Case Study 1 – Scenario 1 (Question 1 – Question 7)
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 Create MonthlyTotalsReport() 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.

You have the following code:
17
Which code segments should you include in Target 1 and Target 2 to complete the code? (To answer, drag the appropriate code segments to the correct targets in the answer area. Each code segment 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.)
18
Answer:
19

QUESTION 2
You need to choose the appropriate data access strategy for the college textbook area of the web application.
Which data access technology should you implement?

A.    WCF Data Services
B.    ADO.NET
C.    Entity Data Model (EDM)
D.    LINQ to SQL

Answer: B
Explanation:
* Scenario: The college textbook area of the web application must get data from a daily updated CSV file.
* ADO.NET reads the CSV file in a very similar way as table in database.

QUESTION 3
You need to choose the appropriate data access technology for the children’s book area of the web application.
Which data access technology should you choose?

A.    ADO.NET Entity Framework
B.    Web Service
C.    LINQ to SQL
D.    WCF Data Services

Answer: C
Explanation:
* Scenario: 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.
* Microsoft Language Integrated Query (LINQ) offers developers a new way to query data using strongly-typed queries and strongly-typed results, common across a number of disparate data types including relational databases, .NET objects, and XML. By using strongly-typed queries and results, LINQ improves developer productivity with the benefits of IntelliSense and compile-time error checking

QUESTION 4
You need to implement the Get() method in the bookstore Web API application to be able to find books by using an ad hoc query.
Which method should you use?
41

A.    Option A
B.    Option B
C.    Option C
D.    Option D

Answer: A

QUESTION 5
You are developing an ASP.NET MVC application that is secured using SSL.
You are ready to deploy the application to production.
The deployment package must include the installation of the SSL certificate.
You need to configure the deployment package to meet the requirement.
What should you do?

A.    In the Package/Publish settings of the project, select the All Files in this project folder option.
B.    In the Build Events settings of the project, configure a pre-build event to include the SSL certificate.
C.    Create a web publish pipeline target file with a custom web deploy target.
D.     In the Signing dialog box, choose Sign the assembly and select the appropriate entry from the Choose a strong name key file list.

Answer: C

QUESTION 6
You need to choose the appropriate data access technology for the cookbook area of the web application.
Which data access technology should you choose?

A.    Entity Framework
B.    ADO.NET
C.    LINQ to SQL
D.    WCF Data Services

Answer: D
Explanation:
* Scenario: 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.
* WCF Data Services (formerly known as “ADO.NET Data Services”) is a component of the .NET Framework that enables you to create services that use the Open Data Protocol (OData) to expose and consume data over the Web or intranet by using the semantics of representational state transfer (REST). OData exposes data as resources that are addressable by URIs. Data is accessed and changed by using standard HTTP verbs of GET, PUT, POST, and DELETE
* WCF Data Services uses the OData protocol for addressing and updating resources. In this way, you can access these services from any client that supports OData. OData enables you to request and write data to resources by using well-known transfer formats:
Atom, a set of standards for exchanging and updating data as XML, and JavaScript Object Notation (JSON), a text-based data exchange format used extensively in AJAX application.

QUESTION 7
You are preparing to write the data access code for the children’s book area of the web site.
You need to review the requirements and identify the appropriate data access technology.
What should you do?

A.    Use the WCF Data Services.
B.    Use a Web Service.
C.    Use ADO.NET Entity Framework.
D.    Use LINQ to SQL

Answer: C

Case Study 2 – Scenario 2 (Question 8 – Question 13)
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.
71
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.
72
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.
73
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.

Case Study 3 – Scenario 3 (Question 14 – Question 21)
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.
