Note: This question is part of a series of questions that present the samescenario. 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 DevOps project.
Your build process creates several artifacts.
You need to deploy the artifacts to on-premises servers.
Solution:You deploy a Kubernetes cluster on-premises. You deploy a Helm agent to the cluster. You add a Download Build Artifacts task to the deployment pipeline.
Does this meet the goal?
Instead you should deploy an Azureself-hosted agent to an on-premises server.
Note: To build your code or deploy your software using Azure Pipelines, you need at least one agent.
If your on-premises environments do not have connectivity to a Microsoft-hosted agent pool (which is typically the case due to intermediate firewalls), you'll need to manually configure a self-hosted agent on on-premises computer(s).
Note 2: As we [Microsoft] are launching this new experience in preview, we are currently optimizing it for Azure Kubernetes Service (AKS) and Azure Container Registry (ACR). Other Kubernetes clusters, for example running on-premises or in other clouds, as well as other container registries, can be used, but require setting up a Service Account and connection manually.

You manage projects by using Azure Boards.
You have a current work item name item A that is dependent on a work item named item3.
You need to define the dependency for item A.
What should you do in the web portal for Azure DevOps?
You are automating the build process for a Java-based application by using Azure DevOps.
You need to add code coverage testing and publish the outcomes to the pipeline.
What should you use?
Use Publish Code CoverageResults task in a build pipeline to publish code coverage results to Azure Pipelines or TFS, which were produced by a build in Cobertura or JaCoCo format.
https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/test/publish-code-coverage-results
Your company uses Azure DevOps for the build pipelines and deployment pipelines of Java-based projects.
You need to recommend a strategy for managing technical debt.
Which action should you include in the recommendation?
You can manage technical debt with Sonar Rube and Azure DevOps.
Note: Technical debt is the set of problems in a development effort that make forward progress on customer value inefficient. Technical debt saps productivity by making code hard to understand, fragile, time-consuming to change, difficult to validate, and creates unplanned work that blocks progress. Unless they are managed, technical debt can accumulate and hurt the overall qualityof the software and the productivity of the development team in the long term
SonarQube an open source platform for continuous inspection of code quality to perform automatic reviews with static analysis of code to:
Detect Bugs
Code Smells
Security Vulnerabilities
Centralize Quality

SIMULATION
You have several apps that use an Azure SQLDatabase named db1.
You need to ensure that queries to db1 are tuned by Azure over time. The solution must only apply to db1.
To complete this task, sign in to the Microsoft Azure portal.
1. To enable automatictuning on a single database, navigate to the database in the Azure portal and select Automatic tuning.
2. Select the automatic tuning options you want to enable and select Apply.
Note: Individual automatic tuning settings can be separately configuredfor each database. You can manually configure an individual automatic tuning option, or specify that an option inherits its settings from the server.
