Correct Answer:

Pass4itsure Microsoft az-400 exam questions q1-2

Box 1: Hosted macOS
Hosted macOS pool (Azure Pipelines only): Enables you to build and release on macOS without having to configure a
self-hosted macOS agent. This option affects where your data is stored.
Box 2: Hosted
Hosted pool (Azure Pipelines only): The Hosted pool is the built-in pool that is a collection of Microsoft-hosted agents.
Incorrect Answers:
Default pool: Use it to register self-hosted agents that you\\’ve set up.
Hosted Windows Container pool (Azure Pipelines only): Enabled you to build and release inside Windows containers.
Unless you\\’re building using containers, Windows builds should run in the Hosted VS2017 or Hosted pools.

virtual machines that run Windows Server 2016.
You need to recommend a deployment strategy for the virtual machines. The strategy must meet the following
requirements:
Ensure that the virtual machines maintain a consistent configuration.
Minimize administrative effort to configure the virtual machines

QUESTION 4
Your development team is building a new web solution by using the Microsoft Visual Studio integrated development
environment (IDE).
You need to make a custom package available to all the developers. The package must be managed centrally, and the
latest version must be available for consumption in Visual Studio automatically.
Which three actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
A. Publish the package to a feed.
B. Create a new feed in Azure Artifacts.
C. Upload a package to a Git repository.
D. Add the package URL to the Environment settings in Visual Studio.
E. Add the package URL to the NuGet Package Manager settings in Visual Studio.
F. Create a Git repository in Azure Repos.
Correct Answer: ABE
B: By using your custom NuGet package feed within your Azure DevOps (previously VSTS) instance, you\\’ll be able to
distribute your packages within your organization with ease. Start by creating a new feed.
A: We can publish, pack and push the built project to our NuGet feed.
E: Consume your private NuGet Feed
Go back to the Packages area in Azure DevOps, select your feed and hit “Connect to feed”. You\\’ll see some
instructions for your feed, but it\\’s fairly simple to set up.
Just copy your package source URL, go to Visual Studio, open the NuGet Package Manager, go to its settings and add
a new source. Choose a fancy name, insert the source URL. Done.
Search for your package in the NuGet Package Manager and it should appear there, ready for installation. Make sure to
select the appropriate feed (or just all feeds) from the top right select box.

Step 1: Kubectl create
You can add a service account to Tiller using the –service-account 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.

Pass4itsure Microsoft az-400 exam questions q13

In this example, a release of a website is created by collecting specific versions of two builds (artifacts), each from a
different build pipeline. The release is first deployed to a Dev stage and then forked to two QA stages in parallel. If the
deployment succeeds in both the QA stages, the release is deployed to Prod ring 1 and then to Prod ring 2. Each
production ring represents multiple instances of the same website deployed at various locations around the globe.
