Microsoft Microsoft Certifications AZ-204 Questions & Answers

• Question 431:

  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, add a Job to a Batch account.

  B. In a .NET method, call the method: BatchClient.PoolOperations.CreateJob

  C. In Python, implement the class: JobAddParameter

  D. In Azure CLI, run the command: az batch pool create

  E. In a .NET method, call the method: BatchClient.PoolOperations.CreatePool

  F. In Python, implement the class: TaskAddParameter

  G. In the Azure CLI, run the command: az batch account create

  Correct Answer: B

  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.

  Note:

  Step 1: Create a pool of compute nodes. When you create a pool, you specify the number of compute nodes for the pool, their size, and the operating system. When each task in your job runs, it's assigned to execute on one of the nodes in

  your pool.

  Step 2: Create a job. A job manages a collection of tasks. You associate each job to a specific pool where that job's tasks will run.

  Step 3: Add tasks to the job. Each task runs the application or script that you uploaded to process the data files it downloads from your Storage account. As each task completes, it can upload its output to Azure Storage.

  Incorrect Answers:

  C, F: 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.

  E: BatchClient.PoolOperations does not have a CreateJob method.

  You are developing a website that will run as an Azure Web App. Users will authenticate by using their Azure Active Directory (Azure AD) credentials.

  You plan to assign users one of the following permission levels for the website: admin, normal, and reader. A user's Azure AD group membership must be used to determine the permission level. You need to configure authorization.

  Solution: Configure the Azure Web App for the website to allow only authenticated requests and require Azure AD log on.

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: B

  Instead in the Azure AD application's manifest, set value of the groupMembershipClaims option to All. References: https://blogs.msdn.microsoft.com/waws/2017/03/13/azure-app-service-authentication-aad-groups/

• Question 433:

  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

  You are developing a website that will run as an Azure Web App. Users will authenticate by using their Azure Active Directory (Azure AD) credentials.

  You plan to assign users one of the following permission levels for the website: admin, normal, and reader. A user's Azure AD group membership must be used to determine the permission level. You need to configure authorization.

  Solution:

  1.

  Create a new Azure AD application's manifest, set value of the groupMembershipClaims option to All.

  2.

  In the website, use the value of the groups claim from the JWI for the user to determine permissions. Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: A

  To configure Manifest to include Group Claims in Auth Token

  1.

  Go to Azure Active Directory to configure the Manifest. Click on Azure Active Directory, and go to App registrations to find your application

  2.

  Click on your application (or search for it if you have a lot of apps) and edit the Manifest by clicking on it.

  3.

  Locate the "groupMembershipClaims" setting. Set its value to either "SecurityGroup" or "All". To help you decide which:

  "SecurityGroup" - groups claim will contain the identifiers of all security groups of which the user is a member.

  "All" - groups claim will contain the identifiers of all security groups and all distribution lists of which the user is a member

  Now your application will include group claims in your manifest and you can use this fact in your code.

• Question 437:

  A company is implementing a publish-subscribe (Pub/Sub) messaging component by using Azure Service Bus. You are developing the first subscription application.

  In the Azure portal you see that messages are being sent to the subscription for each topic. You create and initialize a subscription client object by supplying the correct details, but the subscription application is still not consuming the

  messages.

  You need to complete the source code of the subscription client

  What should you do?

  A. await subscriptionClient.CloseAsync();

  B. await subscriptionClient.AddRuleAsync(new RuleDescription(RuleDescription.DefaultRuleName, new TrueFilter()));

  C. subscriptionClient.RegisterMessageHandler(ProcessMessagesAsync, messageHandlerOptions);

  D. subscriptionClient = new SubscriptionClient(ServiceBusConnectionString, TopicName, SubscriptionName);

  Correct Answer: C

  Using topic client, call RegisterMessageHandler which is used to receive messages continuously from the entity. It registers a message handler and begins a new thread to receive messages. This handler is waited on every time a new message is received by the receiver.

  subscriptionClient.RegisterMessageHandler(ReceiveMessagesAsync, messageHandlerOptions);

  Margie's Travel is an international travel and bookings management service. The company is expanding into restaurant bookings. You are tasked with implementing Azure Search for the restaurants listed in their solution.

  You create the index in Azure Search.

  You need to import the restaurant data into the Azure Search service by using the Azure Search .NET SDK.

  Solution:

  1.

  Create a SearchIndexClient object to connect to the search index

  2.

  Create an IndexBatch that contains the documents which must be added.

  3.

  Call the Documents.Index method of the SearchIndexClient and pass the IndexBatch.

  Does the solution meet the goal?

  A. Yes

  B. No

  Correct Answer: A

  1.

  The index needs to be populated. To do this, we will need a SearchIndexClient. There are two ways to obtain one: by constructing it, or by calling Indexes.GetClient on the SearchServiceClient. Here we will use the first method.

  2.

  Create the indexBatch with the documents

  Something like:

  var hotels = new Hotel[];

  {

  new Hotel()

  {

  HotelId = "3",

  BaseRate = 129.99,

  Description = "Close to town hall and the river"

  }

  };

  ...

  var batch = IndexBatch.Upload(hotels);

  3.

  The next step is to populate the newly-created index

  Example:

  var batch = IndexBatch.Upload(hotels);

  try { indexClient.Documents.Index(batch); }

• Question 440:

  You are developing a project management service by using ASP.NET. The service hosts conservations, files, to-do lists, and a calendar that users can interact with at any time.

  The application uses Azure Search for allowing users to search for keywords in the project data.

  You need to implement code that creates the object which is used to create indexes in the Azure Search service.

  Which two objects should you use? Each correct answer presents part of the solution.

  NOTE: Each correct selection is worth one point.

  A. SearchCredentials

  B. SearchIndexClient

  C. SearchServiceClient

  D. SearchService

  Correct Answer: BC

  The various client libraries define classes like Index, Field, and Document, as well as operations like Indexes.Create and Documents.Search on the SearchServiceClient and SearchIndexClient classes.

  Example:

  The sample application we'll be exploring creates a new index named "hotels", populates it with a few documents, then executes some search queries. Here is the main program, showing the overall flow:

  / This sample shows how to delete, create, upload documents and query an index

  static void Main(string[] args)

  {

  IConfigurationBuilder builder = new ConfigurationBuilder().AddJsonFile("appsettings.json");

  IConfigurationRoot configuration = builder.Build();

  SearchServiceClient serviceClient = CreateSearchServiceClient(configuration);

  Console.WriteLine("{0}", "Deleting index...\n");

  DeleteHotelsIndexIfExists(serviceClient);

  Console.WriteLine("{0}", "Creating index...\n");

  CreateHotelsIndex(serviceClient);

  ISearchIndexClient indexClient = serviceClient.Indexes.GetClient("hotels");
