Topic 3, Scenario 3
Background
You are developing a video transcoding service. This service is used by customers to upload video files, convert video to other formats, and view the converted files. This service is used by customers all over the world.
Business Requirements
The user-facing portion of the application is an ASP.NET MVC application. It provides an interface for administrators to upload video and schedule transcoding. It also enables administrations and users to download the transcoded videos.
When videos are uploaded, they are populated with metadata used to identify the video. The video metadata is gathered by only one system when the video upload is complete.
Customers require support for Microsoft Internet Explorer 7 and later.
The application contains a header that is visible on every page.
If the logged-on user is an administrator, then the header will contain links to administrative functions. This information is read from a cookie that is set on the server. The administrative links must not be present if an error condition is present
Technical Requirements
User Experience:
. The front-end web application enables a user to view a list of videos.
. The main view of the application is the web page that displays the list of videos.
. HTML elements other than the list of videos are changed with every request requiring the page to reload.
Compatibility:
Some customers use browsers that do not support the HTTP DELETE verb.
These browsers send a POST request with an HTTP header of X-Delete when the intended action is to delete.
Transcoding:
The video transcoding occurs on a set of Microsoft Azure worker roles.
The transcoding is performed by a third-party command line tool named transcode.exe. When the tool is installed, an Environment variable named transcode contains the path to the utility.
A variable named license contains the license key. The license for the transcoding utility requires that it be unregistered when it is not in use.
The transcoding utility requires a significant amount of resources. A maximum of 10 instances of the utility can be running at any one time. If an instance of the role cannot process an additional video, it must not prevent any other roles from processing that video.
The utility logs errors to a Logs directory under the utilities path.
A local Azure directory resource named pert is used to capture performance data.
Development:
Developers must use Microsoft Remote Desktop Protocol (RDP) to view errors generated by the transcode.exe utility.
An x509 certificate has been created and distributed to the developers for this purpose.
Developers must be able to use only RDP and not any other administrative functions.

Q21. - (Topic 5)
You are developing an ASP.NET MVC application that uses forms authentication to verify that the user is logged in.
Authentication credentials must be encrypted and secure so no user identity is exposed.
You need to ensure that user credentials are persisted after users log on.
Where should you store the credentials? (Each correct answer presents a complete solution. Choose all that apply.)
A. In TempData on the server
B. In a cookie stored in the browser
C. In ViewData in the application
D. In Session on the server
Answer: B,D
Q22. DRAG DROP - (Topic 5)

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
