  Sprint retrospective meetings The sprint retrospective meeting typically occurs on the last day of the sprint, after the sprint review meeting. In this meeting, your team explores its execution of Scrum and what might need tweaking. Based on discussions, your team might decide to change one or more processes to improve its own effectiveness, productivity, quality, and satisfaction. This meeting and the resulting improvements are critical to the agile principle of self-organization. Look to address these areas during your team sprint retrospectives:

  1.

  Issues that affected your team's general effectiveness, productivity, and quality.

  2.

  Elements that impacted your team's overall satisfaction and project flow.

  3.

  What happened to cause incomplete backlog items

  4.

  What actions will the team take to prevent these issues in the future

• Question 373:

  Your team uses Azure Pipelines to deploy applications.

  You need to ensure that when a failure occurs during the build or release process, all the team members are notified by using Microsoft Teams. The solution must minimize development effort.

  What should you do?

  A. Install the Azure Boards app for Teams and configure a subscription to receive notifications in a channel.

  B. Use Azure Automation to connect to the Azure DevOps REST API and notify the team members.

  C. Use an Azure function to connect to the Azure DevOps REST API and notify the team members.

  D. Install the Azure Pipelines app for Teams and configure a subscription to receive notifications in a channel.

  Correct Answer: D

• Question 374:

  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 375:

  You have a brand policy in a project in Azure DevOps. The policy requires that code always builds successfully.

  You need to ensure that a specific user can always merge change to the master branch, even if the code fails to compile. The solution must use the principle of least privilege.

  What should you do?

  A. From the Security setting of the repository, modify the access control tor the user.

  B. From the Security settings of the branch, modify the access control for the user.

  C. Add the user to the Build Administrators group,

  D. Add the user to the Project Administrators group

  Correct Answer: B

  In some cases, you need to bypass policy requirements so you can push changes to the branch directly or complete a pull request even if branch policies are not satisfied. For these situations, grant the desired permission from the previous list to a user or group. You can scope this permission to an entire project, a repo, or a single branch. Manage this permission along the with other Git permissions.

  You need to restart ACI1 when App1 stops responding.

  What should you do?

  A. Add a liveness probe to the YAML configuration of App1.

  B. Add a readiness probe to the YAML configuration of App1.

  C. Use Connection Monitor in Azure Network Watcher.

• Question 377:

  You configure an Azure Application Insights availability test.

  You need to notify the customer services department at your company by email when availability is degraded.

• Question 379:

  You have a Microsoft ASP.NET Core web app in Azure that is accessed worldwide.

  You need to run a URL ping test once every five minutes and create an alert when the web app is unavailable from specific Azure regions. The solution must minimize development time. What should you do?

  A. Create an Azure Monitor Availability metric and alert.

  B. Create an Azure Application Insights availability test and alert.

  C. Write an Azure function and deploy the function to the specific regions.

  D. Create an Azure Service Health alert for the specific regions.

  Correct Answer: B

  There are three types of Application Insights availability tests:

  1.

  URL ping test: a simple test that you can create in the Azure portal.

  2.

  Multi-step web test

  3.

  Custom Track Availability Tests

  Note: After you've deployed your web app/website, you can set up recurring tests to monitor availability and responsiveness. Azure Application Insights sends web requests to your application at regular intervals from points around the world. It can alert you if your application isn't responding, or if it responds too slowly.

  You can set up availability tests for any HTTP or HTTPS endpoint that is accessible from the public internet. You don't have to make any changes to the website you're testing. In fact, it doesn't even have to be a site you own. You can test the availability of a REST API that your service depends on.

• Question 380:

  Your company develops an application named App1 that is deployed in production.

  As part of an application update, a new service is being added to App1. The new service requires access to an application named App2 that is currently in development.

  You need to ensure that you can deploy the update to App1 before App2 becomes available. You must be able to enable the service in App1 once App2 is deployed.

  What should you do?

  A. Implement a feature flag.

  B. Create a fork in the build.

  C. Create a branch in the build.

  D. Implement a branch policy.

  Correct Answer: A

  Feature flags support a customer-first DevOps mindset, to enable (expose) and disable (hide) features in a solution, even before they are complete and ready for release. Incorrect Answers:

  C: Branch policies are an important part of the Git workflow and enable you to:

  1.

  Isolate work in progress from the completed work in your master branch

  2.

  Guarantee changes build before they get to master
