  DRAG DROP

  You develop a web app that uses tier D1 app service plan by using the Web Apps feature of Microsoft Azure App Service.

  Spikes in traffic have caused increases in page load times.

  You need to ensure that the web app automatically scales when CPU load is about 85 percent and minimize costs.

  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.

  NOTE: More than one order of answer choices is correct. You will receive credit for any of the correct orders you select.

  Select and Place:

  Step 1: Configure the web app to the Standard App Service Tier

  The Standard tier supports auto-scaling, and we should minimize the cost.

  Step 2: Enable autoscaling on the web app First enable autoscale

  Step 3: Add a scale rule

  Step 4: Add a Scale condition

• Question 482:

  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 develop an HTTP triggered Azure Function app to process Azure Storage blob data. The app is triggered using an output binding on the blob.

  The app continues to time out after four minutes. The app must process the blob data.

  You need to ensure the app does not time out and processes the blob data.

  Solution: Configure the app to use an App Service hosting plan and enable the Always On setting.

  Does the solution meet the goal?

  A. Yes
  B. No
  B. No

  ---

  Explanation

  Instead pass the HTTP trigger payload into an Azure Service Bus queue to be processed by a queue trigger function and return an immediate HTTP success response.

  Note: Large, long-running functions can cause unexpected timeout issues. General best practices include:

  Whenever possible, refactor large functions into smaller function sets that work together and return responses fast. For example, a webhook or HTTP trigger function might require an acknowledgment response within a certain time limit; it's common for webhooks to require an immediate response. You can pass the HTTP trigger payload into a queue to be processed by a queue trigger function. This approach lets you defer the actual work and return an immediate response.

• Question 483:

  HOTSPOT

  You are developing an Azure Static Web app that contains training materials for a tool company. Each tool's training material is contained In a static web page that Is linked from the tool's publicly available description page.

  A user must be authenticated using Azure AD prior to viewing training.

  You need to ensure.

  That the user can view training material pages after authentication.

  How should you complete the configuration file? To answer, select the appropriate options In the answer area.

  NOTE: Each correct selection is worth one point.

  Box 1: responseOverrides

  Response overrides

  The responseOverrides section provides an opportunity to define a custom response when the server would otherwise return an error code

  Box 2: 401

  401 Unauthorized - Request to restricted pages while unauthenticated

  Incorrect:

  400 Bad request - Invalid invitation link

  403 Forbidden

  User is logged in but doesn't have the roles required to view the page.

  User is logged in but the runtime cannot get the user details from their identity claims.

  There are too many users logged in to the site with custom roles, therefore the runtime can't log in the user

  Box 3: add

  Note: add likely a typo for aad

  Example:

  The following example configuration blocks anonymous access and redirects all unauthenticated users to the Azure Active Directory login page.

  JSON

  {

  "routes": [

  {

  "route": "/*",

  "allowedRoles": ["authenticated"]

  }

  ],

  "responseOverrides": {

  "401": {

  "statusCode": 302,

  "redirect": "/.auth/login/aad"

  }

  }

  } Box 4: =.referrer

  Example:

  Provide an auth redirect for any unauthorized response using responseOverrides in staticwebapp.config.json.

  "responseOverrides":{"401":{"statusCode":302,"redirect":"/.auth/login/aad?post_login_redirect_uri=.referrer"}}

  How should you configure the Maxmemory policy?

  A. Decrease the value of maxmemory-reserved.
  B. Increase the value of maxmemory-reserved.
  C. Set the Maxmemory policy to noeviction.
  D. Set the Maxmemory policy to volatile-lru.
  A. Decrease the value of maxmemory-reserved.

• Question 485:

  HOTSPOT

  You are developing several microservices to run on Azure Container Apps.

  You need to monitor and diagnose the microservices.

  Which features should you use? To answer, select the appropriate feature in the answer area.

  NOTE: Each correct selection is worth one point.

  Box 1: Log streaming

  View console logs from a container in near real-time.

  Log streaming: View real-time log streams from your containers.

  Box 2: Container console

  Debug the microservice from inside the container.

  Container console: Access the container console to debug your application.

  Note: Development and test

  During the development and test phase, real-time access to your containers' application logs and console is critical for debugging issues. Container Apps provides:

  Log streaming: View real-time log streams from your containers.

  Container console: Access the container console to debug your application.

• Question 486:

  You create and publish a new Azure App Service web app.

  User authentication and authorization must use Azure Active Directory (Azure AD).

  You need to configure authentication and authorization.

  What should you do first?

  A. Add an identity provider.
  B. Map an existing custom DNS name.
  C. Create and configure a new app setting.
  D. Add a private certificate.
  E. Create and configure a managed identity.
  A. Add an identity provider.

  ---

  Explanation

  Configure your App Service or Azure Functions app to use Azure AD login

  You configure authentication for Azure App Service or Azure Functions so that your app signs in users with the Microsoft identity platform (Azure AD) as the authentication provider.

  The App Service Authentication feature can automatically create an app registration with the Microsoft identity platform. You can also use a registration that you or a directory admin creates separately.

  Option 1: Create a new app registration automatically

  Use this option unless you need to create an app registration separately. It makes enabling authentication simple and requires just a few clicks. You can customize the app registration in Azure AD once it's created.

  Sign in to the Azure portal and navigate to your app.

  Select Authentication in the menu on the left. Click Add identity provider.

  Select Microsoft in the identity provider dropdown. The option to create a new registration is selected by default. You can change the name of the registration or the supported account types.

  Etc.

• Question 488:

  You are developing a software solution for an autonomous transportation system. The solution uses large data sets and Azure Batch processing to simulate navigation sets for entire fleets of vehicles.

  You need to create compute nodes for the solution on Azure Batch.

  What should you do?

  A. In the Azure portal, create a Batch account.
  B. In a .NET method, call the method: BatchClient.PoolOperations.CreatePool
  C. In Python, implement the class: JobAddParameter
  D. In Python, implement the class: TaskAddParameter
  B. In a .NET method, call the method: BatchClient.PoolOperations.CreatePool

  ---

  Explanation

  A Batch job is a logical grouping of one or more tasks. A job includes settings common to the tasks, such as priority and the pool to run tasks on. The app uses the BatchClient.JobOperations.CreateJob method to create a job on your pool.

  Incorrect Answers:

  C, D: To create a Batch pool in Python, the app uses the PoolAddParameter class to set the number of nodes, VM size, and a pool configuration.
