You are monitoring the health and performance of an Azure web app by using Azure Application Insights.

You need to ensure that an alert is sent when the web app has a sudden rise in performance issues and failures. What should you use?

  1. custom events
  2. Application Insights Profiler
  3. usage analysis
  4. Smart Detection
  5. Continuous export

Answer(s): D

Explanation:

Smart Detection automatically warns you of potential performance problems and failure anomalies in your web application. It performs proactive analysis of the telemetry that your app sends to Application Insights. If there is a sudden rise in failure rates, or abnormal patterns in client or server performance, you get an alert.

HOTSPOT (Drag and Drop is not supported)
You have a project in Azure DevOps named Contoso App that contains pipelines in Azure Pipelines for GitHub repositories. You need to ensure that developers receive Microsoft Teams notifications when there are failures in a pipeline of Contoso App. What should you run in Teams? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:




Box 1: subscribe
To start monitoring all pipelines in a project, use the following command inside a channel: @azure pipelines subscribe [project url]
Box 2: https://dev.azure.com/contoso/contoso-app/
Subscribe to a pipeline or all pipelines in a project to receive notifications: @azure pipelines subscribe [pipeline url/ project url]



You have a private GitHub repository.
You need to display the commit status of the repository on Azure Boards.

What should you do first?

  1. Configure multi-factor authentication (MFA) for your GitHub account.
  2. Add the Azure Pipelines app to the GitHub repository.
  3. Add the Azure Boards app to the repository.
  4. Create a GitHub action in GitHub.

Answer(s): C

Explanation:

To connect Azure Boards to GitHub.com, connect and configure from Azure Boards. Or, alternatively, install and configure the Azure Boards app from GitHub. Both methods have been streamlined and support authenticating and operating via the app rather than an individual.

Note (see step 4 below):
Add a GitHub connection:
Sign into Azure Boards.
Choose (1) Project Settings, choose (2) GitHub connections and then (3) Connect your GitHub account.
If this is your first time connecting to GitHub from Azure Boards, you will be asked to sign in using your GitHub credentials. Choose an account for which you are an administrator for the repositories you want to connect to.
The Add GitHub Repositories dialog automatically displays and selects all GitHub.com repositories for which you are an administrator. Unselect any repositories that you don't want to participate in the integration.
