NEW QUESTION # 161
You have an Azure DevOps project that contains a release pipeline and a Git repository.
When a new code revision is committed to the repository, a build and release is triggered.
You need to ensure that release information for the pipeline is added automatically to the work items associated to the Get commit.
What should you do?
- A. Modify the Integrations options for the pipeline.
- B. Modify the service hooks for the project.
- C. Modify the post-deployment conditions for the last stage of the pipeline.
- D. Add an agentless job to the pipeline.
Answer: A
Explanation:
Service hooks in Azure DevOps allow you to trigger actions in other tools based on events that occur in your Azure DevOps project. To automatically add release information to work items associated with a Get commit, you would need to configure a service hook that listens for commit events in your Get repository, and then sends the release information to the appropriate work items.
Here's the steps you can follow to set up a service hook for this purpose:
In your Azure DevOps project, navigate to the project settings by clicking on the gear icon in the top right corner of the page.
Select "Service Hooks" from the left-hand menu.
Click on the "New Subscription" button to create a new service hook.
In the "Event" drop-down menu, select "Code pushed" to trigger the service hook when a new code revision is committed to the repository.
In the "Actions" section, select the action that you want to take place when the service hook is triggered.
For example, you might use the "Link work items to commits" action to automatically associate work items with the relevant commits.
Configure the remaining settings as needed, and then click on the "Create" button to create the service hook.
You can find more information on Service hooks in Azure DevOps by following this link

NEW QUESTION # 169
You provision an Azure Kubernetes Service (AKS) cluster that has RBAC enabled. You have a Helm chart for a client application.
You need to configure Helm and Tiller on the cluster and install the chart.
Which three commands should you recommend be run in sequence? To answer, move the appropriate commands from the list of commands to the answer area and arrange them in the correct order.
Answer:
Explanation:
Explanation
Step 1: Kubectl create
You can add a service account to Tiller using the --service-account <NAME> flag while you're configuring Helm (step 2 below). As a prerequisite, you'll have to create a role binding which specifies a role and a service account name that have been set up in advance.
Example: Service account with cluster-admin role
$ kubectl create -f rbac-config.yaml
serviceaccount "tiller" created
clusterrolebinding "tiller" created
$ helm init --service-account tiller
Step 2: helm init
To deploy a basic Tiller into an AKS cluster, use the helm init command.
Step 3: helm install
To install charts with Helm, use the helm install command and specify the name of the chart to install.

NEW QUESTION # 170
You have an Azure DevOps project that contains a build pipeline. The build pipeline uses approximately 50 open source libraries.
You need to ensure that all the open source libraries comply with your company's licensing standards.
Which service should you use?
- A. NuGet
- B. Maven
- C. Black Duck
- D. Helm
Answer: C
Explanation:
Secure and Manage Open Source Software
Black Duck helps organizations identify and mitigate open source security, license compliance and code-quality risks across application and container portfolios.
Black Duck Hub and its plugin for Team Foundation Server (TFS) allows you to automatically find and fix open source security vulnerabilities during the build process, so you can proactively manage risk. The integration allows you to receive alerts and fail builds when any Black Duck Hub policy violations are met.
Note: WhiteSource would also be a good answer, but it is not an option here.

NEW QUESTION # 171
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 fork per team member
- B. multiple long-running branches
- C. a single long-running branch
- D. a single-running branch with multiple short-lived topic branches
Answer: D
Explanation:
Explanation
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.
