Topic Case Study: 1 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.NE T 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. https://www.exam4help.com/microsoft/az-400-dumps.html

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 companys 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 Register-AzureRmAutomationDscNode cmdlet registers an Azure virtual machine as an APS Desired State Configuration DSC node in an Azure Automation account. Scenario: 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. References: https://docs.microsoft.com/en- us/powershell/module/azurerm.automation/register- azurermautomationdscnodeviewazurermps-6.13.0 Question: 5 What should you use to implement the code quality restriction on the release pipeline for the investment planning applications suite A. a trigger B. a pre deployment approval C. a post-deployment approval D. a deployment gate Answer: B Explanation: When a release is created from a release pipeline that defines approvals the deployment stops at each point where approval is required until the specified approver grants approval or rejects the release or re-assigns the approval to another user. Scenario: Code quality and release quality are critical. During release deployments must not proceed between stages if any active bugs are logged against the release.

How should you configure the release retention policy for the investment planning applications suite To answer select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. Answer: Explanation: Scenario: By default all releases must remain available for 30 days except for production releases which must be kept for 60 days. Box 1: Set the default retention policy to 30 days The Global default retention policy sets the default retention values for all the build pipelines. Authors of build pipelines can override these values. Box 2: Set the stage retention policy to 60 days You may want to retain more releases that have been deployed to specific stages.

To build and deploy Xcode apps or Xamarin.iOS projects youll need at least one macOS agent. If your pipelines are in Azure Pipelines and a Microsoft-hosted agent meets your needs you can skip setting up a self-hosted macOS agent. Scenario: 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. References: https://docs.microsoft.com/en-us/azure/devops/pipelines/agents/v2-osxviewazure-devops Question: 8 Which branching strategy should you recommend for the investment planning applications suite A. release isolation B. main only C. development isolation D. feature isolation Answer: C Explanation: Scenario: A branching strategy that supports developing new functionality in isolation must be used. Feature isolation is a special derivation of the development isolation allowing you to branch one or more feature branches from main as shown or from your dev branches. When you need to work on a particular feature it might be a good idea to create a feature branch. Incorrect Answers: A: Release isolation introduces one or more release branches from main. The strategy allows concurrent release management multiple and parallel releases and codebase snapshots at release time. B: The Main Only strategy can be folder-based or with the main folder converted to a Branch to enable additional visibility features. You commit your changes to the main branch and optionally indicate development and release milestones with labels. C: Development isolation: When you need to maintain and protect a stable main branch you can branch one or more dev branches from main. It enables isolation and concurrent development. Work can be isolated in development branches by feature organization or temporary collaboration.

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. NOTE: Each correct selection is worth one point. Answer: Explanation: Box 1: Reader Members of a group named Developers must be able to install packages. Feeds have four levels of access: Owners Contributors Collaborators and Readers. Owners can add any type of identity-individuals teams and groups-to any access level. Box 2: Owner Members of a group named Team Leaders must be able to create new packages and edit the permissions of package feeds. https://www.exam4help.com/microsoft/az-400-dumps.html
