The test servers are configured correctly when first deployed, but they experience 
configuration drift over time. Azure Automation State Configuration fails to correct the 
configurations. 
Azure Automation State Configuration nodes are registered by using the following 
command. 
 
 
Question: 1 
   
   
How should you complete the code to initialize App Center in the mobile application? To answer, select 
the appropriate options in the answer area. 
NOTE: Each correct selection a worth one point. 
 
Answer:  
 
Explanation: 
Scenario: Visual Studio App Center must be used to centralize the reporting of mobile application 
crashes and device types in use. 
In order to use App Center, you need to opt in to the service(s) that you want to use, meaning by default 
no services are started and you will have to explicitly call each of them when starting the SDK. 
 
Insert the following line to start the SDK in your app's AppDelegate class in the 
didFinishLaunchingWithOptions method. 
MSAppCenter.start("{Your App Secret}", withServices: [MSAnalytics.self, MSCrashes.self])

Question: 2 
How should you confrere the release retention policy for the investment planning depletions suite? To 
answer, select the appropriate options in the answer area. 
NOTE: Each correct selection is worth one point. 
 
Answer:  
 
Explanation: 
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.

Question: 3 
You need to configure a cloud service to store the secrets required by the mobile applications to call the 
share. 
What should you include in the solution? To answer, select the appropriate options m the answer ate»,

Question: 4 
 
To resolve the current technical issue, what should you do to the Register-AzureRmAutomationDscNode 
command? 
 
A. Change the value of the ConfigurationMode parameter. 
B. Replace the Register-AzureRmAutomationDscNode cmdlet with 
Register-AzureRmAutomationScheduledRunbook 
C. Add the AllowModuleOverwrite parameter. 
D. Add the DefaultProfile parameter. 
 
Answer: A         
 
Explanation: 
Change the ConfigurationMode parameter from ApplyOnly to ApplyAndAutocorrect. 
The Register-AzureRmAutomationDscNode cmdlet registers an Azure virtual machine as an APS Desired 
State Configuration (DSC) node in an Azure Automation account. 
Scenario: Current Technical Issue 
The test servers are configured correctly when first deployed, but they experience configuration drift 
over time. Azure Automation State Configuration fails to correct the configurations. 
Azure Automation State Configuration nodes are registered by using the following command.

Question: 5 
   
   
What should you use to implement the code quality restriction on the release pipeline for the 
investment planning applications suite? 
 
A.  a trigger 
B.  a pre deployment approval 
C.  a post-deployment approval 
D.  a deployment gate 
 
 
Answer: B         
 
Explanation: 
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.

Question: 6 
   
   
How should you configure the release retention policy for the investment planning applications suite? 
To answer, select the appropriate options in the answer area. 
NOTE: Each correct selection is worth one point. 
 
Answer:  
 
 
Explanation: 
Scenario: By default, all releases must remain available for 30 days, except for production releases, 
which must be kept for 60 days. 
Box 1: Set the default retention policy to 30 days 
The Global default retention policy sets the default retention values for all the build pipelines. Authors 
of build pipelines can override these values. 
Box 2: Set the stage retention policy to 60 days 
You may want to retain more releases that have been deployed to specific stages.

Question: 7 
 
Where should the build and release agents for the investment planning application suite run? To 
answer, select the appropriate options in the answer area. 
NOTE: Each correct selection is worth one point. 
 
Answer:  
 
 
Explanation: 
Box 1: A source control system 
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. 
Box 2: A hosted service 
To build and deploy Xcode apps or Xamarin.iOS projects, you'll need at least one macOS agent. If your 
pipelines are in Azure Pipelines and a Microsoft-hosted agent meets your needs, you can skip setting up 
a self-hosted macOS agent. 
Scenario: The investment planning applications suite will include one multi-tier web application and two 
iOS mobile applications. One mobile application will be used by employees; the other will be used by 
customers.

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 
 
Answer: C         
 
Explanation: 
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 
   
   
Which package feed access levels should be assigned to the Developers and Team Leaders groups for 
the investment planning applications suite? To answer, drag the appropriate access levels to the correct 
groups. Each access level 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.
