What AZ-400 Questions and Answers feature?

To prepare a Network Security Group (NSG) namedaz400-38443478-nsg1for hosting an Azure DevOps pipeline agent, while allowing only the required outbound port for Azure DevOps and denying all other inbound and outbound access to the Internet, follow these steps:

Create the NSG:

Navigate to the Azure Portal.

Go toNetwork Security Groupsand click on+ Create.

Fill in the details, including the nameaz400-38443478-nsg1, and create the NSG.

ConfigureOutbound Security Rules:

Once the NSG is created, go to its settings.

Navigate toOutbound security rules.

Click on+ Addto create a new rule.

Set theDestination port rangesto443, which is the required port for Azure DevOps12.

Set theProtocoltoTCP.

Set theActiontoAllow.

Assign aPrioritynumber (e.g.,100) that does not conflict with existing rules.

Provide a meaningfulNamefor the rule (e.g.,AllowAzureDevOps).

Configure Default Rules to Deny All Other Traffic:

In the sameOutbound security rulessection, edit the default rule to deny alltraffic.

Change theActiontoDenyfor the rule with the lowest priority (highest number).

Ensure that this rule applies to all protocols, source and destination IP ranges, and port ranges.

Associate the NSG with the Appropriate Resource:

Associate the NSGwith the subnet or network interface of the virtual machine or resource where the Azure DevOps pipeline agent will be hosted.

By following these steps, you will ensure that the Azure DevOps pipeline agent can communicate with Azure DevOps services over the required port while blocking all other inbound and outbound Internet access, adhering to the principle of least privilege and security best practices.

Step 1: Initialize the Default Main Branch

Navigate to Azure DevOps:

Go to Azure DevOps and sign in with your credentials.

Select Your Project:

Choose Project1 from your list of projects.

Initialize theMain Branch:

Go to Repos > Files.

If the main branch does not exist, you will see an option to initialize it. Click on Initialize and follow the prompts to create the main branch1.

Step 2: Create a New Branch for the Pipeline

Navigate to Branches:

Go to Repos > Branches.

Click on New branch.

Create the Branch:

Enter azure-pipelines as the branch name.

Select main as the base branch.

Click Create2.

Step 3: Create a New Azure Pipelines YAML Pipeline

Navigate to Pipelines:

Go to Pipelines > New pipeline.

Select the Repository:

Choose Azure Repos Git and select the relevant repository.

Configure the Pipeline:

Select Starter pipeline.

Replace the default YAML with the ASP.NET template. You can find the ASP.NET template in the Azure Pipelines documentation oruse the following example:

trigger:

- main

pool:

vmImage: 'windows-latest'

variables:

buildConfiguration: 'Release'

steps:

- task: UseDotNet@2

inputs:

packageType: 'sdk'

version: '5.x'

installationPath: $(Agent.ToolsDirectory)/dotnet

- script: |

dotnet build --configuration $(buildConfiguration)

displayName: 'Build project'

- script: |

dotnet test --no-build --configuration $(buildConfiguration)

displayName: 'Run tests'

Save the Pipeline:

Click on Save and enter azure-pipelines as the branch name.

Click on Save and run to save the pipeline to the new branch named azure-pipelines3.

By following these steps, you will have successfully initialized the main branch, created a new branch named azure-pipelines, and set up a new Azure Pipelines YAML pipeline using the ASP.NET template

Task 11: Create an Artifact Feed with Specific Retention Policies

Step 1: Navigate to Artifacts

In your Azure DevOps Project (Project1), click on the Artifacts section in the left menu.

Step 2: Create a New Feed

Click on the + New feed button.

In the Name field, enter:

Copy

artifact_feed

Choose the visibility of the feed:

Project scoped (only accessible to Project1).

Or Organization scoped (accessible across your Azure DevOps organization).

Leave other settings at default unless you have specific permissions or upstream sources.

Click Create.

This creates a new feed named artifact_feed.

Step 3: Configure Retention Policies

In the Artifacts section, click on the feed named artifact_feed to open its details page.
