360. Frage
You are designing YAML-based Azure pipelines for the apps shown in the following table.
You need to configure the YAML strategy value for each app. The solution must minimize app downtime.
Which value should you configure for each app? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Antwort:
Begründung:
Explanation
App1: rolling
A rolling deployment replaces instances of the previous version of an application with instances of the new version of the application on a fixed set of virtual machines (rolling set) in each iteration.
App2: canary
Canary deployment strategy is an advanced deployment strategy that helps mitigate the risk involved in rolling out new versions of applications. By using this strategy, you can roll out the changes to a small subset of servers first. As you gain more confidence in the new version, you can release it to more servers in your infrastructure and route more traffic to it.

Topic 2, Litware inc.
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
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 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.

Task 3
Initialize the default main branch, if it floes not already exist.
You need to protect the main branch of the Project l repository to ensure that all changes are processed by using a pull request that has traceability to a work item.
Antwort:
Begründung:
See explanation below
Explanation:
Step 1: Navigate to the Project1 Repository
* In your browser, go to your Azure DevOps organization:https://dev.azure.com/
{YourOrganizationName}
* In the left menu, select the project named Project1.
* In the left menu under Repos, click on Files.
Step 2: Initialize the Main Branch (if it doesn't exist)
If the main branch doesn't exist (because the repo is empty):
* In the Repos > Files view, you'll see a message: "This repository is empty."
* Click on the Initialize button.
* Choose the default branch name as main and create a README file (or any file to initialize).
* Click Initialize.
This creates the main branch in your repository.
Step 3: Set Up Branch Protection for the Main Branch
Branch protection ensures that all changes go through a pull request (PR), and that PRs are linked to work items (for traceability).
* In the Repos view, click on Branches in the left menu.
* Locate the main branch in the list.
* Click on the three dots (...) next to main and select Branch policies.
Step 4: Configure Branch Policies for main
In the Branch policies for the main branch:
* Require a minimum number of reviewers:
* Enable this option and set to 1 or more as per your team's standards.
* Check for linked work items:
* Enable the Check for linked work items option.
* This ensures that every PR has at least one linked work item.
* Require a linked work item:
* This enforces the traceability requirement you mentioned.
* Optionally, you can also:
* Enable build validation if you have a pipeline to validate builds.
* Enforce merge strategies (like squash merge).
* Click Save changes at the bottom.
