NO.95 You need to implement Project6.
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 them m the correct order.

Explanation

Scenario: Implement Project3, Project5, Project6, and Project7 based on the planned changes

Step 1: Open the release pipeline editor.
In the Releases tab of Azure Pipelines, select your release pipeline and choose Edit to open thepipeline editor.
Step 2: Enable Gates.
Choose the pre-deployment conditions icon for the Production stage to open the conditions panel. Enable gates by using the switch control in the Gates section.
Step 3: Add Query Work items.
Choose + Add and select the Query Work Items gate.
Configure the gate by selecting an existing work item query.

Note: A case for release gate is:
Incident and issues management. Ensure the required status for work items, incidents, and issues. For example, ensure deployment occurs only if no priority zero bugs exist, and validation that there are no active incidents takes place after deployment.

NO.97 In Azure DevOps, you create Project3.
You need to meet the requirements of the project.
What should you do first?

From Azure DevOps, create a service endpoint.

From SonarQube, obtain an authentication token.

From Azure DevOps, modify the build definition.

From SonarQube, create a project.

The first thing to do is to declare your SonarQube server as a service endpoint in your VSTS/DevOps project settings.

NO.98 You have an Azure DevOps project that contains a release pipeline and a Git repository.
When a new code revision is committed to the repository, a build and release is triggered.
You need to ensure that release information for the pipeline is added automatically to the work items associated to the Get commit.
What should you do?

Modify the Integrations options for the pipeline.

Modify the post-deployment conditions for the last stage of the pipeline.

Add an agentless job to the pipeline.

Modify the service hooks for the project.

Explanation
Service hooks in Azure DevOps allow you totrigger actions in other tools based on events that occur in your Azure DevOps project. To automatically add release information to work items associated with a Get commit, you would need to configure a service hook that listens for commit events in yourGet repository, and then sends the release information to the appropriate work items.
Here’s the steps you can follow to set up a service hook for this purpose:
* In your Azure DevOps project, navigate to the project settings by clicking on the gear iconin the top right corner of the page.
* Select “Service Hooks” from the left-hand menu.
* Click on the “New Subscription” button to create a new service hook.
* In the “Event” drop-down menu, select “Code pushed” to trigger the service hook when a new code revision is committed to the repository.
* In the “Actions” section, select the action that you want to take place when the service hook is triggered.
For example, you might use the “Link work items to commits” action to automatically associate work items with therelevant commits.
* Configure the remaining settings as needed, and then click on the “Create” button to create the service hook.
You can find more information on Service hooks in Azure DevOps by following this linkhttps://docs.microsoft.com/en-us/azure/devops/service-hooks/overview?view=azure-devops

NO.99 Your company plans to deploy an application to the following endpoints:
* Ten virtual machines hosted in Azure
* Ten virtual machines hosted in an on-premises data center environment All the virtual machines have the Azure Pipelines agent.
You need to implement a release strategy for deploying the application to the endpoints.
What should you recommend using to deploy the application to the endpoints? To answer, drag the appropriate components to the correct endpoints. Each component may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

Explanation

Box 1: A deployment group
When authoring an Azure Pipelines or TFS Release pipeline, you can specify the deployment targets for a job using a deployment group.
If the target machines are Azure VMs, you can quickly and easily prepare them by installing the Azure Pipelines Agent Azure VM extension on each of the VMs, or by using the Azure Resource Group Deployment task in your release pipeline to create a deployment group dynamically.

Which four actions should you perform in sequence? To answer, move the appropriate actions from the List of actions to the answer area and arrange them in the correct order.

Explanation

Step 1: Create an agent pool
Azure Pipelines provides a pre-defined agent pool named Azure Pipelines with Microsoft-hosted agents.
Step 2: Create a deployment group
Deployment groups make it easy to define logical groups of target machines for deployment, and install the required agent on each machine.
Step 3: Execute the Azure Pipelines Agent extension to the virtual machines Install the Azure Pipelines Agent Azure VM extension Step 4: Add and configure a deployment group job for the pipeline Tasks that you define in a deployment group job run on some or all of the target servers, depending on the arguments you specify for the tasks and the job itself.
