Microsoft DevOps Engineer Expert AZ-400 Practice Question

You manage a GitHub Enterprise Cloud repository whose "Build-and-Test" workflow runs on every push. Product managers want to know which branches are least reliable and have asked for a visual that displays the workflow's success rate for each branch during the last seven days, available directly in the GitHub UI. Which action should you take in the repository to create this visualization?

  • Install a third-party GitHub Marketplace app for Actions analytics, configure branch filters in the app settings, and use the app's generated reliability dashboard.

  • Use the REST API endpoint /repos///actions/runs to retrieve the last week of runs, calculate success percentages offline, and embed a generated chart image in the repository README.

  • Enable Code scanning in Security, open the Security Insights dashboard, select the Build-and-Test workflow, and export a SARIF report for the last seven days.

  • Navigate to Actions > Performance Metrics, select New chart, choose the metric "Success rate", group by "Branch", filter on the Build-and-Test workflow, set the time range to Last 7 days, and save the chart.
