You have an Azure DevOps project named Project1 and an Azure subscriptionnamed Sub1. Sub1 contains an Azure virtual machine scale set named VMSS1. VMSS1 hosts a web application named WebApp1.
WebApp1 uses stateful sessions.
The WebApp1 installation is managed by using the Custom Script extension. The script resides in an AzureStorage account named sa1.
You plan to make a minor change to a UI element of WebApp1 and to gather user feedback about the change.
You need to implement limited user testing for the new version of WebApp1 on VMSS1.
Which three actions should you perform?Each correct answer presents part of the solution.
NOTE:Each correct selection is worth one point.

Explanation:
Step 1: Create a NuGet package.
NuGet and Maven are public package managers that support multiple feeds.
Step 2: Create an Azure Artifacts feed that uses upstream sources
If you want to use packages from multiple feeds, use upstream sources to bring packages from multiplefeeds together into a single feed.
Step 3: Create a Micrtosoft Visual Studio project that includes all the packages Consume NuGet packages from upstream sources: Now you can open Visual Studio and install packages from the upstream sources you just configured.

You plan to use Azure KubernetesService (AKS) to host containers deployed from images hosted in a Docker Trusted Registry.
You need to recommend a solution for provisioning and connecting to AKS. The solution must ensure that AKS is RBAC-enaWed and uses a custom service principal.
Whichthree 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 coned order.

Explanation:
Step 1 : az acr create
An Azure Container Registry (ACR) can alsobe created using the new Azure CLI.
az acr create
--name <REGISTRY_NAME>
--resource-group <RESOURCE_GROUP_NAME>
--sku Basic
Step 2: az ad sp create-for-rbac
Once the ACR has been provisioned, you can either enable administrative access (which is okay for testing) or you create a Service Principal (sp) which will provide a client_id and a client_secret.
az ad sp create-for-rbac
--scopes/subscriptions/<SUBSCRIPTION_ID>/resourcegroups/<RG_NAME>/providers/Microsoft.
ContainerRegistry/registries/<REGISTRY_NAME>
--role Contributor
--name <SERVICE_PRINCIPAL_NAME>
Step 3: kubectl create
Create a new Kubernetes Secret.
kubectl create secretdocker-registry <SECRET_NAME>
--docker-server <REGISTRY_NAME>.azurecr.io
--docker-email <YOUR_MAIL>
--docker-username=<SERVICE_PRINCIPAL_ID>
--docker-password <YOUR_PASSWORD>

You have an Azure subscription that contains a project in Azure DevOps named Project1. In Microsoft Azure Active Directory (Azure AD), part of MicrosoftEntra. you have three users that require access to Project! as shown in the following table.
You need to ensure that the users have the appropriate permissions. The solution must use the principle of least privilege.
To which permission group in AzureDevOps should you add each user? To answer, drag the appropriate permission groups to the correct users. Each permission group 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.

You use a Git repository in Azure Repos to manage the source code of a web application. Developers commit changes directly to the master branch.
You need to implement achange management procedure that meets the following requirements:
The master branch must be protected, and new changes must be built in the feature branches first.
Changes must be reviewed and approved by at least one release manager before each merge.
Changes must be brought into the master branch by using pull requests.
What should you configure in Azure Repos?
