  2. 70-487 Section 1: Sec One (1 to 16) Details: Topic 1, Flight Information Background You are developing a flight information consolidation service. The service retrieves flight information from a number of sources and combines them into a single data set. The consolidated flight information is stored in a SQL Server database. Customers can query and retrieve the data by using a REST API provided by the service. The service also offers access to historical flight information. The historical flight information can be filtered and queried in an ad hoc manner. The service runs on a Windows Azure Web Role. SSL is not used. Business Requirements ✑ A new data source for historical flight information is being developed by a contractor located on another continent. ✑ If a time zone is not specified, then it should be interpreted as Coordinated Universal Time (UTC). ✑ When you upgrade a service from a staging deployment to a production deployment, the time that the service is unavailable must be minimized. ✑ The default port must be used for HTTP. Technical Requirements The existing sources of flight information and the mechanism of exchange are listed below. ✑ Blue Yonder Airlines provides flight information in an XML file. ✑ Consolidated Messenger provides flight information in a Microsoft Access database that is uploaded every 12 hours to the service using SFTP. The company uses port 22 for SFTP. ✑ Margie's Travel provides and consumes flight information using serialized ADO.NET DataSets. Data is periodically synced between the service and Margie's Travel. ✑ Trey Research provides data from multiple sources serialized in proprietary binary formats. The data must be read by using .NET assemblies provided by Trey Research. The assemblies use a common set of dependencies. The current version of the Trey Research assemblies is 1.2.0.0. All assemblies provided by Trey Research are signed with a key pair contained in a file named Trey.snk, which Trey Research also supplies. ✑ The application specification requires that any third-party assemblies must have strong names.

Section 2: Sec Two (17 to 47) Details: Topic 2, ASP.NET MVC 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. OrderProcessor Project: Entity Framework is used for data access. The entities are defined in the 21 http://www.troytec.com

  22. 70-487 ProcessedOrders.edmx file as shown in the following diagram. 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. 22 http://www.troytec.com
