NO.123 Task 5
For Project1, you need to create a project wiki named Wiki1 that uses the Mermaid syntax to render a diagram A sample of the desired output is stored in C:ResourcesTCPHandshake.png.

See the solution below in explanation.
Explanation:
Step 1: Create a Project Wiki
* Navigate to Azure DevOps:
* Go to Azure DevOps and sign in with your credentials.
* Select Your Project:
* Choose Project1 from your list of projects.
* Create a Wiki:
* In the left-hand menu, select Wiki.
* Click on Create project wiki.
* Enter the name Wiki1 and click Create.
Step 2: Add Mermaid Syntax to Render a Diagram
* Open the Wiki Page:
* Navigate to the newly created Wiki1.
* Edit the Wiki Page:
* Click on Edit to start editing the wiki page.
* Insert Mermaid Diagram:
* Use the following Mermaid syntax to render a diagram. For example, to render a simple flowchart, you can use:
“`mermaid
graph TD;
A–>B;
A–>C;
B–>D;
C–>D;
* Save the Page:
* Click on Save to save your changes.
Step 3: Render the TCP Handshake Diagram
* Convert TCPHandshake.png to Mermaid Syntax:
* Since you have a sample diagram in C:\Resources\TCPHandshake.png, you need to convert this diagram into Mermaid syntax. Here’s an example of how a TCP handshake might look in Mermaid syntax:
“`mermaid
sequenceDiagram
participant Client
participant Server
Client->>Server: SYN
Server–>>Client: SYN-ACK
Client->>Server: ACK

NO.130 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.

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.

Box1: Private
In App Center, distribution groups are private by default. Only testers invited via email can access the releases available to this group.
Box 2: Public
Distribution groups must be public to enable unauthenticated installs from public links.
Box 3: Shared
Shared distribution groups are private or public distribution groups that are shared across multiple apps in a single organization.

The master branch must be protected, and new changes must be built in the feature branches first.
Changes must be reviewed and approved by at least one release manager before each merge.
Changes must be brought into the master branch by using pull requests.
What should you configure in Azure Repos?

branch policies of the master branch

Services in Project Settings

Deployment pools in Project Settings

branch security of the master branch
Branch policies help teams protect their important branches of development. Policies enforce your team’s
code quality and change management standards.

Reference:
https://docs.microsoft.com/en-us/azure/devops/repos/git/branch-policies

Microsoft offers an official extension for publishing and managing your private NuGet feeds.
Step 3: Publish the package.
Publish, pack and push the built project to your NuGet feed.
Step 4: Connect to an Azure Artifacts feed.
With the package now available, you can point Visual Studio to the feed, and download the newly published package References:

NO.139 You have an Azure DevOps organization named Contoso.
You need to recommend an authentication mechanism that meets the following requirements:
* Supports authentication from Git
* Minimizes the need to provide credentials during authentication
What should you recommend?

managed identities in Azure Active Directory (Azure AD)

personal access tokens (PATs) in Azure DevOps

user accounts in Azure Active Directory (Azure AD)

Alternate credentials in Azure DevOps

Explanation
Personal access tokens (PATs) give you access to Azure DevOps and Team Foundation Server (TFS), without using your username and password directly. These tokens have an expiration date from when they’re created.
You can restrict the scope of the data they can access. Use PATs to authenticate if you don’t already have SSH keys set up on your system or if you need to restrict the permissions that are granted by the credential.

NO.140 Your company uses Git as a source code control system for a complex app named App1.
You plan to add a new functionality to App1.
You need to design a branching model for the new functionality.
Which branch lifetime and branch time should you use in the branching model? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Explanation:

Branch lifetime: Short-lived
Branch type: Feature
Feature branches are used when developing a new feature or enhancement which has the potential of a development lifespan longer than a single deployment. When starting development, the deployment in which this feature will be released may not be known. No matter when the feature branch will be finished, it will always be merged back into the master branch.

NO.141 You are developing a multi-tier application. The application will use Azure App Service web apps as the front end and an Azure SQL database as the back end. The application will use Azure functions to write some data to Azure Storage.
You need to send the Azure DevOps team an email message when the front end fails to return a status code of
200.
Which feature should you use?

Service Map in Azure Log Analytics

Availability tests in Azure Application Insights

Profiler in Azure Application Insights

Application Map in Azure Application Insights

Application Map helps you spot performance bottlenecks or failure hotspots across all components of your distributed application. Each node on the map represents an application component or its dependencies; and has health KPI and alerts status.
Incorrect Answers:
A: Service Map automatically discovers application components on Windows and Linux systems and maps the communication between services. You can use it to view your servers as you think of them–interconnected systems that deliver critical services. Service Map shows connections between servers, processes, and ports across any TCP-connected architecture with no configuration required, other than installation of an agent.

NO.142 Your company is creating a suite of three mobile applications.
You need to control access to the application builds. The solution must be managed at the organization level What should you use? To answer, select the appropriate options m the answer area.
NOTE: Each correct selection is worth one point.

Explanation:
Box 1: Microsoft Visual Studio App Center distribution Groups
Distribution Groups are used to control access to releases. A Distribution Group represents a set of users that can be managed jointly and can have common access to releases. Example of Distribution Groups can be teams of users, like the QA Team or External Beta Testers or can represent stages or rings of releases, such as Staging.
Box 2: Shared
Shared distribution groups are private or public distribution groups that are shared across multiple apps in a single organization. Shared distribution groups eliminate the need to replicate distribution groups across multiple apps.
Note: With the Deploy with App Center Task in Visual Studio Team Services, you can deploy your apps from Azure DevOps (formerly known as VSTS) to App Center. By deploying to App Center, you will be able to distribute your builds to your users.
