QUESTION 10
DRAG DROP
You are configuring Azure Pipelines for three projects in Azure DevOps as shown in the following table.

Which version control system should you recommend for each project? To answer, drag the appropriate version control
systems to the correct projects. Each version control system 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:

Correct Answer:

Project1:Git in Azure Repos
Project2: Github Enterprise
GitHub Enterprise is the on-premises version of GitHub.com. GitHub Enterprise includes the same great set of features
as GitHub.com but packaged for running on your organization\\’s local network. All repository data is stored on
machines
that you control, and access is integrated with your organization\\’s authentication system (LDAP, SAML, or CAS).
Project3: Bitbucket cloud
One downside, however, is that Bitbucket does not include support for SVN but this can be easily amended by migrating
the SVN repos to Git with tools such as SVN Mirror for Bitbucket.
Note: SVN is a centralized version control system.
Incorrect Answers:
Bitbucket:
Bitbucket comes as a distributed version control system based on Git.
Note: A source control system, also called a version control system, allows developers to collaborate on code and track
changes. Source control is an essential tool for multi-developer projects.
Our systems support two types of source control: Git (distributed) and Team Foundation Version Control (TFVC). TFVC
is a centralized, client-server system. In both Git and TFVC, you can check-in files and organize files in folders,
branches,
and repositories.

QUESTION 12
This question is part of a series of questions that present the same scenario. Each question in the series contains a
unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while
others
might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not
appear in the review screen.
You have an Azure DevOps project.
Your build process creates several artifacts.
You need to deploy the artifacts to on-premises servers.
Solution: You deploy an Azure self-hosted agent to an on-premises server. You add a Copy and Publish the Build Artifacts task to the deployment pipeline.
Does this meet the goal?
A. Yes
B. No
Correct Answer: A
To build your code or deploy your software using Azure Pipelines, you need at least one agent.
If your on-premises environments do not have connectivity to a Microsoft-hosted agent pool (which is typically the case
due to intermediate firewalls), you\\’ll need to manually configure a self-hosted agent on the on-premises computer(s). The
agents must have connectivity to the target on-premises environments, and access to the Internet to connect to Azure
Pipelines or Team Foundation Server.
References: https://docs.microsoft.com/en-us/azure/devops/pipelines/agents/agents?view=azure-devops

QUESTION 13
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:
1.
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.
2.
Be available on Windows 10, Mac OS, iOS, and Android operating systems.
3.
Provide the ability to add external contractors and suppliers to projects.
4.
Integrate directly with Azure DevOps. What should you recommend?
A. Microsoft Project
B. Bamboo
C. Microsoft Lync
D. Microsoft Teams
E. Octopus
Correct Answer: D
1.
Within each team, users can create different channels to organize their communications by topic. Each channel can
include a couple of users or scale to thousands of users.
2.
Microsoft Teams works on Android, iOS, Mac, and Windows systems and devices. It also works in Chrome, Firefox,
Internet Explorer 11 and Microsoft Edge web browsers.
3.
The guest-access feature in Microsoft Teams allows users to invite people outside their organizations to join internal
channels for messaging, meetings, and file sharing. This capability helps to facilitate business-to-business project
management.
4.
Teams integrate with Azure DevOps.
Note: Slack would also be a correct answer, but it is not an option here.
