Microsoft AZ-204 Online Questions & Answers

• Question 231:

  You are developing an inventory tracking solution. The solution includes an Azure Function app containing multiple functions triggered by Azure Cosmos DB. You plan to deploy the solution to multiple Azure regions.

  The solution must meet the following requirements:

  Item results from Azure Cosmos DS must return the most recent committed version of an item.

  Items written to Azure Cosmos DB must provide ordering guarantees.

  You need to configure the consistency level for the Azure Cosmos DB deployments.

  Which consistency level should you use?

  A. consistent prefix
  B. eventual
  C. bounded staleness
  D. strong
  E. session
  D. strong

  ---

  Explanation

  Strong consistency

  Strong consistency offers a linearizability guarantee. Linearizability refers to serving requests concurrently. The reads are guaranteed to return the most recent committed version of an item. A client never sees an uncommitted or partial write.

  Users are always guaranteed to read the latest committed write.

  Incorrect:

  * bounded staleness (and the other weaker consistency levels)

  With Bounded Staleness consistency, reads issued against a non-primary region may not necessarily return the most recent version of the data globally, but are guaranteed to return the most recent version of the data in that region, which will be within the maximum staleness boundary globally.

  Note: Azure Cosmos DB offers five well-defined levels. From strongest to weakest, the levels are:

  Strong

  Bounded staleness

  Session

  Consistent prefix

• Question 232:

  DRAG DROP

  You need to add code at line PC32 in Processing.cs to implement the GetCredentials method in the Processing class.

  How should you complete the code? To answer, drag the appropriate code segments to the correct locations. Each code segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

  NOTE: Each correct selection is worth one point.

  Box 1: AzureServiceTokenProvider()

  Box 2: tp.GetAccessTokenAsync("..")

  Acquiring an access token is then quite easy. Example code:

  private async Task<string> GetAccessTokenAsync()

  {

  var tokenProvider = new AzureServiceTokenProvider();

  return await tokenProvider.GetAccessTokenAsync("

  https://storage.azure.com/");

• Question 234:

  HOTSPOT

  You are debugging an application that is running on Azure Kubernetes cluster named cluster1. The cluster uses Azure Monitor for containers to monitor the cluster.

  The application has sticky sessions enabled on the ingress controller.

  Some customers report a large number of errors in the application over the last 24 hours.

  You need to determine on which virtual machines (VMs) the errors are occurring.

  How should you complete the Azure Monitor query? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  Box 1: ago(1d)

  Box 2: distinct containerID

  Box 3: where ContainerID in (ContainerIDs)

  Box 4: summarize Count by Computer

  Summarize: aggregate groups of rows

  Use summarize to identify groups of records, according to one or more columns, and apply aggregations to them. The most common use of summarize is count, which returns the number of results in each group.

• Question 235:

  Note: The question is included in a number of questions that depicts the identical set-up. However, every question has a distinctive result. Establish if the solution satisfies the requirements.

  You are developing a solution for a public facing API.

  The API back end is hosted in an Azure App Service instance. You have implemented a RESTful service for the API back end.

  You must configure back-end authentication for the API Management service instance.

  Solution: You configure Client cert gateway credentials for the Azure resource.

  Does the solution meet the goal?

  A. Yes
  B. No
  A. Yes

  ---

  Explanation

  API Management allows to secure access to the back-end service of an API using client certificates.

• Question 236:

  A company is developing a solution that allows smart refrigerators to send temperature information to a central location. You have an existing Service Bus.

  The solution must receive and store messages until they can be processed. You create an Azure Service Bus instance by providing a name, pricing tier, subscription, resource group, and location.

  You need to complete the configuration.

  Which Azure CLI or PowerShell command should you run?

  Explanation

  A service bus instance has already been created (Step 2 below). Next is step 3, Create a Service Bus queue.

  Note:

  Steps:

  Step 1: # Create a resource group resourceGroupName="myResourceGroup" az group create --name $resourceGroupName --location eastus

  Step 2: # Create a Service Bus messaging namespace with a unique name namespaceName=myNameSpace$RANDOM az servicebus namespace create --resource-group $resourceGroupName --name $namespaceName --location eastus

  Step 3: # Create a Service Bus queue az servicebus queue create --resource-group $resourceGroupName --namespace-name $namespaceName --name BasicQueue

  Step 4: # Get the connection string for the namespace connectionString=$(az servicebus namespace authorization-rule keys list --resource-group $resourceGroupName --namespace-name $namespaceName --name RootManageSharedAccessKey --query primaryConnectionString --output tsv)

• Question 240:

  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 a software as a service (SaaS) offering to manage photographs. Users upload photos to a web service which then stores the photos in Azure Storage Blob storage. The storage account type is General-purpose V2.

  When photos are uploaded, they must be processed to produce and save a mobile-friendly version of the image. The process to produce a mobile-friendly version of the image must start in less than one minute.

  You need to design the process that starts the photo processing.

  Solution: Convert the Azure Storage account to a BlockBlobStorage storage account.

  Does the solution meet the goal?

  A. Yes
  B. No
  B. No

  ---

  Explanation

  Not necessary to convert the account, instead move photo processing to an Azure Function triggered from the blob upload..

  Azure Storage events allow applications to react to events. Common Blob storage event scenarios include image or video processing, search indexing, or any file-oriented workflow.

  Note: Only storage accounts of kind StorageV2 (general purpose v2) and BlobStorage support event integration. Storage (general purpose v1) does not support integration with Event Grid.
