AZ-400 Practice Test

AZ-400 Practice Test practice questions, page 20 of 23, with answer review and explanations.

Question 96

You have an Azure DevOps organization named Contoso and an Azure subscription. The subscription contains an Azure virtual machine scale set named VMSS1 and an Azure Standard Load Balancer named LB1. LB1 distributes incoming requests across VMSS1 instances. You use Azure DevOps to build a web app named App1 and deploy App1 to VMSS1. App1 is accessible via HTTPS only and configured to require mutual authentication by using a client certificate. You need to recommend a solution for implementing a health check of App1. The solution must meet the following requirements: ✑ Identify whether individual instances of VMSS1 are eligible for an upgrade operation. ✑ Minimize administrative effort. What should you include in the recommendation?

  1. an Azure Load Balancer health probe
  2. Azure Monitor autoscale
  3. the Custom Script Extension
  4. the Application Health extension

Question 97

You have an application named App1 that has a custom domain of app.contoso.com. You create a test in Azure Application Insights as shown in the following exhibit. Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic. NOTE: Each correct selection is worth one point. Hot Area:

Question 98

You have a build pipeline in Azure Pipelines that occasionally fails. You discover that a test measuring the response time of an API endpoint causes the failures. You need to prevent the build pipeline from failing due to the test. Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

  1. Set Flaky test detection to Off.
  2. Clear Flaky tests included in test pass percentage.
  3. Enable Test Impact Analysis (TIA).
  4. Manually mark the test as flaky.
  5. Enable test slicing.

Question 99

Your company hosts a web application in Azure. The company uses Azure Pipelines for the build and release management of the application. Stakeholders report that the past few releases have negatively affected system performance. You configure alerts in Azure Monitor. You need to ensure that new releases are only deployed to production if the releases meet defined performance baseline criteria in the staging environment first. What should you use to prevent the deployment of releases that fall to meet the performance baseline?

  1. an Azure Scheduler job
  2. a trigger
  3. a gate
  4. an Azure function

Question 100

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You manage a project in Azure DevOps. You need to prevent the configuration of the project from changing over time. Solution: Perform a Subscription Health scan when packages are created. Does this meet the goal?

  1. Yes
  2. No
