Your company has an on-premises Bitbucket Server that is used for Git-based source control. The server is protected by a firewall that blocks inbound Internet traffic.
You plan to use Azure DevOps to manage the build and release processes Which two components are required to integrate Azure DevOps and Bitbucket? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one port.

1. A. an External Git service connection
2. B. a Microsoft hosted agent
3. C. service hooks
4. D. a self- hosted agent
5. E. a deployment M group

Correct Answer: AD
When a pipeline uses a remote, 3rd-party repository host such as Bitbucket Cloud, the repository is configured with webhooks that notify Azure Pipelines Server or TFS when code has changed and a build should be triggered. Since on-premises installations are normally protected behind a firewall, 3rd-party webhooks are unable to reach the on-premises server. As a workaround, you can use the External Git repository type which uses polling instead of webhooks to trigger a build when code has changed.

You have an Azure DevOps organization named Contoso.
You need to recommend an authentication mechanism that meets the following requirements:
• Supports authentication from Git
• Minimizes the need to provide credentials during authentication What should you recommend?

1. A. managed identities in Azure Active Directory (Azure AD)
2. B. personal access tokens (PATs) in Azure DevOps
3. C. user accounts in Azure Active Directory (Azure AD)
4. D. Alternate credentials in Azure DevOps

Correct Answer: B
Personal access tokens (PATs) give you access to Azure DevOps and Team Foundation Server (TFS), without using your username and password directly. These tokens have an expiration date from when they're created. You can restrict the scope of the data they can access. Use PATs to authenticate if you don't already have SSH keys set up on your system or if you need to restrict the permissions that are granted by the credential.

You are evaluating the use of code review assignments in GitHub.
Which two requirements can be met by using code review assignments' Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point

1. A. Automatically choose and assign reviewers based on a list of available personnel
2. B. Automatically choose and assign reviewers based on who has the most completed review requests.
3. C. Ensure that each team member reviews an equal number of pull requests during any 30-day period.
4. D. Automatically choose and assign reviewers based on who received the least recent review requests.

Correct Answer: AC

You have a private GitHub repository.
You need to display the commit status of the repository on Azure Boards.
What should you do first?

1. A. Create a GitHub action in GitHub.
2. B. Add the Azure Pipelines app to the GitHub repository.
3. C. Configure multi-factor authentication (MFA) for your GitHub account.
4. D. Add the Azure Boards app to the repository.

Correct Answer: D
To connect Azure Boards to GitHub.com, connect and configure from Azure Boards. Or, alternatively, install and configure the Azure Boards app from GitHub. Both methods have been streamlined and support authenticating and operating via the app rather than an individual.
Note (see step 4 below): Add a GitHub connection:
Sign into Azure Boards.
Choose (1) Project Settings, choose (2) GitHub connections and then (3) Connect your GitHub account.
If this is your first time connecting to GitHub from Azure Boards, you will be asked to sign in using your GitHub credentials. Choose an account for which you are an administrator for the repositories you want to connect to.
The Add GitHub Repositories dialog automatically displays and selects all GitHub.com repositories for which you are an administrator. Unselect any repositories that you don't want to participate in the integration.

You are configuring the settings of a new Git repository in Azure Repos.
You need to ensure that pull requests in a branch meet the following criteria before they are merged:
Committed code must compile successfully.
Pull requests must have a Quality Gate status of Passed in SonarCloud.
Which policy type should you configure for each requirement? To answer, drag the appropriate policy types to the correct requirements. Each policy type may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

Solution:
Box 1: A check-in policy
Administrators of Team Foundation version control can add check-in policy requirements. These check-in policies require the user to take actions when they conduct a check-in to source control.
By default, the following check-in policy types are available:
Builds Requires that the last build was successful before a check-in.
Code Analysis Requires that code analysis is run before check-in.
Work Items Requires that one or more work items be associated with the check-in. Box 2: Build policy
