Testlet 1

Topic 2, Scenario 2

Background

You are developing an ASP.NET MVC application in Visual Studio 2012 that will be used to

process orders.

Business Requirements

The application contains the following three pages.

A page that queries an external database for orders that are ready to be

processed. The user can then process the order.

A page to view processed orders.

A page to view vendor information.

The application consumes three WCF services to retrieve external data.

Technical Requirements

Visual Studio Solution:

The solution contains the following four projects.

ExternalQueue: A WCF service project used to communicate with the

external order database.

OrderProcessor: An ASP.NET MVC project used for order processing and

logging order metadata.

OrderUpload: A WCF service project used to submit order data to an

external data source.

Shipping: A WCF service project used to acquire shipping information.

ExternalQueue Project:

Entity Framework is used for data access. The entities are defined in the ExternalOrders.edmx

file as shown in the following diagram.

The project contains two services defined in the following files.

IExternalQueueService.es

ExternalQueueService.svc.

The ExternalQueue.Helpers namespace contains a definition for a class named OrderNotFound

Exception.

The classes are contained in the OrderProcessor.Entities namespace. The project contains the

following two controllers.

InboundQueueController.es

ProcessedOrderController.es

WCF service proxies to the ExternalQueue, Shipping and OrderUpload services have been

generated by using the command prompt. The ExecuteCommandProcedure() method in the

ExternalQueueService.svc file must run asynchronously.

The ProcessedOrderController controller has the following requirements.

The GetVendorPolicy() method must enforce a 10 minute absolute cache expiration policy.

The GetProcessedOrders() method must return a view of the 10 most recently processed orders.

OrderUpload Project:

The project contains two services defined in the following files.

IUploadCallbackService.es

UploadCallbackService.svc

Data Access is maintained in a file named UploadOrder.es.

Shipping Project:

Entity Framework is used for data access. The entities are defined in the ExternalOrders.edmx

file as shown in the following diagram

The Custom Tool property for ExternalOrders.edmx has been removed.

POCO classes for the Entity Model are located in the ShippingAddress.es file. The POCO entity

must be loaded by using lazy loading.

The project contains two services defined in the following files.

IShippingService.es

ShippingService.svc.

The IShippingService contract must contain an operation that receives an order number as a

parameter. The operation must return a class named ShippingInfo that inherits from a class

named State.

Application Structure

QUESTION NO:13

The GetQueueItems() action in the InboundQueueController controller is not populating the

view with data. The action must populate the view with data by calling the GetExternalOrders()

method in the ExternalQueueService service using the ChannelFactory class.

You need to modify the action to populate the view with data.

What should you do? (To answer, drag the appropriate code segments to the correct location or

locations in the answer area. Each code segment may be used once, more than once, or not at all.

by flight name.

You need to specify which properties of the FlightInfo class should be used at the partition and

row keys to ensure that query results are returned as quickly as possible.
