Exam Question 22
Your team uses an agile development approach.
You need to recommend a branching strategy for the team’s Git repository. The strategy must meet the following requirements:
- Provide the ability to work on multiple independent tasks in parallel.
- Ensure that checked-in code remains in a releasable state always.
- Ensure that new features can be abandoned at any time.
- Encourage experimentation.
What should you recommend?
A. a single long-running branch
B. multiple long-running branches
C. a single fork per team member
D. a single-running branch with multiple short-lived topic branches
Correct Answer:
D. a single-running branch with multiple short-lived topic branches
Answer Description:
Topic branches, however, are useful in projects of any size. A topic branch is a short-lived branch that you create and use for a single particular feature or related work. This is something you’ve likely never done with a VCS before because it’s generally too expensive to create and merge branches. But in Git it’s common to create, work on, merge, and delete branches several times a day.

Exam Question 24
You need to recommend an integration strategy for the build process of a Java application. The solution must meet the following requirements:
- The builds must access an on-premises dependency management system.
- The build outputs must be stored as Server artifacts in Azure DevOps.
- The source code must be stored in a Git repository in Azure DevOps.
Solution: Configure an Octopus Tentacle on an on-premises machine. Use the Package Application task in the build pipeline.
Does this meet the goal?
A. Yes
B. No
Correct Answer:
A. Yes
Answer Description:
Octopus Deploy is an automated deployment server that makes it easy to automate deployment of ASP.NET web applications, Java applications, NodeJS application and custom scripts to multiple environments.
Octopus can be installed on various platforms including Windows, Mac and Linux. It can also be integrated with most version control tools including VSTS and GIT.
When you deploy software to Windows servers, you need to install Tentacle, a lightweight agent service, on your Windows servers so they can communicate with the Octopus server.
When defining your deployment process, the most common step type will be a package step. This step deploys your packaged application onto one or more deployment targets.
When deploying a package you will need to select the machine role that the package will be deployed to.

Exam Question 28
Your company builds a multi-tier web application.
You use Azure DevOps and host the production application on Azure virtual machines.
Your team prepares an Azure Resource Manager template of the virtual machine that you will use to test new features.
You need to create a staging environment in Azure that meets the following requirements:
- Minimizes the cost of Azure hosting
- Provisions the virtual machines automatically
- Uses the custom Azure Resource Manager template to provision the virtual machines
What should you do?
A. In Azure Cloud Shell, run Azure CLI commands to create and delete the new virtual machines in a staging resource group.
B. In Azure DevOps, configure new tasks in the release pipeline to deploy to Azure Cloud Services.
C. From Azure Cloud Shell, run Azure PowerShell commands to create and delete the new virtual machines in a staging resource group.
D. In Azure DevOps, configure new tasks in the release pipeline to create and delete the virtual machines in Azure DevTest Labs.
Correct Answer:
D. In Azure DevOps, configure new tasks in the release pipeline to create and delete the virtual machines in Azure DevTest Labs.
Answer Description:
You can use the Azure DevTest Labs Tasks extension that’s installed in Azure DevOps to easily integrate your CI/CD build-and-release pipeline with Azure DevTest Labs. The extension installs three tasks:
- Create a VM
- Create a custom image from a VM
- Delete a VM
The process makes it easy to, for example, quickly deploy a “golden image” for a specific test task and then delete it when the test is finished.
