Case Study 4 - Best for You Organics
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 sign-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.

Note: In this section you will see one or more sets of questions with the same scenario and problem. Each question presents a unique solution to the problem, and you must determine whether the solution meets the stated goals. More than one solution might solve the problem. It is also possible that none of the solutions solve the problem.
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.
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution. Determine whether the solution meets the stated goals.
You need to meet the vendor notification requirement.
Solution: Create and apply a custom outbound Azure API Management policy.
Does the solution meet the goal?

You are configuring a development environment for your team. You deploy the latest Visual Studio image from the Azure Marketplace to your Azure subscription.
The development environment requires several software development kits (SDKs) and third-party components to support application development across the organization. You install and customize the deployed virtual machine (VM) for your development team. The customized VM must be saved to allow provisioning of a new team member development environment.
You need to save the customized VM for future provisioning.
Which tools or services should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

You are developing a REST web service. Customers will access the service by using an Azure API Management instance.
The web service does not correctly handle conflicts. Instead of returning an HTTP status code of 409, the service returns a status code of 500. The body of the status message contains only the word conflict.
You need to ensure that conflicts produce the correct response.
How should you complete the policy? To answer, drag the appropriate code segments to the correct locations. Each code segment 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.
