  A. Update line RA13 to use the async keyword and return an HttpRequest object value.
  B. Configure the Function app to use an App Service hosting plan. Enable the Always On setting of the hosting plan.
  C. Update the function to be stateful by using Durable Functions to process the request payload.

  Explanation

  Async operation tracking

  The HTTP response mentioned previously is designed to help implement long-running HTTP async APIs with Durable Functions. This pattern is sometimes referred to as the polling consumer pattern.

  Both the client and server implementations of this pattern are built into the Durable Functions HTTP APIs.

  Function app

  You perform local testing for the RequestUserApproval function. The following error message displays: 'Timeout value of 00:10:00 exceeded by function: RequestUserApproval'

  The same error message displays when you test the function in an Azure development environment when you run the following Kusto query:

• Question 262:

  HOTSPOT

  You have a web service that is used to pay for food deliveries. The web service uses Azure Cosmos DB as the data store.

  You plan to add a new feature that allows users to set a tip amount. The new feature requires that a property named tip on the document in Cosmos DB must be present and contain a numeric value.

  There are many existing websites and mobile apps that use the web service that will not be updated to set the tip property for some time.

  How should you complete the trigger?

  NOTE: Each correct selection is worth one point.

  Box 1: getContext().getRequest();

  Box 2: if(isNaN(i)["tip"] .. In JavaScript, there are two ways to check if a variable is a number :

  isNaN() - Stands for "is Not a Number", if variable is not a number, it return true, else return false. typeof - If variable is a number, it will returns a string named "number".

  Box 3:r.setBody(i);

  // update the item that will be created

• Question 263:

  You have a new Azure subscription. You are developing an internal website for employees to view sensitive data. The website uses Azure Active Directory (Azure AD) for authentication.

  You need to implement multifactor authentication for the website.

  Which two actions should you perform? Each correct answer presents part of the solution.

  NOTE: Each correct selection is worth one point.

  A. Configure the website to use Azure AD B2C.
  B. In Azure AD, create a new conditional access policy.
  C. Upgrade to Azure AD Premium.
  D. In Azure AD, enable application proxy.
  E. In Azure AD conditional access, enable the baseline policy.
  B. In Azure AD, create a new conditional access policy.
  C. Upgrade to Azure AD Premium.

  Explanation

  B: MFA Enabled by conditional access policy. It is the most flexible means to enable two-step verification for your users. Enabling using conditional access policy only works for Azure MFA in the cloud and is a premium feature of Azure AD.

  C: Multi-Factor Authentication comes as part of the following offerings: Azure Active Directory Premium licenses - Full featured use of Azure Multi-Factor Authentication Service (Cloud) or Azure Multi-Factor Authentication Server (On-premises).

• Question 264:

  DRAG DROP

  You develop an application. You plan to host the application on a set of virtual machines (VMs) in Azure.

  You need to configure Azure Monitor to collect logs from the application.

  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.

  Select and Place:

  Step 1: Create a Log Analytics workspace.

  First create the workspace.

  Step 2: Add a VMInsights solution.

  Before a Log Analytics workspace can be used with VM insights, it must have the VMInsights solution installed.

  Step 3: Install agents on the VM and VM scale set to be monitored.

  Prior to onboarding agents, you must create and configure a workspace. Install or update the Application Insights Agent as an extension for Azure virtual machines and VM scalet sets.

  Step 4: Create an Application Insights resource

  Sign in to the Azure portal, and create an Application Insights resource.

  

  Once a workspace-based Application Insights resource has been created, configuring monitoring is relatively straightforward.

• Question 268:

  DRAG DROP

  You are implementing an Azure solution that uses Azure Cosmos DB and the latest Azure Cosmos DB SDK. You add a change feed processor to a new container instance.

  You attempt to read a batch of 100 documents. The process fails when reading one of the documents. The solution must monitor the progress of the change feed processor instance on the new container as the change feed is read. You must prevent the change feed processor from retrying the entire batch when one document cannot be read.

  You need to implement the change feed processor to read the documents.

  Which features should you use? To answer, drag the appropriate features to the cored requirements. Each feature 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 cored selection is worth one point.

  Box 1: Change feed estimator

  You can use the change feed estimator to monitor the progress of your change feed processor instances as they read the change feed or use the life cycle notifications to detect underlying failures.

  Box 2: Dead-letter queue

  To prevent your change feed processor from getting "stuck" continuously retrying the same batch of changes, you should add logic in your delegate code to write documents, upon exception, to a dead-letter queue. This design ensures that you can keep track of unprocessed changes while still being able to continue to process future changes. The dead-letter queue might be another Cosmos container. The exact data store does not matter, simply that the unprocessed changes are persisted.

• Question 269:

  You use Azure Table storage to store customer information for an application. The data contains customer details and is partitioned by last name.

  You need to create a query that returns all customers with the last name Smith.

  Which code segment should you use?

  A. TableQuery.GenerateFilterCondition("PartitionKey", Equals, "Smith")
  B. TableQuery.GenerateFilterCondition("LastName", Equals, "Smith")
  C. TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, "Smith")
  D. TableQuery.GenerateFilterCondition("LastName", QueryComparisons.Equal, "Smith")
  C. TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, "Smith")

  ---

  Explanation

  Retrieve all entities in a partition. The following code example specifies a filter for entities where 'Smith' is the partition key. This example prints the fields of each entity in the query results to the console.

  Construct the query operation for all customer entities where PartitionKey="Smith".

  TableQuery<CustomerEntity> query = new TableQuery<CustomerEntity>().Where(TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, "Smith")); References:

• Question 270:

  HOTSPOT

  You are building a traffic monitoring system that monitors traffic along six highways. The system produces time series analysis-based reports for each highway. Data from traffic sensors are stored in Azure Event Hub.

  Traffic data is consumed by four departments. Each department has an Azure Web App that displays the time series-based reports and contains a WebJob that processes the incoming data from Event Hub. All Web Apps run on App Service Plans with three instances.

  Data throughput must be maximized. Latency must be minimized.

  You need to implement the Azure Event Hub.

  Which settings should you use? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.
