Question
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. Hotspot Question You need to configure a cloud service to store the secrets required by the mobile applications to call the share pricing service. What should you include in the solution?

Explanation
This hotspot question tests knowledge of Azure DevOps migration strategies and architectural decisions for Litware, Inc., an ISV dealing with a legacy monolithic ASP.NET application with complex branching, merging issues, and technical debt.
Approach. The correct approach involves evaluating each hotspot statement against the described environment. Litware should migrate from TFS to Azure DevOps (Azure Repos with Git), replacing the 80+ TFS branches with a trunk-based or feature-branch Git strategy to reduce merge conflicts and improve CI/CD. Dependency issues and long merge cycles suggest adopting a microservices decomposition over time, and implementing Azure Pipelines for automated builds and testing to catch bugs earlier. Branch office proxy server usage maps to Git's distributed nature, which inherently solves the TFS proxy dependency. For each Yes/No hotspot row, the answer is determined by whether the proposed action aligns with Azure DevOps best practices and resolves the specific pain points described (long merges, hidden dependencies, costly ownership, and code branch proliferation).
Concept tested. Azure DevOps migration planning, Git branching strategies vs TFS, CI/CD pipeline design, and architectural modernization of legacy monolithic applications to address merge complexity, dependency management, and branch proliferation in an ISV context.
