Case Study 1 - Litware 
Overview 
Existing Environment 
Litware, Inc. e an independent software vendor (ISV) Litware has a main office and five branch 
offices. 
 
QUESTION 1 
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.

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 approval process that contains a condition. The condition requires that releases be 
approved by a team leader before they are deployed. 
 
You have a poky stating that approvals must occur within eight hour. 
 
You discover that deployments fail if the approvals take longer than two hours. 
 
You need to ensure that the deployments only fail if the approvals take longer than eight hours. 
 
Solution: From Post-deployment conditions, you modify the Time between re-evaluation of gates 
option. 
 
Does this meet the goal? 
 
A. Yes 
B. No 
 
Answer: B 
Explanation: 
Use a gate From Pre-deployment conditions instead.

QUESTION 4 
You plan to create an image that will contain a .NET Core application. You have a Dockerfile file 
that contains the following code. (Line numbers are included for reference only.) 
 
 
 
You need to ensure that the image is as small as possible when the image is built. 
Which line should you modify in the file? 
 
A. 1 
B. 3 
C. 4 
D. 7 
 
 
Answer: A 
Explanation: 
Multi-stage builds (in Docker 17.05 or higher) allow you to drastically reduce the size of your final 
image, without struggling to reduce the number of intermediate layers and files. With multi-stage 
builds, you use multiple FROM statements in your Dockerfile. Each FROM instruction can use a 
different base, and each of them begins a new stage of the build. You can selectively copy 
artifacts from one stage to another, leaving behind everything you don't want in the final image.

QUESTION 5 
Your company has a hybrid cloud between Azure and Azure Stack. 
 
The company uses Azure DevOps for its CI/CD pipelines. Some applications are built by using 
Erlang and Hack. 
 
You need to ensure that Erlang and Hack are supported as part of the build strategy across the 
hybrid cloud. The solution must minimize management overhead. 
 
What should you use to execute the build pipeline? 
 
A. AzureDevOps self-hosted agents on Azure DevTest Labs virtual machines. 
B. AzureDevOps self-hosted agents on virtual machine that run on Azure Stack 
C. AzureDevOps self-hosted agents on Hyper-V virtual machines 
D. a Microsoft-hosted agent 
 
Answer: B 
Explanation: 
Azure Stack offers virtual machines (VMs) as one type of an on-demand, scalable computing 
resource. You can choose a VM when you need more control over the computing environment.

What should you use? 
 
A. Cobertura 
B. Bullseye Coverage 
C. MSTest 
D. Coverlet 
 
Answer: A 
Explanation:
