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. 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. 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. Which package feed access levels should be assigned to the Developers and Team Leaders groups for the investment planning applications suite?

  • ADevelopers: Reader. Team Leaders: Owner.
  • BDevelopers: Collaborator. Team Leaders: Reader.
  • CDevelopers: Contributor. Team Leaders: Owner.
  • DDevelopers: Contributor. Team Leaders: Collaborator.
