DRAG DROP
You are creating a WCF service. The service endpoints must be exposed to the Windows
Azure Service Bus. The service bus has a namespace named RestaurantSB. The key
provider is “owner”. You need to modify the web.config file to expose the endpoints. How
should you modify the file? (To answer, drag the appropriate attributes to the correct location
or locations in the answer area. Each attribute may be used once, more than once, or not at
all. You may need to drag the split bar between panes or scroll to view content.)

You are developing an ASP.NET MVC application. The application is an order processing
system that uses the ADO.NET Entity Framework against a SQL Server database. It has a
controller that loads a page that displays all orders along with customer information. Lazy
loading has been disabled. The Order class is shown below.

You need to return the orders and customer information in a single round trip to the
database. Which code segment should you use?

DRAG DROP
You are developing an ASP.NET Web API application for currency conversion that will be
consumed by a web browser by using a composite application that is served from another
web domain. You need to configure the Web API. What should you do? (To answer, drag
the appropriate XML elements to the correct location or locations in the answer area. Each
XML element may be used once, more than once, or not at all. You may need to drag the
split bar between panes or scroll to view content.)

You are developing an ASP.NET MVC application that reads and writes data from a SQL
Server database. You need to maintain data integrity in all situations that use transactions.

HOTSPOT
You are supporting an application that uses the ADO.NET Entity Framework to query and
access data. The latest version of Entity Framework contains bug fixes that will improve
performance. You need to update Entity Framework. Which Visual Studio 2012 menu item
should you choose? (To answer, select the appropriate menu item in the answer area.)

You are developing an ASP.NET MVC application. Deployment administrators do not have
access to Visual Studio 2102, but will have the elevated permissions required to deploy the
application to the servers. You need to select a deployment tool for use by the deployment
administrators. Which tool should you use?

Scenario 1
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.

Errors occasionally occur when saving data using the FlightInfoContext ADO.NET Entity
Framework context. Updates to the data are being lost when an error occurs. You need to
ensure that data is still saved when an error occurs by retrying the operation. No more than
five retries should be performed. Which code segment should you use as the body of the
SaveChanges() method in the FlightInfoContext.es file?
