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 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.

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.

You need to configure settings to identify regional outages.
Which values should you use? To answer, drag the appropriate values to the correct settings. Each value may be used once, more than once, or mot 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.

Answer:

Explanation: Box 1, Probing interval: 10
Probing Interval. This value specifies how often an endpoint is checked for its health from a Traffic Manager probing agent. You can specify two values here: 30 seconds (normal probing)
and 10 seconds (fast probing). If no values are provided, the profile sets to a default value of 30 seconds.
Box 2: Tolerated Number of Failures: 3
Tolerated Number of Failures. This value specifies how many failures a Traffic Manager probing agent tolerates before marking that endpoint as unhealthy. Its value can range between 0 and 9. A value of 0 means a single monitoring failure can cause that endpoint to be marked as unhealthy. If no value is specified, it uses the default value of 3.
Scenario: Regional access to the Event Service API
Data for partners in Germany and Brazil must be served from Azure datacenters in their respective geographies unless there is a regional Azure outage. All other partners must use the US West Azure datacenter.
The solution will be highly available. You define regional Azure outages as periods of 60 seconds or more where the Event Service is not available.
