Q11. DRAG DROP - (Topic 4)
You are developing an ASP.NET MVC application in a web farm. The application has a page that uploads a customer's photo, resizes it, and then redirects the browser to a page where the new image is displayed along with the final dimensions.
The final dimensions should be available only to the page where the new image is displayed.
You need to store state and configure the application.
What should you do? (To answer, drag the appropriate item to the correct location. Each item 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.)

Q12. - (Topic 4)
You are developing an ASP.NET MVC web application for viewing a photo album. The application is designed for devices that support changes in orientation, such as tablets and smartphones. The application displays a grid of photos in portrait mode.
When the orientation changes to landscape, each tile in the grid expands to include a description. The HTML that creates the gallery interface resembles the following markup.
If this CSS is omitted, the existing CSS displays the tiles in landscape mode.
You need to update the portrait mode CSS to apply only to screens with a width less than 500 pixels.
Which code segment should you use?
A. @media resolution(max-width: 500px) {
. . .
}
B. @media screen(min-width: Opx, max-width: 500px) {
. . .
}
C. @media screen and (width <= 500px) {

Q15. Topic 1, Olympic Marathon
Background
You are developing an ASP.NET MVC application in Visual Studio 2012 that will be used by Olympic marathon runners to log data about training runs.
Business Requirements
The application stores date, distance, and duration information about a user's training runs. The user can view, insert, edit, and delete records.
The application must be optimized for accessibility.
All times must be displayed in the user's local time.
Technical Requirements
Data Access:
Database access is handled by a public class named
RunnerLog.DataAccess.RunnerLogDb.
All data retrieval must be done by HTTP GET and all data updates must be done by HTTP
POST.
Layout:
All pages in the application use a master layout file named \Views\Shared\_Layout.cshtml.
Models:
The application uses the \Models\LogModel.cs model.
Views:
All views in the application use the Razor view engine.
Four views located in \Views\RunLog are named: _CalculatePace.cshtml EditLog.cshtml GetLog.cshtml InsertLog.cshtml
The application also contains a \Views\Home\Index.cshtml view.
Controllers:
The application contains a \Controllers\RunLogController.cs controller.
Images:
A stopwatch.png image is located in the \Images folder.
Videos:
A map of a runner's path is available when a user views a run log. The map is implemented
as an Adobe Flash application and video. The browser should display the video natively if possible, using H264, Ogg, or WebM formats, in that order. If the video cannot be displayed, then the Flash application should be used.
Security:
You have the following security requirements: The application is configured to use forms authentication. Users must be logged on to insert runner data. Users must be members of the Admin role to edit or delete runner data. There are no security requirements for viewing runner data. You need to protect the application against cross-site request forgery. Passwords are hashed by using the SHA1 algorithm.
RunnerLog.Providers.RunLogRoleProvider.cs contains a custom role provider.
Relevant portions of the application files follow. (Line numbers are included for reference only.)
Application Structure
- (Topic 1)
You need to ensure that the application uses RunLogRoleProvider custom role provider.
How should you modify the web.config file? (To answer, drag the appropriate line of code to the correct location or locations. Each line of code 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.)
Answer:
Q16. - (Topic 4)
You are developing an application that uses many small images for various aspects of the interface.
The application responds slowly when additional resources are being accessed.
You need to improve the performance of the application.
What should you do?
A. Preload all the images when the client connects to ensure that the images are cached.
B. Combine all the images into a single image and use CSS to create sprites.
C. Host all images on an alternate server and provide a CDN.
D. Convert the images to .png file format and stream all images on a single connection.
Answer: C
Q17. - (Topic 4)
You are designing an MVC web application.
The view must be as simple as possible for designers who do not have a technical
background.
You need to combine two existing models to meet the requirement.
Which component of the MVC framework should you use?
A. View
B. View Model
C. Controller
D. Model
Answer: B
Q18. - (Topic 4)
You are designing a distributed application.
The application must store secure information that is specific to an individual user. The data must be automatically purged when the user logs off.
You need to save transient information in a secure data store.
Which data store should you use?
A. Session state
B. Database storage
C. Profile properties
D. Application state
Answer: B
Q19. - (Topic 2)
You are designing a Windows Communication Foundation (WCF) service that uses the Product class.
You need to update the class to meet the storage requirement.
What should you do? (Each correct answer presents part of the solution. Choose all that apply.)
A. Mark the Product class with the DataContract attribute.
B. Mark the public members of the Product class with the DataContractFormat attribute.
C. Mark the Product class with the CollectionDataContract attribute.
D. Mark the public members of the Product class with the DataMember attribute.
Answer: A,D
Explanation: So as of .NET 3.5 SP1, you don't have to add data contract or data member
attributes anymore - if you don't then the data contract serializer will serialize all public
properties on your class, just like the XML serializer would.
HOWEVER: by not adding those attributes, you lose a lot of useful capabilities:
. without [DataContract], you cannot define an XML namespace for your data to live
in . without [DataMember], you cannot serialize non-public properties or fields . without [DataMember], you cannot define an order of serialization (Order=) and the
DCS will serialize all properties alphabetically . without [DataMember], you cannot define a different name for your property (Name=) . without [DataMember], you cannot define things like IsRequired= or other useful attributes . without [DataMember], you cannot leave out certain public properties - all public properties will be serialized by the DCS
Q20. - (Topic 3)
You need to ensure that developers can connect to a Windows Azure role by using RDP.
What should you do?
A. Export a certificate without a private key. Upload the .cer file to the Management Certificates section on the Azure Management Portal.
B. Export a certificate with a private key. Upload the .pfx file to the Management Certificates section on the Azure Management Portal.
C. Export a certificate without a private key. Upload the .cer file to the Certificates section under the TranscodeWorkerRole hosted service on the Azure Management Portal.
D. Export a certificate with a private key. Upload the .pfx file to the Certificates section under the TranscodeWorkerRole hosted service on the Azure Management Portal.
Answer: D
