NEW QUESTION 3
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);
}
}

Topic 2, Chatbot
Background
Best for You Organics Company is a global restaurant franchise that has multiple locations. The company wants to enhance user experiences and vendor integrations. The company plans to implement automated mobile ordering and delivery services.
Best For You Organics hosts an Azure web app at the URL https://www.bestforyouorganics.com.
Users can use the web app to browse restaurant locations, menu items, nutritional, information, and company information. The company developed and deployed a cross-platform mobile app.
Requirements
You must develop a chartbot by using the Bot Builder SDK and Language Understanding Intelligence Service (LUIS). The chatbot must allow users to order food for pickup or delivery.
The chatbot must meet the following requirements:
Ensure that chatbot endpoint can be accessed only by the Bot Framework connector.
Use natural language processing and speech recognition so that users can interact with the chatbot by using text and voice. Processing must be server-based.
Alert users about promotions at local restaurants.
Enable users to place an order for delivery or pickup by using their voice.
Greet the user upon sigh-in by displaying a graphical interface that contains action buttons.
The chatbot greeting interface must match the formatting of the following example:
Vendor API
Vendors receive and provide updates for the restaurant inventory and delivery services by using Azure API Management hosted APIs. Each vendor uses their own subscription to access each of the APIs.
APIs must meet the following conditions:
API usage must not exceed 5,000 calls and 50,000 kilobytes of bandwidth per hour per vendor.
If a vendor is nearing the number of calls or bandwidth limit, the API must trigger email notifications to the vendor.
APIs must prevent API usage spikes on a per-subscription basis by limiting the call rate to 100 calls per minute.
The Inventory API must be written by using ASP.NET Core and Node.js.
The API must be updated to provide an interface to Azure SQL Database. Database objects must be managed by using code.
The Delivery API must be protected by using the OAuth 2.0 protocol with Azure Active Directory (Azure AD) when called from the Azure web app. You register the Delivery API and web app in Azure AD. You enable OAuth 2.0 in the web app.
The delivery API must update the Products table, the Vendor transactions table, and the Billing table in a single transaction.
The Best For You Organics Company architecture team has created the following diagram depicting the expected deployments into Azure:
Delivery API
The Delivery API intermittently throws the following exception:
Chatbot greeting
The chatbot’s greeting does not show the user’s name. You need to debug the chatbot locally.
Language processing
Users report that the bot fails to understand when a customer attempts to order dishes that use Italian names. Relevant portions of the app files are shown below. Line numbers are included for reference only and include a two-character prefix that denotes the specific file to which they belong.

NEW QUESTION 8
You need to resolve a notification latency issue.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point
Answer: AD
Explanation: Azure Functions can run on either a Consumption Plan or a dedicated App Service Plan. If you run in a dedicated mode, you need to turn on the Always On setting for your Function App to run properly. The Function runtime will go idle after a few minutes of inactivity, so only HTTP triggers will actually "wake up" your functions. This is similar to how WebJobs must have Always On enabled.
Scenario: Notification latency: Users report that anomaly detection emails can sometimes arrive several minutes after an anomaly is detected.
Anomaly detection service: You have an anomaly detection service that analyzes log information for anomalies. It is implemented as an Azure Machine Learning model. The model is deployed as a web service.
If an anomaly is detected, an Azure Function that emails administrators is called by using an HTTP WebHook. References:

NEW QUESTION 13
You need to resolve the delivery API error. What should you do?
Answer: A
Explanation: Scenario: The Delivery API intermittently throws the following exception:
A useful method to get rid of this error is to use RETRY LOGIC of Entity Framework 1.1.0 services.AddDbContext<DbContext>(options => options.UseSqlServer('yourconnectionstring',
…sqlServerOptionsAction: sqlOptions =>
…{
……sqlOptions.EnableRetryOnFailure(
………maxRetryCount: 5,
………maxRetryDelay: TimeSpan.FromSeconds(30),
………errorNumbersToAdd: new List<int>() { 19 });
…}));
In Retry logic, error 19 is not included. So you have to pass the error code 19 to set retry logic for error code 19.
