Technical Requirements and Planned Changes

Planned Changes
Woodgrove Bank plans to implement the following project management changes:
Implement Azure DevOps for project tracking.

Woodgrove Bank plans to implement the following changes to the identity environment:
Deploy an Azure AD tenant named woodgrovebank.com.
Sync the Active Directory domain to Azure AD.
Configure App1 to use a service principal.
Integrate GitHub with Azure AD.

Woodgrove Bank plans to implement the following changes to the core apps:
Migrate App1 to ASP.NET Core.
Integrate Azure Pipelines and the third-party build tool used to develop App2.
Woodgrove Bank plans to implement the following changes to the DevOps environment:
Deploy App1 to Azure App Service.
Implement source control for the DB1 schema.
Migrate all the source code from TFS1 to GitHub.
Deploy App2 to an Azure virtual machine named VM1.
Merge the POC branch into the GitHub default branch.
Implement an Azure DevOps dashboard for stakeholders to monitor development progress.

Technical Requirements
Woodgrove Bank identifies the following technical requirements:
The initial databases for new environments must contain both schema and reference data.
An Azure Monitor alert for VM1 must be configured to meet the following requirements:
- Be triggered when average CPU usage exceeds 80 percent for 15 minutes.
- Calculate CPU usage averages once every minute.
The commit history of the POC branch must replace the history of the default branch.
The Azure DevOps dashboard must display the metrics shown in the following table.



Access to Azure DevOps must be restricted to specific IP addresses.
Page load times for App1 must be captured and monitored.
Administrative effort must be minimized.
You need to meet the technical requirements for controlling access to Azure DevOps.
What should you use?

You are developing an iOS application by using Azure DevOps.
You need to test the application manually on 10 devices without releasing the application to the public.
Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

DRAG DROP
You have an Azure Kubernetes Service (AKS) implementation that is RBAC-enabled.
You plan to use Azure Container Instances as a hosted development environment to run containers in the AKS implementation.
You need to configure Azure Container Instances as a hosted environment for running the containers in AKS.
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 them in the correct order.

SIMULATION
Initialize the default main branch, if it does not exist already.
In Project1, you need to create a new Azure Pipelines YAML pipeline by using the ASP.NET template.
The pipeline must use Azure Repos as the hosting platform and must be created in a new branch named azure-pipelines.

Overview
Litware, Inc. is an independent software vendor (ISV). Litware has a main office and five branch offices.

Existing Environment
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 di cult 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.

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 existing 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 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 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 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
Where should the build and release agents for the investment planning applications suite run? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
