  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 are developing an Azure Service application that processes queue data when it receives a message from a mobile application. Messages may not be sent to the service consistently.

  You have the following requirements:

  1. Queue size must not grow larger than 80 gigabytes (GB).

  2. Use first-in-first-out (FIFO) ordering of messages.

  3. Minimize Azure costs.

  You need to implement the messaging solution.

  Solution: Use the .Net API to add a message to an Azure Service Bus Queue from the mobile application. Create an Azure Windows VM that is triggered from Azure Service Bus Queue.

  Does the solution meet the goal?

  A. Yes
  B. No
  B. No

  Explanation

  Don't use a VM, instead create an Azure Function App that uses an Azure Service Bus Queue trigger.

• Question 543:

  You deploy an Azure Container Apps app and disable ingress on the container app.

  Users report that they are unable to access the container app. You investigate and observe that the app has scaled to 0 instances.

  You need to resolve the issue with the container app.

  Solution: Enable ingress, create an HTTP scale rule, and apply the rule to the container app.

  Does the solution meet the goal?

  A. Yes
  B. No
  A. Yes

  ---

  Explanation

  Scale a container app

  Azure Container Apps manages automatic horizontal scaling through a set of declarative scaling rules. As a container app scales out, new instances of the container app are created on-demand. These instances are known as replicas.

  Add scale rule

  Add an HTTP scale rule to your container app by running the az containerapp update command.

  az containerapp update \

  --name my-container-app \

  --resource-group my-container-apps \

  --scale-rule-name my-http-scale-rule \

  --scale-rule-http-concurrency 1

  This command adds an HTTP scale rule to your container app with the name my-http-scale-rule and a concurrency setting of 1. If your app receives more than one concurrent HTTP request, the runtime creates replicas of your app to handle the requests.

  The update command returns the new configuration as a JSON response to verify your request was a success.

• Question 544:

  HOTSPOT

  You are developing a service where customers can report news events from a browser using Azure Web PubSub. The service is implemented as an Azure Function App that uses the JSON WebSocket subprotocol to receive news events.

  You need to implement the bindings for the Azure Function App.

  How should you configure the binding? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  

  

  ---

  Box 1: webPubSubTrigger

  WebPubSubTrigger is used when you need to handle requests from service side.

  Example:

  "bindings": [

  {

  "type": "webPubSubTrigger",

  "direction": "in",

  "name": "data",

  "hub": "simplechat",

  "eventName": "message",

  "eventType": "user"

  }, Box 2: user

  eventType - Required - the value must be set as the event type of messages for the function to be triggered. The value should be either user or system.

• Question 545:

  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 on the review screen.

  You are developing an application that needs to react to events from multiple Azure services, such as Azure Blob Storage and Azure Resource Manager, in near real time.

  The application must meet the following requirements:

  1. Handle a high volume of events without manual intervention.

  2. Receive only specific events relevant to your application, based on event types or resource patterns.

  3. Ensure that no events are missed, even if the processing application is temporarily unavailable.

  4. Use Azure Functions for processing events without managing any infrastructure.

  5. Minimize the amount of custom code required for event routing and handling.

  You need to develop the solution.

  Solution: Set up Azure Event Hubs to receive events from the Azure services. Develop a custom application using Azure Functions with Event Hub triggers to process the events. Implement custom filtering logic within the functions to select relevant events.

  Does the solution meet the goal?

  A. Yes
  B. No
  B. No

• Question 546:

  DRAG DROP

  You develop software solutions for a mobile delivery service. You are developing a mobile app that users can use to order from a restaurant in their area; The app uses the following workflow:

  1. A driver selects the restaurants for which they will deliver orders.

  2. Orders are sent to all available drivers in an area;

  3. Only orders for the selected restaurants will appear for the driver.

  4. The first driver to accept an order removes it from the list of available orders.

  You need to implement an Azure Service Bus solution.

  Which three 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:

  Box 1: Create a single Service Bus Namespace

  To begin using Service Bus messaging entities in Azure, you must first create a namespace with a name that is unique across Azure. A namespace provides a scoping container for addressing Service Bus resources within your application.

  Box 2: Create a Service Bus Topic for each restaurant for which a driver can receive messages.

  Create topics.

  Box 3: Create a Service Bus subscription for each restaurant for which a driver can receive orders.

  Topics can have multiple, independent subscriptions.

  Explanation

  Methods to Get User Identity and Claims in a .NET Azure Functions App include: ClaimsPrincipal from the Request Context

  The ClaimsPrincipal object is also available as part of the request context and can be extracted from the HttpRequest.HttpContext.

  User Claims from the Request Headers.

  App Service passes user claims to the app by using special request headers.

  If your user is signed in properly the claims should be in the header of all requests which should allow you to retrieve the claims using claims principal, i shouldnt need to write extra code to hit an api for all that information

• Question 548:

  HOTSPOT

  You are developing an app that manages users for a video game. You plan to store the region, email address, and phone number for the player. Some players may not have a phone number. The player's region will be used to load-balance data.

  Data for the app must be stored in Azure Table Storage.

  You need to develop code to retrieve data for an individual player.

  How should you complete the code? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  

  

  ---

  Box 1: region

  The player's region will be used to load-balance data.

  Choosing the PartitionKey.

  The core of any table's design is based on its scalability, the queries used to access it, and storage operation requirements. The PartitionKey values you choose will dictate how a table will be partitioned and the type of queries that can be used. Storage operations, in particular inserts, can also affect your choice of PartitionKey values.

  Box 2: email

  Not phone number some players may not have a phone number.

  Box 3: CloudTable

  Box 4 : TableOperation query =..

  Box 5: TableResult

• Question 549:

  You develop Azure solutions.

  You must connect to a No-SQL globally-distributed database by using the .NET API.

  You need to create an object to configure and execute requests in the database.

  Which code segment should you use?

  A. database_name = 'MyDatabase' database = client.create_database_if_not_exists(id=database_name)
  B. client = CosmosClient(endpoint, key)
  C. container_name = 'MyContainer' container = database.create_container_if_not_exists( id=container_name, partition_key=PartitionKey(path="/lastName"), offer_throughput=400 )
  B. client = CosmosClient(endpoint, key)

  ---

  Explanation

  CosmosClient has to be created before you can do option A and C to create databases and execute requests.client = CosmosClient(endpoint, key)database_name = 'MyDatabase'database = client.create_database_if_not_exists (id=database_name)container_name = 'MyContainer'container = database.create_container_if_not_exists(id=container_name, partition_key=PartitionKey(path="/lastName"), offer_throughput=400 )
