QUESTION 1
DRAG DROP
You need to find and isolate shared code. The shared code will be maintained in a series of packages.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions
to the answer area and arrange them in the correct order.
Select and Place:
Correct Answer:
Step 1: Create a dependency graph for the application
By linking work items and other objects, you can track related work, dependencies, and changes made over time. All
links are defined with a specific link type. For example, you can use Parent/Child links to link work items to support a
hierarchical tree structure. Whereas, the Commit and Branch link types support links between work items and commits
and branches, respectively.
Step 2: Group the related components.
Packages enable you to share code across your organization: you can compose a large product, develop multiple
products based on a common shared framework, or create and share reusable components and libraries.
Step 3: Assign ownership to each component graph

QUESTION 5
Note: 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 integrate a cloud-hosted Jenkins server and a new Azure DevOps deployment.
You need Azure DevOps to send a notification to Jenkins when a developer commits changes to a branch in Azure
Repos.
Solution: You create an email subscription to an Azure DevOps notification.
Does this meet the goal?
A. Yes
B. No
Correct Answer: B
You can create a service hook for Azure DevOps Services and TFS with Jenkins.
References: https://docs.microsoft.com/en-us/azure/devops/service-hooks/services/jenkins
QUESTION 6
You have an Azure DevOps organization named Contoso, an Azure DevOps project named Project1, an Azure
subscription named Sub1, and an Azure key vault named vault1.
You need to ensure that you can reference the values of the secrets stored in vault1 in all the pipelines of Project1. The
solution must prevent the values from being stored in the pipelines.
What should you do?
A. Create a variable group in Project1.
B. Add a secure file to Project1.
C. Modify the security settings of the pipelines.
D. Configure the security policy of Contoso.
Correct Answer: A
Use a variable group to store values that you want to control and make available across multiple pipelines.
References: https://docs.microsoft.com/en-us/azure/devops/pipelines/library/variable-groups
QUESTION 7
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
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 8
Which branching strategy should you recommend for the investment planning applications suite?
A. release isolation
B. main only
C. development isolation
D. feature isolation
Correct Answer: C
Scenario: A branching strategy that supports developing new functionality in isolation must be used.
Feature isolation is a special derivation of the development isolation, allowing you to branch one or more feature
branches from main, as shown, or from your dev branches.
When you need to work on a particular feature, it might be a good idea to create a feature branch. Incorrect Answers:
A: Release isolation introduces one or more release branches from main. The strategy allows concurrent release
management, multiple and parallel releases, and codebase snapshots at release time.
B: The Main Only strategy can be folder-based or with the main folder converted to a Branch, to enable additional
visibility features. You commit your changes to the main branch and optionally indicate development and release
milestones with labels.
C: Development isolation: When you need to maintain and protect a stable main branch, you can branch one or more
dev branches from main. It enables isolation and concurrent development. Work can be isolated in development
branches by feature, organization, or temporary collaboration.

QUESTION 9
What should you use to implement the code quality restriction on the release pipeline for the investment planning
applications suite?
A. a pre-deployment approval
B. a deployment gate
C. a post-deployment approval
D. a trigger
Correct Answer: A
When a release is created from a release pipeline that defines approvals, the deployment stops at each point where
approval is required until the specified approver grants approval or rejects the release (or re-assigns the approval to
another
user).
Scenario: Code quality and release quality are critical. During release, deployments must not proceed between stages if
any active bugs are logged against the release.
References: https://docs.microsoft.com/en-us/azure/devops/pipelines/release/approvals/approvals
QUESTION 10
Your company uses Azure DevOps.
Only users who have accounts in Azure Active Directory can access the Azure DevOps environment.
You need to ensure that only devices that are connected to the on-premises network can access the Azure DevOps
environment.
What should you do?
A. Assign the Stakeholder access level all users.
B. In Azure Active Directory, configure risky sign-ins.
C. In Azure DevOps, configure Security in Project Settings.
D. In Azure Active Directory, configure conditional access.
Correct Answer: D
Conditional Access is a capability of Azure Active Directory. With Conditional Access, you can implement automated
access control decisions for accessing your cloud apps that are based on conditions.
Conditional Access policies are enforced after the first-factor authentication has been completed.
References:
https://docs.microsoft.com/en-us/azure/active-directory/conditional-access/overview
QUESTION 11
HOTSPOT
You need to configure a cloud service to store the secrets required by the mobile applications to call the share pricing
service.
What should you include in the solution? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:
Correct Answer:
Every request made against a storage service must be authorized, unless the request is for a blob or container resource
that has been made available for public or signed access. One option for authorizing a request is by using Shared Key.
Scenario: The mobile applications must be able to call the share pricing service of the existing retirement fund
management system. Until the system is upgraded, the service will only support basic authentication over HTTPS.
The investment planning applications suite will include one multi-tier web application and two iOS mobile application.
One mobile application will be used by employees; the other will be used by customers.

You plan to use hosted build agents.
Which build agent pool should you use to compile each application type? To answer, drag the appropriate build agent
pools to the correct application types. Each build agent pool 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:
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.

QUESTION 13
DRAG DROP You need to recommend project metrics for dashboards in Azure DevOps. Which chart widgets should
you recommend for each metric? To answer, drag the appropriate chart widgets to the correct metrics. Each chart
widget 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:
Box 1: Lead time
Lead time measures the total time elapsed from the creation of work items to their completion.
Box 2: Cycle time
Cycle time measures the time it takes for your team to complete work items once they begin actively working on them.
Box 3: Burndown
