• Question 303:

  You need to investigate the http server log output to resolve the issue with the ContentUploadService.

  Which command should you use first?

  A. az webapp log
  B. az ams live-output
  C. az monitor activity-log
  D. az container attach
  C. az monitor activity-log

  ---

  Explanation

  Scenario: Users of the ContentUploadService report that they occasionally see HTTP 502 responses on specific pages.

  "502 bad gateway" and "503 service unavailable" are common errors in your app hosted in Azure App Service.

  Microsoft Azure publicizes each time there is a service interruption or performance degradation.

  The az monitor activity-log command manages activity logs.

  Note: Troubleshooting can be divided into three distinct tasks, in sequential order:

  1. Observe and monitor application behavior

  2. Collect data

  3. Mitigate the issue Reference:

• Question 305:

  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 ensure that the subscription client processes all messages.

  Which code segment should you use?

  A. await subscriptionClient.AddRuleAsync(new RuleDescription(RuleDescription.DefaultRuleName, new TrueFilter()));
  B. subscriptionClient = new SubscriptionClient(ServiceBusConnectionString, TopicName, SubscriptionName);
  C. await subscriptionClient.CloseAsync();
  D. subscriptionClient.RegisterMessageHandler(ProcessMessageAsync, messageHandlerOptions);
  D. subscriptionClient.RegisterMessageHandler(ProcessMessageAsync, messageHandlerOptions);

  ---

  Explanation

  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);

• Question 306:

  DRAG DROP

  You are developing an application to retrieve user profile information. The application will use the Microsoft Graph SDK.

  The app must retrieve user profile information by using a Microsoft Graph API call.

  You need to call the Microsoft Graph API from the application.

  In which order should you perform the actions? To answer, move all actions from the list of actions to the answer area and arrange them in the correct order.

  Select and Place:

  Step 1: Register the application with the Microsoft identity platform.

  To authenticate with the Microsoft identity platform endpoint, you must first register your app at the Azure app registration portal

  Step 2: Build a client by using the client app ID

  Step 3: Create an authentication provider

  Create an authentication provider by passing in a client application and graph scopes.

  Code example:

  DeviceCodeProvider authProvider = new DeviceCodeProvider(publicClientApplication, graphScopes);

  // Create a new instance of GraphServiceClient with the authentication provider.

  GraphServiceClient graphClient = new GraphServiceClient(authProvider); Step 4: Create a new instance of the GraphServiceClient

  Step 5: Invoke the request to the Microsoft Graph API

• Question 307:

  You develop and deploy an ASP.NET web app to Azure App Service. You use Application Insights telemetry to monitor the app.

  You must test the app to ensure that the app is available and responsive from various points around the world and at regular intervals. If the app is not responding, you must send an alert to support staff.

  You need to configure a test for the web app.

  Which two test types can you use? Each correct answer presents a complete solution.

  NOTE: Each correct selection is worth one point.

  A. integration
  B. multi-step web
  C. URL ping
  D. unit
  E. load
  B. multi-step web
  C. URL ping

  ---

  Explanation

  There are three types of availability tests:

  1. URL ping test: a simple test that you can create in the Azure portal.

  2. Multi-step web test: A recording of a sequence of web requests, which can be played back to test more complex scenarios. Multi-step web tests are created in Visual Studio Enterprise and uploaded to the portal for execution.

  3. Custom Track Availability Tests: If you decide to create a custom application to run availability tests, the TrackAvailability() method can be used to send the results to Application Insights.

• Question 308:

  HOTSPOT

  You need to implement event routing for retail store location data.

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

  NOTE: Each correct selection is worth one point.

  

  

  ---

  Box 1: Azure Blob Storage

  Azure event publishers and event handlers are at the core of the Event Grid routing-service. Event Grid listens to Azure event publishers, such as Blog Storage, then reacts by routing specific events to Azure event handlers, such as WebHooks. You can easily control this entire process at a granular level through event subscriptions and event filters.

  Box 2: Azure Event Grid

  Azure Event Grid is a highly scalable event-routing service that listens for specific system events, then reacts to them according to your precise specifications. In the past, event handling has relied largely on polling - a high latency, low- efficiency approach that can prove prohibitively expensive at scale.

  Box 3: Azure Logic App

  Event Grid's supported event handlers currently include Event Hubs, WebHooks, Logic Apps, Azure Functions, Azure Automation and Microsoft Flow.

• Question 309:

  You are developing several microservices to run on Azure Container Apps. External HTTP ingress traffic has been enabled for the microservices.

  The microservices must be deployed to the same virtual network and write logs to the same Log Analytics workspace.

  You need to deploy the microservices.

  What should you do?

  A. Enable single revision mode.
  B. Use a separate environment for each container.
  C. Use a private container registry image and single image for all containers.
  D. Use a single environment for all containers.
  E. Enable multiple revision mode.
  A. Enable single revision mode.

• Question 310:

  DRAG DROP

  A company backs up all manufacturing data to Azure Blob Storage. Admins move blobs from hot storage to archive tier storage every month.

  You must automatically move blobs to Archive tier after they have not been modified within 180 days. The path for any item that is not archived must be placed in an existing queue. This operation must be performed automatically once a month. You set the value of TierAgeInDays to 180.

  How should you configure the Logic App? To answer, drag the appropriate triggers or action blocks to the correct trigger or action slots. Each trigger or action block 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: Reoccurance..

  To regularly run tasks, processes, or jobs on specific schedule, you can start your logic app workflow with the built-in Recurrence - Schedule trigger. You can set a date and time as well as a time zone for starting the workflow and a recurrence for repeating that workflow.

  Set the interval and frequency for the recurrence. In this example, set these properties to run your workflow every week.

  

  Box 2: Condition..

  To run specific actions in your logic app only after passing a specified condition, add a conditional statement. This control structure compares the data in your workflow against specific values or fields. You can then specify different actions that run based on whether or not the data meets the condition.

  Box 3: Put a message on a queue

  The path for any item that is not archived must be placed in an existing queue.

  Note: Under If true and If false, add the steps to perform based on whether the condition is met.

  Box 4: ..tier it to Cool or Archive tier.

  Archive item.

  Box 5: List blobs 2
