    Answer:

    Explanation: Step 1: Create an intent for each event type Identify your intents
    Step 2: Add example utterances
    Create example utterances for each intent Step 3: Create a List Entity
    Identify your entities
    A list entity is an explicitly specified list of values. Each value consists of one or more synonyms. In a travel app, you might choose to create a list entity to represent airport names.

      NEW QUESTION 5
      You are creating a collaborative image hosting platform as an ASP.NET MVC web application. Users add, update, and modify images on the platform. Images are stored in Azure Blob storage.
      More than one user at a time must be able to modify the same image. You need to implement optimistic concurrency for uploading images.
      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.
      NOTE: Each correct solution is worth one point.
      AZ-202 dumps exhibit

        Answer:

        Explanation: Optimistic concurrency means allowing concurrency conflicts to happen, and then reacting appropriately if they do.
        For the PUT method, If-Match can be used to prevent the lost update problem. It can check if the modification of a resource that the user wants to upload will not override another change that has been done since the original resource was fetched. If the request cannot be fulfilled, the 412 (Precondition Failed) response is returned.

        NEW QUESTION 6
        You develop a microservice solution for a company.
        The solution uses the Actor design pattern for all services including mappings, GPS, and communication. The mapping and communication systems must persist state on disk. The GPS system must persist state
        in-memory. All Actors must have a service replica count of three.
        You need to implement code for the GPS system.
        How should you complete the code segment? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

          Answer:

          Explanation: Example:
          The state manager retrieval methods return a reference to an object in local memory. Modifying this object in local memory alone does not cause it to be saved durably. When an object is retrieved from the state manager and modified, it must be reinserted into the state manager to be saved durably.
          [StatePersistence(StatePersistence.Persisted)] class MyActor : Actor, IMyActor
          {
          public MyActor(ActorService actorService, ActorId actorId) base(actorService, actorId)
          {
          }
          public Task SetCountAsync(int value)
          {
          return this.StateManager.SetStateAsync<int>("MyState", value);
          }

              Explanation: Scenario: The chatbot greeting interface must match the formatting of the following example:
              AZ-202 dumps exhibit
              A message exchange between user and bot can contain one or more rich cards rendered as a list or carousel. The Attachments property of the Activity object contains an array of Attachment objects that represent the rich cards and media attachments within the message.
              The Bot Framework currently supports eight types of rich cards:
              Thumbnail Card. A card that typically contains a single thumbnail image, one or more buttons, and text.
              SignIn Card. A card that enables a bot to request that a user sign-in. It typically contains text and one or more buttons that the user can click to initiate the sign-in process.

              NEW QUESTION 12
              You are developing a NET Core on premises application that updates multiple Azure SQL Database instances. The application must log all update commands attempted to a separate Azure SQL Database instance named AuditDb.
              You define an outer TransactionScope with a loop to enumerate and run the SQL commands on each customer database connection and an inner TransactionScope to record transactions attempted within the outer TransactionScope to the AuditDb database.
              You need to develop a method to perform the updates to the databases. The solution must meet the following requirements:
              • All rows written to the AuditDb database must be committed even if the outer transaction fails.
              • If an error occurs writing to the AuditDb database, the outer transaction must be rolled back.
              • If an error occurs writing to the Customer databases, only the outer transaction must be rolled back.
              • Values for TransactionScopeOption must be specified for the customer databases.
              • Values for TransactionScopeOption must be specified for the AuditDb database. Which TransactionScopeOption values should you use?

              • A. Suppress for CustomerTranScopeOption and Required for AuditTranScopeOption
              • B. Required for the CustomerTranScopeOption and RequiresNew for the AuditTranScopeOption
              • C. RequiresNew for the CustomerTranScopeOption and RequiresNew for the AuditTranScopeOption
              • D. RequiresNew for CustomerTranScopeOption and Suppress for AuditTranScopeOption

              • A. Yes
              • B. No

              Answer: B

              Explanation: Use a custom outbound Azure API Management policy. Scenario:
              If a vendor is nearing the number of calls or bandwidth limit, the API must trigger email notifications to the vendor.
              (API usage must not exceed 5,000 calls and 50,000 kilobytes of bandwidth per hour per vendor.) References:

              You develop an entertainment application where users can buy and trade virtual real estate. The application must scale to support thousands of users.
              The current architecture includes five Azure Virtual Machines (VM) that connect to an Azure SQL Database for account information and Azure Table Storage for backend services. A user interacts with these components in the cloud at any given time
              - Routing Service – Routes a request to the appropriate service and must not persist data across sessions
              - Account Service – Stores and manages all account information and authentication and requires data to persist across sessions.
              - User Service – Stores and manages all user information and requires data to persist across sessions.
              - Housing Network Service – Stores and manages the current real-estate economy and requires data to persist across sessions.
              - Trade Service – Stores and manages virtual trade between accounts and requires data to persist across sessions.
              Due to volatile user traffic, a microservices solution is selected for scale agility.
              You need to migrate to a distributed microservices solution on Azure Service Fabric.
              Solution: Create a Service Fabric Cluster with a stateless Reliable Service for Routing Service. Create stateful Reliable Services for all other components.
              Does the solution meet the goal?

              • A. YES
              • B. NO

              Answer: A

              Explanation: We should use stateful services when we want data to persist, and stateless service when data must not persist. Note:
              For stateful services, the Reliable Services programming model allows you to consistently and reliably store your state right inside your service by using Reliable Collections.
              A stateless service is one where there is no state maintained within the service across calls. Any state that is present is entirely disposable and doesn't require synchronization, replication, persistence, or high availability.
