• Question 395:

  You have an Azure DevOps project named Project1 and an Azure subscription named Sub1.

  You need to prevent releases from being deployed unless the releases comply with the Azure Policy rules assigned to Sub1.

  What should you do in the release pipeline of Project1?

  A. Create a pipeline variable.

  B. Add a deployment gate.

  C. Configure a deployment trigger.

  D. Modify the Deployment queue settings.

  Correct Answer: B

  You can check policy compliance with gates.

  You can extend the approval process for the release by adding a gate. Gates allow you to configure automated calls to external services, where the results are used to approve or reject a deployment.

  You can use gates to ensure that the release meets a wide range or criteria, without requiring user intervention.

• Question 396:

  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 Appl 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:

  1.

  Identify whether individual instances of VMSSl are eligible for an upgrade operation.

  2.

  Minimize administrative effort.

  What should you include in the recommendation?

  A. the Custom Script Extension

  B. the Application Health extension

  C. Azure Monitor autoscale

  D. an Azure Load Balancer health probe

  Correct Answer: B

• Question 397:

  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?

  A. Application Insights Profiler

  B. Continuous export

  C. Smart Detection

  D. custom events

  E. usage analysis

  Correct Answer: C

  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.

• Question 398:

  You have a private GitHub repository.

  You need to display the commit status of the repository on Azure Boards.

  What should you do first?

  A. Create a GitHub action in GitHub.

  B. Add the Azure Pipelines app to the GitHub repository.

  C. Configure multi-factor authentication (MFA) for your GitHub account.

  D. Add the Azure Boards app to the repository.

  Correct Answer: D

  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.

• Question 399:

  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.

  A. an Azure Monitor alert that has a dynamic threshold

  B. an Azure Automation runbook

  C. an Azure Monitor alert that uses an action group that has an email action

  D. the Azure Monitor autoscale settings

  E. an Azure Monitor alert that has a static threshold

  Correct Answer: AB

  You can use Azure Monitor to monitor base-level metrics and logs for most services in Azure. You can call Azure Automation runbooks by using action groups or by using classic alerts to automate tasks

  based on alerts.

  Metric Alert with Dynamic Thresholds detection leverages advanced machine learning (ML) to learn metrics' historical behavior, identify patterns and anomalies that indicate possible service issues. It provides support of both a simple UI and

  operations at scale by allowing users to configure alert rules through the Azure Resource Manager API, in a fully automated manner.

• Question 400:

  You use Azure Pipelines to manage project builds and deployments.

  You plan to use Azure Pipelines for Microsoft Teams to notify the legal team when a new build is ready for release.

  You need to configure the Organization Settings in Azure DevOps to support Azure Pipelines for Microsoft Teams.

  What should you turn on?

  A. Azure Active Directory Conditional Access Policy Validation

  B. Alternate authentication credentials

  C. Third-party application access via OAuth

  D. SSH authentication

  Correct Answer: C

  The Azure Pipelines app uses the OAuth authentication protocol, and requires Third-party application access via OAuth for the organization to be enabled. To enable this setting, navigate to Organization Settings > Security > Policies, and set the Third-party application access via OAuth for the organization setting to On.
