Update the default home page of the IIS web server.

How should you configure the DSC configuration file? To answer, select the appropriate options in the answer area.

NOTE:Each correct selection is worth one point.

You have an Azure web app named webapp1 that uses the .NET Core runtime slack. You have an Azure Application insights resourcenamed Applnsights1 that collects telemetry data generated by webapp1

You plan to deploy webapp1 by using an Azure DevOps pipeline.

You need to modify the sampling rate of the telemetry data processed by Applnsights1 without having to redeploy webapp1 after each modification.

What should you do? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

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 use Azure Pipelines to build and test a React js application

You have a pipeline that has a single job.

You discover thatinstalling JavaScript packages from npm lakes approximately five minutes each time you run the pipeline.

You need to recommend a solution to reduce the pipeline execution time.

Solution: You recommend enabling pipeline caching.

Does this meet the goal?

Your company wants to use Azure Application Insights to understand how user behaviors affect an application.

Which Application Insights tool should you use to analyze each behavior? To answer, drag the appropriate tools to the correct behaviors. Each tool 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.

You have a GitHub repository named Repo1.

You plan to implement continuous integration and continuous delivery (CI/CD) by using GitHub Actions.

You need to create a workflow.

Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

You use release pipelines in Azure Pipelines to deploy an app. Secrets required by the pipeline are stored as pipeline variables. Logging of commands is enabled for the Azure Pipelines agent.

You need to prevent the valuesof the secrets from being logged.

What should you do?

You plan to deploy a solution that will include multiple microservices.

You need to recommend a deployment strategy for the microservices The solution must meet the following requirements:

• Enable testing and monitoring of changes during a gradual rollout.

• Control the number of users that will receive new code releases.

Which strategy should you recommend?

You manage an Azure web app that supports an e-commerce website.

You need to increase the logging level when the web app exceeds normal usage patterns. The solution must minimize administrative overhead.

Which two resources should you include in the solution? Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one point.

Your company has a project in Azure DevOps for a new webapplication.

The company identifies security as one of the highest priorities.

You need to recommend a solution to minimize the likelihood that infrastructure credentials will be leaked.

What should you recommend?

You plan to create a project in Azure DevOps. Multiple developers will work on the project. The developers will work offline frequentlyand will require access to the full project history while they are offline.

Which version control solution should you use?

You have an Azure DevOps subscription that contains the projects shown in the following table

You build apps for the projects by using Azure Pipelines.

Which two projects meet the criteria for granting free paralleljobs? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

You have a GitHub repository.

You create a new repository inAzure DevOps.

You need to recommend a procedure to clone the repository from GitHub to Azure DevOps.

What should you recommend?

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 have an Azure pipeline that is used to deploy a web app. The pipeline includes a test suite named TestSuite1. TestSuite1 is used to validate the operations of the web app.

TestSuite1 fails intermittently.

You identify that the failures are unrelated to changes in the source code and execution environment.

You need to minimize troubleshooting effort for the TestSuite1 failures.

Solution: You implement the Test Results Trend widget.

Does this meet the goal?

You have several Azure Active Directory (Azure AD) accounts.

You need to ensure that users use multi-factor authentication (MFA) to access Azure apps from untrusted networks.

What should you configure in Azure AD?

You have a project in Azure DevOps named Project1 that contains two environments named environment1 andenvkonment2.

When a new version of Project1 is released, the latest version is deployed to environment2, and the previous version is redeployed to environments

You need to distribute users across the environments. The solution must meet the following requirements:

• New releases must be available to only a subset of the users.

• You must gradually increase the number of users that can access environment2.

What should you use?
