MultipleChoice

Your company has an on-premises Bitbucket Server that is used for Git-based source control. The server is protected by a firewall that blocks inbound Internet traffic.

You plan to use Azure DevOps to manage the build and release processes

Which two components are required to integrate Azure DevOps and Bitbucket?

Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one port.

Options

Aan External Git service connection

Ba Microsoft hosted agent

Cservice hooks

Da self- hosted agent

Ea deployment M group

Answer
A, DExplanation

When a pipeline uses a remote, 3rd-party repository host such as Bitbucket Cloud, the repository is configured with webooks that notify Azure Pipelines Server or TFS when code has changed and a build should be triggered. Since on-premises installations are normally protected behind a firewall, 3rd-party webhooks are unable to reach the on-premises server. As a workaround, you can use the External Git repository type which uses polling instead of webhooks to trigger a build when code has changed.

Dan Azure Active Directory (Azure AD) service principalD18912E1457D5D1DDCBD40AB3BF70D5D

Answer
BExplanation

The Azure Artifacts Credential Provider automates the acquisition of credentials needed torestore NuGet

packages as part of your .NET development workflow. It integrates with MSBuild, dotnet, and NuGet(.exe) and works on Windows, Mac, and Linux. Any time you want to use packages from an Azure Artifacts feed, the Credential Provider will automatically acquire and securely store a token on behalf of the NuGet client you're using.

You need to ensure that the https://contoso.com/statushook webhook is called every time a repository named az40038443478acr 1 receives a new version of an image named dotnetapp

Options

ASee the solution below in explanation

Answer
AExplanation

To ensure that the webhook at https://contoso.com/statushook is called every time the repository named az40038443478acr1 receives a new version of an image named dotnetapp, you can follow these steps to configure a webhook in Azure Container Registry:

Navigate to the Azure Container Registry:

Go to the Azure Portal.

Find and select your Azure Container Registry instance az40038443478acr1.

Create a New Webhook:

Under Services, select Webhooks.

Click on + Add to create a new webhook.

Fill in the form with the following information:

Webhook name: Enter a unique name for your webhook.

Service URI: Enter https://contoso.com/statushook.

Custom headers: (Optional) Add any headers you want to pass along with the POST request.

Trigger actions: Select Push to trigger the webhook on image push events.

Scope: Specify the scope as az40038443478acr1:dotnetapp to target the specific image.

Status: Set to Enabled.

Save the Webhook Configuration:

Review the information and click Create to save the webhook.

Once configured, the webhook will send a POST request to https://contoso.com/statushook whenever a new version of the dotnetapp image is pushed to the az40038443478acr1 repository in your Azure Container Registry1.

This setup will automate the notification process, ensuring that the specified webhook is called with each new image version, thus fulfilling the task requirements.
