You have an existing build pipeline in Azure Pipelines.
You need to use incremental builds without purging the environment between pipeline executions.
What should you use?
정답: Explanation:
When you run a pipeline on a self-hosted agent, by default, none of the subdirectories are cleaned in between two consecutive runs. As a result, you can do incremental builds and deployments, provided that tasks are implemented to make use of that. You can override this behavior using the workspace setting on the job.

Question No : 3
Your company is building a new solution in Java.
The company currently uses a SonarQube server to analyze the code of .NET solutions.
You need to analyze and monitor the code quality of the Java solution.
Which task types should you add to the build pipeline?
정답: Explanation:
SonarQube is a set of static analyzers that can be used to identify areas of improvement in
your code. It allows you to analyze the technical debt in your project and keep track of it in the future. With Maven and Gradle build tasks, you can run SonarQube analysis with minimal setup in a new or existing Azure DevOps Services build task.

Question No : 8
DRAG DROP
You are configuring the settings of a new Git repository in Azure Repos.
You need to ensure that pull requests in a branch meet the following criteria before they are merged:
✑ Committed code must compile successfully.
✑ Pull requests must have a Quality Gate status of Passed in SonarCloud.
Which policy type should you configure for each requirement? To answer, drag the appropriate policy types to the correct requirements. Each policy type 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.
정답:
Explanation:
Box 1: A check-in policy
Administrators of Team Foundation version control can add check-in policy requirements. These check-in policies require the user to take actions when they conduct a check-in to source control.
By default, the following check-in policy types are available:
✑ Builds Requires that the last build was successful before a check-in.
✑ Code Analysis Requires that code analysis is run before check-in.
✑ Work Items Requires that one or more work items be associated with the check-in.
Box 2: Build policy

You have a policy stating that approvals must occur within eight hours.
You discover that deployments fail if the approvals lake longer than two hours.
You need to ensure that the deployments only fail if the approvals take longer than eight hours.
Solution: From Pre-deployment conditions, you modify the Timeout setting for pre-deployment approvals.
Does this meet the goal?

HOTSPOT
Your company uses Team Foundation Server 2013 (TFS 2013).
You plan to migrate to Azure DevOps.
You need to recommend a migration strategy that meets the following requirements:
✑ Preserves the dates of Team Foundation Version Control changesets
✑ Preserves the changes dates of work items revisions
✑ Minimizes migration effort
✑ Migrates all TFS artifacts
What should you recommend? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
정답:
Explanation:
Box 1: Upgrade TFS to the most recent RTM release.
One of the major prerequisites for migrating your Team Foundation Server database is to get your database schema version as close as possible to what is currently deployed in Azure Devops Services.
Box 2: Use the TFS Database Import Service
In Phase 3 of your migration project, you will work on upgrading your Team Foundation Server to one of the supported versions for the Database Import Service in Azure Devops Services.

Question No : 12
HOTSPOT
You use Azure DevOps to manage the build and deployment of an app named App1.
You have a release pipeline that deploys a virtual machine named VM1.
You plan to monitor the release pipeline by using Azure Monitor
You need to create an alert to monitor the performance of VM1. The alert must be triggered when the average CPU usage exceeds 70 percent for five minutes. The alert must calculate the average once every minute.
How should you configure the alert rule? To answer, select the appropriate options in the answer area.
정답:
Explanation:
Box 1: 5 minutes
The alert must calculate the average once every minute.
Note: We [Microsoft] recommend choosing an Aggregation granularity (Period) that is larger than the Frequency of evaluation, to reduce the likelihood of missing the first evaluation of added time series
Box 2: Static
Box 3: Greater than
Example, say you have an App Service plan for your website. You want to monitor CPU usage on multiple instances running your web site/app.
You can do that using a metric alert rule as follows:
✑ Target resource: myAppServicePlan
✑ Metric: Percentage CPU
✑ Condition Type: Static
✑ Dimensions
✑ Instance = InstanceName1, InstanceName2
✑ Time Aggregation: Average
✑ Period: Over the last 5 mins
✑ Frequency: 1 min
✑ Operator: GreaterThan
✑ Threshold: 70
✑ Like before, this rule monitors if the average CPU usage for the last 5 minutes exceeds 70%.
✑ Aggregation granularity
Question No : 13
You use Azure SQL Database Intelligent Insights and Azure Application Insights for monitoring.
You need to write ad-hoc queries against the monitoring data.
Which query language should you use?
정답: Explanation:
Azure Monitor Logs is based on Azure Data Explorer, and log queries are written using the same Kusto query language (KQL). This is a rich language designed to be easy to read and author, and you should be able to start using it with minimal guidance.
