Microsoft Microsoft Certifications AZ-400 Questions & Answers

• Question 201:

  You manage a project by using Azure Board, and you manage the project code by using Azure Repos.

  You have a bug work item that has an ID of 123.

  You need to set the work item state to Resolved.

  What should you add to the commit message?

  A. #123 completes

  B. Resolves #AB-123

  C. Verifies #123

  D. Fixes #123

  Correct Answer: D

  Resolve work items on commit

  Close work items by mentioning keywords in commit messages. When you mention a work item in a commit that makes it to the default branch via one of the supported workflows, we will attempt to resolve that work item.

  Keywords

  The three supported keywords to trigger a resolution mention are fix, fixes, and fixed (case insensitive). Optionally, a colon can follow the keyword. Most forms of punctuation can precede or proceed the resolution mention, excluding another

  pound sign (#).

  Examples

  Fixes #123

  This fixed #123!

  Change behavior to fix: #123

  Fixes #123 and fixes #124

• Question 202:

  You manage projects by using Azure Boards.

  You have a current work item name itemA that is dependant on a work item named itemB.

  You need to define the dependency for itemA.

  What should you do in the web portal for Azure DevOps?

  A. Add a Parent link to the user story of itemA.

  B. From Backlogs, open the context menu, select Add link, and then select itemA. Set Link type to References and add the ID of itemB.

  C. From itemA, open the Links tab, and then select Add link. Set Link type to References and add the ID of itemB.

  D. From itemA, open the Links tab, and then select Add link. Set Link type to Successor and add the ID of itemB.

  Correct Answer: D

  Dependencies can be created from the Links Tab Dependencies can be created using the Predecessor and Successor links on the Links tab. A predecessor is the producer of the work item, or the item that must come first. A successor is the consumer of the work item, or the item that is dependent on the first item.

  Create a service hook for Azure DevOps with Slack Step 1: Create a custom app in Slack Step 2: Create a service hook subscription in your organization

  1.

  Go to your project Service Hooks page. https://{orgName}/{project_name}/_settings/serviceHooks

  2.

  Choose the types of events you want to appear in your Slack channel.

  You can filter each of the triggers in specific ways. For example, filter the pull request created trigger on the repository in which the pull request occurs, the target branch it applies to, and the team members required or invited to review the request.

  3.

  Paste the Web Hook URL from the Slack integration that you created (in Step 1 above) and select Finish.

  When the event occurs in your project, a notification appears in your team's Slack channel.

• Question 207:

  You have the services shown in the following table.

  

  You manage a project by using Azure Boards.

  You need to notify the services of build status changes.

  Which services can be notified by using a webhook?

  A. Service1 only

  B. Service2 only

  C. Service1 and Service2

  Correct Answer: C

  Webhooks provide a way to send a JSON representation of an event to any service. All that is required is a public endpoint (HTTP or HTTPS).

  Q: Can I send webhooks to non HTTPS endpoints?

  A: Yes. However, it's recommended that you only use HTTPS endpoints for your webhooks. Using HTTP means there is the potential for private data being sent unencrypted. This includes any authentication headers in your webhook.

• Question 208:

  You manage a project by using Azure Boards. You manage the project code by using GitHub.

  You have three work items that have IDs of 456, 457, and 458.

  You need to create a pull request that will be linked to all the work items. The solution must set the state of work item 456 to done.

  What should you add to the commit message?

  A. #AB456, #AB457, #AB458Completed #AB456

  B. #456, #457, #458Completed #456

  C. Done #AB456, #AB457, #AB458

  D. #AB456, #AB457, #AB458Verifies #AB456

  Correct Answer: A

  Use the #AB{id} syntax for the work items.

  Use Completed #AB456 to set the state of work item 456 to done.

  Note: Use AB# mention to link from GitHub to Azure Boards work items

  From a GitHub commit, pull request or issue, use the following syntax to create a link to your Azure Boards work item. Enter the AB#ID within the text of a commit message. Or, for a pull request or issue, enter the AB#ID within the title or

  description (not a comment).

  AB#{ID}

  For example, AB#125 will link to work item ID 125.

  You can also enter a commit or pull request message to transition the work item. The system will recognize fix, fixes, fixed and apply it to the #-mention item that follows.

  Example:

  Fixes AB#123, AB#124, and AB#126

  Links to Azure Boards work items 123, 124, and 126. Transitions only the first item, 123 to the Resolved workflow state category or, if none is defined, then the Completed workflow state category.
