NEW QUESTION # 445
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.

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 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.

Metadata.Add example:
// Add metadata to the dictionary by calling the Add method
metadata.Add("docType", "textDocuments");
SetMetadataAsync example:
// Set the blob's metadata.
await blob.SetMetadataAsync(metadata);
// Set the blob's properties.
await blob.SetPropertiesAsync();

NEW QUESTION # 448
You are developing an ASP.NET Core website that uses Azure FrontDoor. The website is used to build custom weather data sets for researchers. Data sets are downloaded by users as Comma Separated Value (CSV) files. The data is refreshed every 10 hours.
Specific files must be purged from the FrontDoor cache based upon Response Header values.
You need to purge individual assets from the Front Door cache.
Which type of cache purge should you use?
Answer: C
Explanation:
These formats are supported in the lists of paths to purge:
* Single path purge: Purge individual assets by specifying the full path of the asset (without the protocol and domain), with the file extension, for example, /pictures/strasbourg.png;
* Wildcard purge: Asterisk (*) may be used as a wildcard. Purge all folders, subfolders, and files under an endpoint with /* in the path or purge all subfolders and files under a specific folder by specifying the folder followed by /*, for example, /pictures/*.
* Root domain purge: Purge the root of the endpoint with "/" in the path.

NEW QUESTION # 449
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.
