AZ-400 Microsoft Azure DevOps Solutions exams demo

You are developing a multi-tier application. The application will use Azure App Service web apps as the front
end and an Azure SQL database as the back end. The application will use Azure functions to write some data
to Azure Storage.
You need to send the Azure DevOps team an email message when the front end fails to return a status code of
200.
Which feature should you use?
A. Service Map in Azure Log Analytics
B. Availability tests in Azure Application Insights
C. Profiler in Azure Application Insights
D. Application Map in Azure Application Insights
Correct Answer: D
Section: (none)
Explanation
Explanation/Reference:
Explanation:
Application Map helps you spot performance bottlenecks or failure hotspots across all components of your
distributed application. Each node on the map represents an application component or its dependencies; and
has health KPI and alerts status.
Incorrect Answers:
A: Service Map automatically discovers application components on Windows and Linux systems and maps the
communication between services. You can use it to view your servers as you think of them--interconnected
systems that deliver critical services. Service Map shows connections between servers, processes, and ports
across any TCP-connected architecture with no configuration required, other than installation of an agent.

Section: (none)
Explanation
Explanation/Reference:
Explanation:
PMD is a source code analyzer. It finds common programming flaws like unused variables, empty catch
blocks, unnecessary object creation, and so forth.
There is an Apache Maven PMD Plugin which allows you to automatically run the PMD code analysis tool on
your project's source code and generate a site report with its results.
Incorrect Answers:
C: xcpretty is a fast and flexible formatter for xcodebuild.

QUESTION 8
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 point.
A. a deployment group
B. a Microsoft-hosted agent
C. service hooks
D. a self-hosted agent
E. an External Git service connection
Correct Answer: DE
Section: (none)
Explanation
Explanation/Reference:
Explanation:
E: GitLab CI/CD can be used with GitHub or any other Git server such as BitBucket. Instead of moving your
entire project to GitLab, you can connect your external repository to get the benefits of GitLab CI/CD.
Note: When a pipeline uses a remote, 3rd-party repository host such as Bitbucket Cloud, the repository is
configured with webhooks 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.

QUESTION 9
Your company plans to use an agile approach to software development.
You need to recommend an application to provide communication between members of the development team
who work in locations around the world. The applications must meet the following requirements:
Provide the ability to isolate the members of different project teams into separate communication channels
and to keep a history of the chats within those channels.
96CE4376707A97CE80D4B1916F054522
Be available on Windows 10, Mac OS, iOS, and Android operating systems.
Provide the ability to add external contractors and suppliers to projects.
Integrate directly with Azure DevOps.
What should you recommend?
A. Skype for Business
B. Bamboo
C. Octopus
D. Slack
Correct Answer: D
Section: (none)
Explanation
Explanation/Reference:
Explanation:
Slack is a popular team collaboration service that helps teams be more productive by keeping all
communications in one place and easily searchable from virtually anywhere. All your messages, your files, and
everything from Twitter, Dropbox, Google Docs, Azure DevOps, and more all together. Slack also has fully
native apps for iOS and Android to give you the full functionality of Slack wherever you go.
Integrated with Azure DevOps
This integration keeps your team informed of activity happening in its Azure DevOps projects. With this
integration, code check-ins, pull requests, work item updates, and build events show up directly in your team's
Slack channel.
Note: Microsoft Teams would also be a correct answer, but it is not an option here.

QUESTION 11
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
Section: (none)
Explanation
Explanation/Reference:
Explanation:
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.

authentication.
You need to ensure that the project can restore the NuGet package automatically.
What should the project use to automate the authentication?
A. an Azure Automation account
B. an Azure Artifacts Credential Provider
C. an Azure Active Directory (Azure AD) account that has multi-factor authentication (MFA) enabled
D. an Azure Active Directory (Azure AD) service principal

The Azure Artifacts Credential Provider automates the acquisition of credentials needed to restore 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.
