Box 1: Azure Boards -
Azure Boards can be used to track work with Kanban boards, backlogs, team dashboards, and custom reporting
You can create multiple Trello boards, which are spaces to store tasks (for different work contexts, or even private boards)
You can easily share Trello boards with another person.
Box 2: Azure Pipelines -
You can use Bamboo to implement CI/CD (Continuous Integration and Continuous Delivery) for a simple Azure function app using Atlassian Bamboo. Bamboo does continuous delivery of the project from source code to deployment. It has stages including Build, Test and Deploy.
Software teams in every industry are upgrading their continuous delivery pipeline with Bamboo. Easy build import from popular open source tools, user and group import from JIRA, seamless integration with Bitbucket, and native support for Git, Hg, and SVN means you'll be building and deploying like a champ.
Box 3: GitHub repositories -
Bitbucket can be used as the Git repository, but you can use any other Git repository (Like TFS Git) for source control of the code.

Question 402

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.

Deployment 1: provisioner: kubernetes.io/azure-file
You can use Azure Files to connect using the Server Message Block (SMB) protocol.
Deployment 2: provisioner: kubernetes.io/azure-disk
Deployment 3: driver: secrets-store.csi.k8s.io
Azure Key vault provider for Secrets Store CSI driver allows you to access secrets stored in an Azure Key vault instance. The Secrets Store CSI driver secrets- store.csi.k8s.io allows the cluster to mount secrets stored in Azure Key vault into the pods as a volume.
Incorrect Answers:
blobfuse-flexvolume: This driver allows Kubernetes to access virtual filesystem backed by the Azure Blob storage.
Note: azurekeyvault-flexvolume has been deprecated and replaced by the Azure Key Vault Provider for Secret Store CSI Driver.

Question 407
You have a free tier of an Azure DevOps organization named Contoso. Contoso contains 10 private projects. Each project has multiple jobs with no dependencies.
You frequently run the jobs on five self-hosted agents but experience long build times and frequently queued builds.
You need to minimize the number of queued builds and the time it takes to run the builds.
What should you do?
A. Configure the pipelines to use the Microsoft-hosted agents.
B. Register additional self-hosted agents.
C. Purchase self-hosted parallel jobs.
D. Purchase Microsoft-hosted parallel jobs.
When the free tier is no longer sufficient, you can pay for additional capacity per parallel job.
Note: Microsoft-hosted CI/CD -
If you want to run your jobs on machines that Microsoft manages, use Microsoft-hosted parallel jobs. Your jobs run on our pool of Microsoft-hosted agents.
We provide a free tier of service by default in every organization.

Question 408
Your company uses Azure DevOps to manage the build and release processes for applications.
You use a Git repository for applications source control.
You plan to create a new branch from an existing pull request. Later, you plan to merge the new branch and the target branch of the pull request.
You need to use a pull request action to create the new branch. The solution must ensure that the branch uses only a portion of the code in the pull request.
Which pull request action should you use?
A. Set as default branch
B. Approve with suggestions
C. Cherry-pick
D. Reactivate
E. Revert
Cherry-pick a pull request -
To copy changes made in a pull request to another branch in your repo, follow these steps:
1. In a completed pull request, select Cherry-pick, or for an active pull request, select Cherry-pick from the ... menu. Cherry-picking a pull request in this way creates a new branch with the copied changes. Merge into a target branch in a second pull request.
2. In Target branch, enter the branch you want to merge the copied changes.
3. In Topic branch name, enter a new branch to contain the copied changes, then select Cherry-pick.
4. Select Create pull request to merge the topic branch into the target branch to complete the cherry-pick.

Each line in the .gitignore excludes a file or set of files that match a pattern.
Example:
# ignore a single file
Config.json -
Step 3: Run the git add .gitignore command
At the initial commit we want basically move from Untracked to Staged, for staging we have to indicate which file we want to move or specify a pattern, as example:

Question 410
You are designing a build pipeline in Azure Pipelines.
The pipeline requires a self-hosted agent. The build pipeline will run once daily and will take 30 minutes to complete.
You need to recommend a compute type for the agent. The solution must minimize costs.
What should you recommend?
A. an Azure Kubernetes Service (AKS) cluster
B. Azure Container Instances
C. an Azure virtual machine scale set
D. Azure virtual machines
If your pipelines are in Azure Pipelines, then you've got a convenient option to run your jobs using a Microsoft-hosted agent. With Microsoft-hosted agents, maintenance and upgrades are taken care of for you. Each time you run a pipeline, you get a fresh virtual machine. The virtual machine is discarded after one use.
Microsoft-hosted agents can run jobs directly on the VM or in a container.
Note: You can try a Microsoft-hosted agent for no charge.
