1. Topic 1, Litware inc. Case Study: 1

Overview
Existing Environment
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.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.
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

• 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.

Current Technical
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.

To resolve the current technical issue, what should you do to the Register-AzureRmAutomationDscNode command?

A. Change the value of the ConfigurationMode parameter.
B. Replace the Register-AzureRmAutomationDscNode cmdlet with Register-AzureRmAutomationScheduledRunbook
C. Add the AllowModuleOverwrite parameter.

Question 153 Selectable Answer

This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have an Azure DevOps project.
Your build process creates several artifacts.
You need to deploy the artifacts to on-premises servers.
Solution: You deploy an Azure self-hosted agent to an on-premises server. You add a Copy and Publish Build Artifacts task to the deployment pipeline.
Does this meet the goal?

A. Yes
B. No

Answer:
Explanation:
To build your code or deploy your software using Azure Pipelines, you need at least one agent.
If your on-premises environments do not have connectivity to a Microsoft-hosted agent pool (which is typically the case due to intermediate firewalls), you'll need to manually configure a self-hosted agent on on-premises computer(s). The agents must have connectivity to the target on-premises environments, and access to the Internet to connect to Azure Pipelines or Team Foundation Server.

Question 154 Selectable Answer

You have an Azure DevOps project that contains a release pipeline and a Git repository.
When a new code revision is committed to the repository, a build and release is triggered.
You need to ensure that release information for the pipeline is added automatically to the work items associated to the Git commit.
What should you do?

A. Modify the Integrations options for the pipeline.
B. Modify the post-deployment conditions for the last stage of the pipeline.
C. Add an agentless job to the pipeline.
D. Modify the service hooks for the project.

Answer:
Explanation:
Service hooks in Azure DevOps allow you to trigger actions in other tools based on events that occur in your Azure DevOps project. To automatically add release information to work items associated with a Git commit, you would need to configure a service hook that listens for commit events in your Git repository, and then sends the release information to the appropriate work items.
Here's the steps you can follow to set up a service hook for this purpose:
✑ In your Azure DevOps project, navigate to the project settings by clicking on the gear icon in the top right corner of the page.
✑ Select "Service Hooks" from the left-hand menu.
✑ Click on the "New Subscription" button to create a new service hook.
✑ In the "Event" drop-down menu, select "Code pushed" to trigger the service hook when a new code revision is committed to the repository.
✑ In the "Actions" section, select the action that you want to take place when the service hook is triggered. For example, you might use the "Link work items to commits" action to automatically associate work items with the relevant commits.
✑ Configure the remaining settings as needed, and then click on the "Create" button to create the service hook.

You need to implement the code flow strategy for Project2 in Azure DevOps.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange in the correct order.

Answer:

Explanation:
Step 1: Create a repository
A Git repository, or repo, is a folder that you've told Git to help you track file changes in. You can have any number of repos on your computer, each stored in their own folder.
Step 2: Create a branch
Branch policies help teams protect their important branches of development. Policies enforce your team's code quality and change management standards.
Step 3: Add a build validation policy
When a build validation policy is enabled, a new build is queued when a new pull request is created or when changes are pushed to an existing pull request targeting this branch. The build policy then evaluates the results of the build to determine whether the pull request can be completed.
Scenario:
Implement a code flow strategy for Project2 that will:
- Enable Team2 to submit pull requests for Project2.
- Enable Team2 to work independently on changes to a copy of Project2.
- Ensure that any intermediary changes performed by Team2 on a copy of Project2 will be subject to the same restrictions as the ones defined in the build policy of Project2.
