NEW QUESTION NO: 12
You are developing an ASP.NET MVC application.
The application must allow users to enter JavaScript in a feedback text box only.
You need to disable request validation.
What should you do?
A. Apply and set the CausesClientSideValidation attribute on the text box to FALSE.
B. Apply and set the ValidateInput attributeon the text box to FALSE.
C. Use the HttpRequest.Unvalidated property to read the unvalidated form value.
D. Use the HttpRequest.Form property to read the unvalidated form value.
Answer: C
Explanation/Reference:
Explanation:
The HttpRequest.Unvalidated property gets the HTTPrequest values without triggering request validation.
Request validation checks for HTML markup and script that might indicate a potential cross-site scripting attack. By default, all values are checked using request validation and if any values contain markup or script, ASP.NET throws an HttpRequestValidationException exception. Use this method if you anticipate that the request will contain markup (for example, you are allowing users to post content that contains markup) and you want to get the raw value of a request.

Testlet 1
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 administrators 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 Windows 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 perf 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.

NEW QUESTION NO: 17
You are developing an ASP.NET MVC application to be used on the Internet. The environment uses Active Directory with delegation to access secure resources.
Users must be able to log on to the application to maintain their personal preferences.
You need to use the least amount of development effort to enable users to log on.
What should you do?
A. Enable Forms authentication
B. Enable Windows authentication
C. Generate server SSL certificates and install them in IIS
D. Enable Digest authentication
Answer: B
Explanation/Reference:
Explanation:
Requirements for Delegation
Delegation relies on Integrated Windows authentication to access resources. There is no limit on the number of computers that you can delegate your account -- you must correctly configure each of them.
The Integrated Windows authentication method works only if the following two conditions exist:
/You set up your network to use the Kerberos authentication protocol that requires Active Directory.
/You set up the computers and accounts on your network as trusted for delegation.

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 withthe .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.

Configuring the debugger to break for first chance exceptions
To change when the debugger breaks, go to Debug->Exceptions...

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 don't want to enable all First Chance Exceptions, you can find the specific exception types that you wish to configure by using the search box.

NEW QUESTION NO: 20
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.
