Question 161
You are a developer for a Software as a Service (SaaS) company. You develop solutions that provide the ability to send notifications by using Azure Notification Hubs.
You need to create sample code that customers can use as a reference for how to send raw notifications to Windows Push Notification Services (WNS) devices. The sample code must not use external packages.
How should you complete the code segment? 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.
Question 162
You are developing a ticket reservation system for an airline.
The storage solution for the application must meet the following requirements:
* Ensure at least 99.99% availability and provide low latency.
* Accept reservations event when localized network outages or other unforeseen failures occur.
* Process reservations in the exact sequence as reservations are submitted to minimize overbooking or selling the same seat to multiple travelers.
* Allow simultaneous and out-of-order reservations with a maximum five-second tolerance window.
You provision a resource group named airlineResourceGroup in the Azure South-Central US region.
You need to provision a SQL SPI Cosmos DB account to support the app.
How should you complete the Azure CLI commands? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Question 163
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 question, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You are developing a solution that will be deployed to an Azure Kubernetes Service (AKS) cluster. The solution will include a custom VNet, Azure Container Registry images, and an Azure Storage account.
The solution must allow dynamic creation and management of all Azure resources within the AKS cluster.
You need to configure an AKS cluster for use with the Azure APIs.
Solution: Create an AKS cluster that supports network policy. Create and apply a network to allow traffic only from within a defined namespace.
Does the solution meet the goal?
Question 164
You need to ensure that the solution can meet the scaling requirements for Policy Service.
Which Azure Application Insights data model should you use?
Question 165
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.
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.
Startup.cs
You need to implement the purchase requirement.
