Question 1:
You need to configure GitHub to use Azure Active Directory (Azure AD) for authentication. What should you do first?
A. Create a conditional access policy in Azure AD.
B. Modify the Security settings of the GitHub organization.
C. Create an Azure Active Directory B2C (Azure AD B2C) tenant.
D. Register GitHub in Azure AD.
Correct Answer: D
When you connect to a Git repository from your Git client for the first time, the credential manager prompts for credentials. Provide your Microsoft account or Azure AD credentials.
Note: Git Credential Managers simplify authentication with your Azure Repos Git repositories. Credential managers let you use the same credentials that you use for the Azure DevOps Services web portal. Credential managers support multi-factor authentication through a Microsoft account or Azure Active Directory (Azure AD).
Besides supporting multi-factor authentication with Azure Repos, credential managers also support two-factor authentication with GitHub repositories.

How should you complete the command? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:
Correct Answer:
Explanation:
Box 1: checkout If you have deleted the file and already committed the changes, you need to use the `git checkout` command to restore the file. First, you need to find out the checksum of the commit that deleted the file, and then check out the file from the previous commit.
Box 2: –staged use “git restore –staged …” to unstaged
You need to run `git restore –staged –work tree `. The `–staged` argument tells `git` to restore the file in the index from HEAD, and the `–work tree` argument tells Git to restore the working tree as well.

Question 7:
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. Ansible
B. Maven
C. WhiteSource Bolt
D. Helm
Correct Answer: C
WhiteSource provides WhiteSource Bolt, a lightweight open-source security and management solution developed specifically for integration with Azure DevOps and Azure DevOps Server.
Note: WhiteSource is the leader in continuous open-source software security and compliance management. WhiteSource integrates into your build process, irrespective of your programming languages, build tools or development environments. It works automatically, continuously, and silently in the background, checking the security, licensing, and quality of your open-source components against WhiteSource’s constantly updated definitive database of open-source repositories.
Note: Blackduck would also be a good answer, but it is not an option here.
Reference: https://www.azuredevopslabs.com/labs/vstsextend/whitesource/
Question 8:
HOTSPOT
You have a project in Azure DevOps.
You plan to create a build pipeline that will deploy resources by using Azure Resource Manager templates. The templates will reference secrets stored in Azure Key Vault.
You need to ensure that you can dynamically generate the resource ID of the key vault during template deployment.
What should you include in the template? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:
Correct Answer:
Box 1: “Microsoft.Resources/deployments”
Reference a secret with dynamic ID. You need to reference a key vault secret that varies based on the current deployment.
Example:
“resources”: [
{
“apiVersion”: “2018-05-01”,
“name”: “dynamicSecret”,
“type”: “Microsoft.Resources/deployments”,
“properties”: {
“mode”: “Incremental”,
“template link”: {
Box 2: “Template link”
In your parent template, you add the linked template and pass in a parameter that contains the dynamically generated resource ID.

Question 10:
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.
1. Provide the ability to work on multiple independent tasks in parallel.
2. Ensure that the checked-in code remains in a releasable state always.
3. Ensure that new features can be abandoned at any time.
4. 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
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.
Reference: https://git-scm.com/book/en/v2/Git-Branching-Branching-Workflows
Question 11:
You need to execute inline testing of an Azure DevOps pipeline that uses a Docker deployment model. The solution must prevent the results from being published to the pipeline. What should you use for the inline testing?
A. a single stage Dockerfile
B. an Azure Kubernetes Service (AKS) pod
C. a multi-stage Dockerfile
D. a Docker Compose file
Correct Answer: B
Use Docker when running integration tests with Azure Pipelines.

Box 2: -ResourceType Reference: https://docs.microsoft.com/en-us/azure/azure-monitor/logs/manage-access
Question 13:
You have an existing project in Azure DevOps.
You plan to integrate GitHub as the repository for the project You need to ensure that Azure Pipelines runs under the Azure Pipelines identity Which authentication mechanism should you use?
A. GitHubApp
B. OAuth
C. personal access token (PAT)
D. Azure Active Directory (Azure AD)
Correct Answer: A
GitHub App uses the Azure Pipelines identity.
Reference: https://docs.microsoft.com/en-us/azure/devops/pipelines/repos/github
Question 14:
You use Azure Pipelines to build and release application code, The pipelines include validation tests that must be completed successfully before deployment proceeds from the test stage to production.
You discover inconsistent test outcomes for the same source code.
You need to validate the test logic.
What should you do?
A. Decrease the test pass rate.
B. Configure a parallel test runner.
C. Enable flaky test detection.
D. Install the Analytics extension.
Correct Answer: B
Question 15:
You intend to make use of Azure Artifacts to share packages that you wrote, tested, validated, and deployed.
You want to use a solitary feed to release several builds of each package. You have to make sure that the release of packages that are in development is restricted.
Which of the following actions should you take?
A. You should make use of static code analysis.
B. You should make use of views.
C. You should make use of dynamic code analysis.
D. You should make use of upstream sources.
Correct Answer: D
Upstream sources enable you to manage all of your product\’s dependencies in a single feed. We recommend publishing all of the packages for a given product to that product\’s feed, and managing that product\’s dependencies from remote feeds in the same feed, via upstream sources. This setup has a few benefits:
1. Simplicity: your NuGet.config, .npmrc, or settings.xml contains exactly one feed (your feed).
2. Determinism: your feed resolves package requests in order, so rebuilding the same codebase at the same commit or changeset uses the same set of packages
3. Provenance: your feed knows the provenance of packages it saved via upstream sources, so you can verify that you\’re using the original package, not a custom or malicious copy published to your feed
4. Peace of mind: packages used via upstream sources are guaranteed to be saved in the feed on first use; if the upstream source is disabled/removed, or the remote feed goes down or deletes a package you depend on, you can continue to develop and build
