    AZ-400 Exam Question 4

    Case Study 1 - Litware
    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.NET web forms that use logic written in VB.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 live 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 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.
    Customers report that bug reporting is overly complex.
    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 existing retirement fund management system.
    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.
    Litware plans to move to a more agile development methodology. Shared code will be extracted into a series of packages.
    Litware has started an internal cloud transformation process and plans to use cloud-based services whenever suitable.
    Litware wants to become proactive in detecting failures, rather than always waiting for customer bug reports.
    Technical requirements
    The company's investment planning applications suite must meet the following 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 releases must remain available for 30 days, except for production releases, which must be kept for 60 days.
    * 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 HTTPS.
    * The required operating system configuration for the test servers changes weekly. Azure Automation State Configuration must be used to ensure that the operating system on each test server is configured the same way when the servers are created and checked periodically.
    Current Technical Issue
    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.

    Drag and Drop Question
    Which package feed access levels should be assigned to the Developers and Team Leaders groups for the investment planning applications suite? To answer, drag the appropriate access levels to the correct groups. Each access level may be used once, more than once, or not at all.
    You may need to drag the split bar between panes or scroll to view content.
