DRAG DROP (Drag and Drop is not supported)
You provision an Azure Kubernetes Service (AKS) cluster that has RBAC enabled. You have a Helm chart for a client application. You need to configure Helm and Tiller on the cluster and install the chart.
Which three commands should you recommend be run in sequence? To answer, move the appropriate commands from the list of commands to the answer area and arrange them in the correct order.
Select and Place:

  1. See Explanation section for answer.

Answer(s): A

Explanation:




Step 1: Kubectl create
You can add a service account to Tiller using the --service-account <NAME> flag while you’re configuring Helm (step 2 below). As a prerequisite, you’ll have to create a role binding which specifies a role and a service account name that have been set up in advance.
Example: Service account with cluster-admin role
$ kubectl create -f rbac-config.yaml
serviceaccount "tiller" created
clusterrolebinding "tiller" created
$ helm init --service-account tiller

Step 2: helm init
To deploy a basic Tiller into an AKS cluster, use the helm init command.

Step 3: helm install
To install charts with Helm, use the helm install command and specify the name of the chart to install.

Your company builds a multi-tier web application.
You use Azure DevOps and host the production application on Azure virtual machines.

Your team prepares an Azure Resource Manager template of the virtual machine that you will use to test new features. You need to create a staging environment in Azure that meets the following requirements:
-Minimizes the cost of Azure hosting
-Provisions the virtual machines automatically
-Uses the custom Azure Resource Manager template to provision the virtual machines

What should you do?

  1. In Azure Cloud Shell, run Azure CLI commands to create and delete the new virtual machines in a staging resource group.
  2. In Azure DevOps, configure new tasks in the release pipeline to deploy to Azure Cloud Services.
  3. From Azure Cloud Shell, run Azure PowerShell commands to create and delete the new virtual machines in a staging resource group.
  4. In Azure DevOps, configure new tasks in the release pipeline to create and delete the virtual machines in Azure DevTest Labs.

Answer(s): D

Explanation:

You can use the Azure DevTest Labs Tasks extension that's installed in Azure DevOps to easily integrate your CI/CD build-and-release pipeline with Azure DevTest Labs. The extension installs three tasks:
Create a VM
Create a custom
image from a VM
Delete a VM

The process makes it easy to, for example, quickly deploy a "golden image" for a specific test task and then delete it when the test is finished.

DRAG DROP (Drag and Drop is not supported)
You are implementing an Azure DevOps strategy for mobile devices using App Center. You plan to use distribution groups to control access to releases.
You need to create the distribution groups shown in the following table.


Which type of distribution group should you use for each group? To answer, drag the appropriate group types to the correct locations. Each group type 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.
Select and Place:

  1. See Explanation section for answer.

Answer(s): A

Explanation:


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.


Reference:

https://docs.microsoft.com/en-us/appcenter/distribution/groups



SIMULATION
You need to ensure that the https://contoso.com/statushook webhook is called every time a repository named az40010480345acr1 receives a new version of an image named dotnetapp.
To complete this task, sign in to the Microsoft Azure portal.

  1. See Explanation section for answer.

Answer(s): A

Explanation:

1.Sign in to the Azure portal.
2.Navigate to the container registry az40010480345acr1.
3.Under Services, select Webhooks.
4.Select the existing webhook https://contoso.com/statushook, and double-click on it to get its properties.
5.For Trigger actions select image push

Example web hook:


Reference:

https://docs.microsoft.com/en-us/azure/container-registry/container-registry-webhook



HOTSPOT (Drag and Drop is not supported)
You need to create deployment files for an Azure Kubernetes Service (AKS) cluster. The deployments must meet the provisioning storage requirements shown in the following table.


Which resource type should you use for each deployment? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:




Deployment 1: Kubernetes.io/azure-file
You can use Azure Files to connect using the Server Message Block (SMB) protocol.

Deployment 2: Kubernetes.io/azure-disk

Deployment 3: azurekeyvault-flexvolume
azurekeyvault-flexvolume: Key Vault FlexVolume: Seamlessly integrate your key management systems with Kubernetes.
Secrets, keys, and certificates in a key management system become a volume accessible to pods. Once the volume is mounted, its data is available directly in the container filesystem for your application.

Incorrect Answers:
blobfuse-flexvolume: This driver allows Kubernetes to access virtual filesystem backed by the Azure Blob storage.
