Microsoft Azure AZ-400 Release Date

Step 1: Access Azure DevOps

Open your browser and navigate to .

You will be prompted to sign in. Enter the following credentials:

Username: UserUser1-48901628@cxamUsers.com

Password: aFpJ2j-6M!

Click Next or Sign in to proceed.

Note: If you see any Microsoft security challenge (like phone or email verification), follow the instructions to complete it.

Step 2: Sign Up for Azure DevOps

After signing in, you’ll see a prompt to sign up for Azure DevOps.

Use the default settings provided by Azure DevOps for the sign-up process (region, default name, etc.).

Click Continue or Start free with Azure DevOps.

An Azure DevOps Organization is a container for your projects and resources. Default settings are usually fine for new organizations.

Step 3: Create the Organization

Enter a name for your organization. Azure DevOps will suggest a default name (like yourname or org-name), but you can change it if you prefer.

Verify the region is correct.

Click Continue to create the organization.

Your Azure DevOps organization is now created. It’s the top-level container for all your projects.

Step 4: Create a Private Project Named Project1

In your Azure DevOps portal, find the " New Project " button and click it.

Enter the following details:

Project Name: Project1

Description: (optional)

Visibility: Private

Click Create.

A private project means that only users you add can see or access it. This is important for security and privacy.

Step 5: Enforce Maximum File Size for Repositories

By default, Azure DevOps allows files up to 100 MB to be pushed. To ensure the maximum file size for repositories in Project1 is 2 MB, you can enforce this using a pipeline validation.

Azure DevOps does not provide a direct setting for file size limits. However, you can create a pipeline to validate file size on pull requests and block changes if a file exceeds 2 MB.

Here’s how to do it:

Option 1: Enforce with a pipeline validation for pull requests

In your Project1, create a new pipeline.

Use the following YAML for the pipeline:

yaml

Copy

trigger: none

pr:

branches:

include:

- " * "

jobs:

- job: CheckFileSize

pool:

vmImage: ' ubuntu-latest '

steps:

- script: |

echo " Checking file sizes in the PR... "

git fetch origin +refs/pull/*/merge:refs/remotes/origin/pr/*

large_files=$(git diff --cached --name-only | xargs -I{} du -b {} | awk ' $1 > 2097152 {print $2} ' )

if [ -n " $large_files " ]; then

echo " Error: The following files exceed 2 MB: "

echo " $large_files "

exit 1

fi

displayName: ' Check file sizes in PR '

This pipeline will:

Run on pull requests only.

Check the size of all files in the pull request.

If any file is larger than 2 MB (2,097,152 bytes), it will fail the pipeline and block the PR.

Option 2: Local Git configuration (for each developer)

On each developer’s machine, run this command in their local repository:

bash

Copy

git config --local core.bigFileThreshold 2M

This limits the file threshold for checkout, but does not prevent large files from being pushed. Using the pipeline validation (Option 1) is more secure for team environments.

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.
