Microsoft Microsoft Certifications AZ-204 Questions & Answers

• Question 291:

  You are developing an application to manage shipping information for cargo ships. The application will use Azure Cosmos D8 for storage.The application must run offline when ships are at sea. The application must be connected to Azure when ships are in port.

  Which Azure Cosmos D8 API should you use for the application?

  A. Core

  B. MongoDe

  C. Cassandra

  D. Gremlin

  Correct Answer: C

• Question 292:

  You are building a web application that uses the Microsoft identity platform for user authentication.

  You are implementing user identification for the web application.

  You need to retrieve a claim to uniquely identify a user.

  Which claim type should you use?

  A. oid

  B. aud

  C. idp

  D. nonce

  Correct Answer: A

  oid -The object identifier for the user in Azure AD. This value is the immutable and non-reusable identifier of the user. Use this value, not email, as a unique identifier for users; email addresses can change. If you use the Azure AD Graph API

  in your app, object ID is that value used to query profile information.

  Incorrect:

  Not A: aud - Who the token was issued for. This will be the application's client ID.

• Question 293:

  You are designing a web application to manage user satisfaction surveys. The number of questions that a survey includes is variable.

  Application users must be able to display results for a survey as quickly as possible. Users must also be able to quickly compute statistical measures including average values across various groupings of answers.

  Which Azure Cosmos 06 API should you use for the application?

  A. Core

  B. Mongo DB

  C. Gremlin

  D. Table API

  Correct Answer: D

• Question 294:

  Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution. Determine whether the solution meets the stated goals.

  You are developing and deploying several ASP.Net web applications to Azure App Service.

  You plan to save session state information and HTML output.

  You must use a storage mechanism with the following requirements:

  1.

  Share session state across all ASP.NET web applications

  2.

  Support controlled, concurrent access to the same session state data for multiple readers and a single writer

  3.

  Save full HTTP responses for concurrent requests

  You need to store the information.

  Proposed Solution: Add the web applications to Docker containers. Deploy the containers. Deploy the containers to Azure Kubernetes Service (AKS).

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: B

  Instead use Azure Cache for Redis.

  Note: Azure Cache for Redis provides a session state provider that you can use to store your session state in-memory with Azure Cache for Redis instead of a SQL Server database. To use the caching session state provider, first configure your cache, and then configure your ASP.NET application for cache using the Azure Cache for Redis Session State NuGet package.

• Question 295:

  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 and deploy an Azure App Service API app to a Windows-hosted deployment slot named Development. You create additional deployment slots named Testing and Production. You enable auto swap on the Production deployment slot.

  You need to ensure that scripts run and resources are available before a swap operation occurs.

  Solution: Update the app with a method named statuscheck to run the scripts. Update the app settings for the app. Set the WEBSITE_SWAP_WARMUP_PING_PATH and WEBSITE_SWAP_WARMUP_PING_STATUSES with a path to the

  new method and appropriate response codes.

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: B

  These are valid warm-up behavior options, but are not helpful in fixing swap problems.

  Instead update the web.config file to include the applicationInitialization configuration element. Specify custom initialization actions to run the scripts.

  Note: Some apps might require custom warm-up actions before the swap. The applicationInitialization configuration element in web.config lets you specify custom initialization actions. The swap operation waits for this custom warm-up to

  finish before swapping with the target slot. Here's a sample web.config fragment.

• Question 296:

  Your company has several containers based on the following operating systems:

  1.

  Windows Server 2019 Nano Server

  2.

  Windows Server 2019 Server Core

  3.

  Windows Server 2022 Nano Server

  4.

  Windows Server 2022 Server Core

  5.

  Linux

  You plan to migrate the containers to an Azure Kubernetes cluster. What is the minimum number of node pools that the cluster must have?

  A. 1

  B. 2

  C. 3

  D. 6

  Correct Answer: C

• Question 297:

  You develop and deploy an Azure App Service web app to a production environment. You enable the Always On setting and the Application Insights site extensions.

  You deploy a code update and receive multiple failed requests and exceptions in the web app.

  You need to validate the performance and failure counts of the web app in near real time.

  Which Application Insights tool should you use?

  A. Snapshot Debugger

  B. Profiler

  C. Smart Detection

  D. Live Metrics Stream

  E. Application Map

  Correct Answer: D

  Live Metrics Stream Deploying the latest build can be an anxious experience. If there are any problems, you want to know about them right away, so that you can back out if necessary. Live Metrics Stream gives you key metrics with a latency of about one second.

  With Live Metrics Stream, you can:

  *

  Validate a fix while it's released, by watching performance and failure counts.

  *

  Etc.

  

  Incorrect:

  *

  Profiler Azure Application Insights Profiler provides performance traces for applications running in production in Azure. Profiler:

  Captures the data automatically at scale without negatively affecting your users.

  Helps you identify the “hot” code path spending the most time handling a particular web request.

  *

  Snapshot debugger When an exception occurs, you can automatically collect a debug snapshot from your live web application. The snapshot shows the state of source code and variables at the moment the exception was thrown. The Snapshot Debugger in Azure Application Insights monitors exception telemetry from your web app. It collects snapshots on your top-throwing exceptions so that you have the information you need to diagnose issues in production.

• Question 298:

  You develop and deploy a Java RESTful API to Azure App Service.

  You open a browser and navigate to the URL for the API. You receive the following error message:

  

  You need to resolve the error. What should you do?

  A. Bind an SSL certificate

  B. Enable authentication

  C. Enable CORS

  D. Map a custom domain

  E. Add a CDN

  Correct Answer: C

  We need to enable Cross-Origin Resource Sharing (CORS).

• Question 299:

  You have an existing Azure storage account that stores large volumes of data across multiple containers.

  You need to copy all data from the existing storage account to a new storage account. The copy process must meet the following requirements:

  1.

  Automate data movement.

  2.

  Minimize user input required to perform the operation. Ensure that the data movement process is recoverable. What should you use?

  A. AzCopy

  B. Azure Storage Explorer

  C. Azure portal

  D. .NET Storage Client Library

  Correct Answer: A

  You can copy blobs, directories, and containers between storage accounts by using the AzCopy v10 command-line utility. The copy operation is synchronous so when the command returns, that indicates that all files have been copied. Reference:

  https://docs.microsoft.com/en-us/azure/storage/common/storage-use-azcopy-blobs-copy

• Question 300:

  You are developing a medical records document management website. The website is used to store scanned copies of patient intake forms. If the stored intake forms are downloaded from storage by a third party, the content of the forms

  must not be compromised.

  You need to store the intake forms according to the requirements.

  Solution: uk.co.certification.simulator.questionpool.PList@1898d9c0

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: B

  Instead use an Azure Key vault and public key encryption. Store the encrypted from in Azure Storage Blob storage.
