Topic 4, Scenario 4
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 Microsoft 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.
Application Structure
FlightInfo.cs
BlueYonderLoader.cs
HistoricalDataLoader.cs
MargiesTravelSync.cs
FlightInfoContext.cs
FlightDataController.cs
Q27. nbsp;Topic 1, Scenario 1
Background
You are developing an online bookstore web application that will be used by your company's customers.
Technical Requirements
General requirements:
. The web store application must be an ASP.NET MVC application written in Visual
Studio.
. The application must connect to a Microsoft SQL database.
. The GetTop100Books() method is mission critical and must return data as quickly
as possible. It should take advantage of fast forward-only, read-only methods of
reading data.
. The ImportBooks() method must keep a copy of the data that can be accessed
while new books are being imported without blocking reads.
. The CreateMonthlyTotalsReport() method must lock the data and prevent others
from updating or inserting new rows until complete.
. The college textbook area of the web application must get data from a daily
updated CSV file.
. The children's book area of the web application must get data directly from a local database. It must use a connection string. It must also support access to the stored procedures on the database. Further, it is required to have strongly typed objects. Finally, it will require access to databases from multiple vendors and needs to support more than one-to-one mapping of database tables.
. The cookbook functionality is contained within a client-side application that must connect to the server using HTTP and requires access to the data using JavaScript.
. The BookApiController class must have a method that is able to perform ad-hoc queries using OData.
The RESTful API of the bookstore must expose the following endpoints.
Application Structure
PurchaseOrders.xml
Featured Books.xml
(Topic 1)

D. LINQ to SQL
Answer: D
Q28. - (Topic 1)

Which method should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: A
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.cs
. ExternalQueueService.svc.
The ExternalQueue.Helpers namespace contains a definition for a class named OrderNotFoundException.
OrderProcessor Project:
Entity Framework is used for data access. The entities are defined in the 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:
. InboundQueueControIler.cs
. ProcessedOrderController.cs
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.cs
.UploadCallbackService.svc
Data Access is maintained in a file named UploadOrder.cs.
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.cs file. The POCO entity must be loaded by using lazy loading.
The project contains two services defined in the following files:
. IShippingService.cs
. 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
ExternalQueue\IExternalQueueService.cs
OrderProcessor\IExternalQueueService.svc
ExternalQueue\ProcessedOrderController.cs
OrderProcessor\InboundQueueController.cs
OrderUpload\IUploadCallbackService.cs
OrderUpload\UploadCallbackService.svc
Shipping\IShippingService.cs
Shipping\ShippingAddress.cs
Q29. - (Topic 5)
You are developing an ASP.NET MVC application.
You need to authenticate clients by using NT LAN Manager (NTLM).
Which authentication method should you implement?
A. Basic
B. Windows
C. Kerberos
D. Forms
Answer: B
Explanation: http://msdn.microsoft.com/en-us/library/aa292114(v=vs.71).aspx
Q30. - (Topic 5)
You are authoring unit tests.
The unit tests must test code that consumes sealed classes.
You need to create, maintain, and inject dependencies in the unit tests.
Which isolation method should you use?
A. Shim types
B. Hard-coded implementation
C. Stub types
D. T4 text templates and code generation
Answer: A
Explanation: http://msdn.microsoft.com/en-us/library/hh549176.aspx Shim types are one of two technologies that the Microsoft Fakes Framework uses to let you easily isolate components under test from the environment. Shims divert calls to specific methods to code that you write as part of your test. Many methods return different results dependent on external conditions, but a shim is under the control of your test and can return consistent results at every call. This makes your tests much easier to write.
