Q6. You are developing an ASP.NET MVC application by using Visual Studio 2012.

The application throws and handles exceptions when it runs.

You need to examine the state of the application when exceptions are thrown. What should you do?

A. From the Debug menu in Visual Studio 2012, select Exceptions. Enable the Thrown check box for Common Language Runtime Exceptions.

B. From the DEBUG menu in Visual Studio 2012, select Attach to Process. Select the IIS process.

C. From the Debug menu in Visual Studio 2012, select Exceptions. Disable the User- unhandled check box for Common Language Runtime Exceptions.

D. From the TOOLS menu in Visual Studio 2012, click Customize. Click the Command tab and select Debug.

Answer: A

Explanation:

Configuring the debugger to break for first chance exceptions

To change when the debugger breaks, go to Debug->Exceptionsu2026

When you first open this window you will see that there is a tree grid with one column and checkboxes.

* Break when Thrown. This includes a default list of exceptions known by the debugger, grouped by category.

Note: The possible exceptions that could break from this list is determined by the runtime you are debugging. For example, if you are using managed-only debugging then the debugger will never break for C++, Win32 Exceptions, etc. even if they are configured to break when thrown.

* Checkboxes. If you check the box for a category, then the debugger will break for all First Chance Exceptions while debugging. If you donu2021t want to enable all First Chance Exceptions, you can find the specific exception types that you wish to configure by using the search box.

Q7. You are implementing a website redesign of an existing website that provides historical weather condition maps. The current layout resembles the following graphic.

Year selection is implemented as a set of links, which causes the page to reload when the user changes the year. The year selection HTML is contained in a div with an id of "year- changer".

You need to modify the page so that the user can change the year without the page reloading. You also need to ensure that there is minimal change to the design of the page.

Which code segment should you use?

A. Option A

B. Option B

C. Option C

D. Option D

Answer: B

Explanation:

jQuery code will bind the slider control to the div.

$(document).ready(function(){

$("#slider").slider();

});

Now, when you run this page then you will see a long slider on page with no range. As we have not specified any range.slider control comes with various options/properties which

can be set. Here are few of them.

1. min : Minimum value allowed for the slider.

2. max : Maximum allowed value for the slider.

3. step : How much you want to increment when you slide. Default is 1.

4. value : set default value of the slider. References:

Q10. You are developing an ASP.NET MVC application that uses forms authentication against a third-party database.

You need to authenticate the users. Which code segment should you use?

A. Option A

B. Option B

C. Option C

D. Option D

Answer: D

Explanation:

ASP.NET membership is designed to enable you to easily use a number of different membership providers for your ASP.NET applications.

There are two primary reasons for creating a custom membership provider.

* You need to store membership information in a data source that is not supported by the membership providers included with the .NET Framework, such as a FoxPro database, an Oracle database, or other data sources.

* You need to manage membership information using a database schema that is different from the database schema used by the providers that ship with the .NET Framework.

To implement a membership provider, you create a class that inherits the MembershipProvider abstract class from the System.Web.Security namespace.

Incorrect:

Not C: Class ProviderBase

The provider model is intended to encapsulate all or part of the functionality of multiple ASP.NET features, such as membership, profiles, and protected configuration.

Q11. 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 Session on the server

B. In a cookie stored in the browser

C. In ViewData in the application

D. In TempData on the server

Answer: A,B

Explanation:

Server sessions and cookies can both be configured to secure and they both persist after the users log on.

Incorrect:

Not C: ViewData's life only lasts during current http request.

Not D: TempData is a bucket where you can dump data that is only needed for the following request. That is, anything you put into TempData is discarded after the next request completes.

Q12. You develop an ASP.NET MVC application. The application has a controller named PeopleController.cs. The controller has an action method that returns a parent view. The parent view includes the following code. Line numbers are included for the reference only.

The application also contains a partial view named People. The parent view must display the partial view.

You need to add code at line 09 to display the partial view within the parent view.

Which two code segments will achieve the goal? Each correct answer presents a complete solution.

A. @{ Html.RenderPartial(u201cPeopleu201d, Model);}

B. @Html.Partial(u201cPeopleu201d, Model)

C. @Html.Display(u201cPeopleu201d, Model)

D. @Html.Raw(u201cPeopleu201d)

Answer: B

Explanation:

By default, any partial view rendered by calling @Html.Partial("PartialViewName") will get the view model passed to the parent view.

Q13. You are developing an ASP.NET MVC web application for viewing a list of contacts. The application is designed for devices that support changes in orientation, such as tablets and smartphones. The application displays a grid of contact tiles in portrait mode.

When the orientation changes to landscape, each tile in the grid expands to include each contact's details. The HTML that creates the tiled interface resembles the following markup.

The CSS used to style the tiles in landscape mode is as follows.

If this CSS is omitted, the existing CSS displays the tiles in portrait mode.

You need to update the landscape-mode CSS to apply only to screens with a width greater than or equal to 500 pixels.

Which code segment should you use?

A. @media screen and (width >= 500px) {u2026}

B. @media screen and (min-width: 500px) {u2026}

C. @media screen(min-width: 500px, max-width: 1000px) {u2026}

D. @media resolution(min-width: 500px) {u2026}

Q14. You are developing an ASP.NET MVC web application in Visual Studio 2012. The application requires several thousand content files. All content is hosted on the same IIS

instance as the application.

You detect performance issues when the application starts. You need to resolve the performance issues.

What should you do?

A. Implement HTTP caching in the ASP.NET MVC controllers.

B. Combine the content files by using ASP.NET MVC bundling.

C. Install a second IIS instance.

D. Move the content to a Windows Azure CDN.

Answer: B

Explanation:

Bundling is a new feature in ASP.NET 4.5 that makes it easy to combine or bundle multiple files into a single file. You can create CSS, JavaScript and other bundles. Fewer files means fewer HTTP requests and that can improve first page load performance.

Q15. You are developing an ASP.NET MVC application that uses forms authentication. The user

database contains a user named OrderAdmin. You have the following requirements:

You need to implement the controller to meet the requirements.

Which code segment should you use? (Each correct answer presents a complete solution. Choose all that apply.)

A. Option A

B. Option B

C. Option C

D. Option D

Answer: B

Explanation:

With MVC4 a new attribute has been introduced, namely the [AllowAnonymous] attribute. Together with the [Authorize] attribute, you can now take a white-list approach instead. The white-list approach is accomplished by dressing the entire controller with the [Authorize] attribute, to force authorization for all actions within that controller. You can then dress specific actions, that shouldn't require authorization, with the [AllowAnonymous] attribute, and thereby white-listing only those actions. With this approach, you can be confident that you don't, by accident, forget to dress an action with the [Authorize], leaving it available to anyone, even though it shouldn't.
