Q72. - (Topic 4)
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: 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.
Q73. - (Topic 4)
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
Q74. - (Topic 4)
You are developing an ASP.NET MVC application. The application is deployed in a web farm and is accessed by many users.
The application must handle web server failures gracefully. The servers in the farm must share the state information.
You need to persist the application state during the session.
What should you implement?
A. A state server
B. Cookieless sessions
C. A web garden on the web servers
D. An InProc session
Answer: A
Q75. - (Topic 4)
You are designing a distributed application that runs on the Windows Azure platform.
The application must store a small amount of insecure global information that does not change frequently.
You need to configure the application to meet the requirements.
Which server-side state management option should you use? (Each correct answer presents a complete solution. Choose all that apply.)
A. Windows Azure application state
B. SQL Azure
C. Profile properties of the Windows Azure application
D. Windows Azure session state
Answer: B,D
Explanation: SQL Database provides a relational database management system for Windows Azure and is based on SQL Server technology. With a SQL Database instance, you can easily provision and deploy relational database solutions to the cloud, and take advantage of a distributed data center that provides enterprise-class availability, scalability, and security with the benefits of built-in data protection and self-healing.
Session States in Windows Azure.
If you are a Web developer, you are probably very familiar with managing user state - that is you are familiar with tracking user activity and actions across several request-response exchanges that occur in Web applications. Since HTTP is a stateless protocol, developers over the years have developed all sorts of means to manage state. You'll even find an MSDN page providing alternatives and recommendations for state management here. Cookies, hidden fields, and query strings are some client-side options to tracking user state. When it comes to managing that state on the server-side, most Web developers rely on session objects.
Q76. DRAG DROP - (Topic 4)
You are developing an ASP.NET MVC application in Visual Studio. The application contains sensitive bank account data.
The application contains a helper class named SensitiveData.Helpers.CustomEncryptor.
The application contains a controller named BankAccountController with two actions.
The application contains a model named BankAccount, which is defined in the following code segment.
The application must not display AccountNumber in clear text in any URL.
You need to build the view for the GetAccounts action.
You have the following code:
Which code segments should you include in Target 1, Target 2 and Target 3 to build the view? To answer, drag the appropriate code segment to the correct targets. 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.

Answer: A,D
Topic 3, Video Transcoding Service
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.

Q80. - (Topic 4)
You need to enable client-side validation for an ASP.NET MVC application.
Which three actions should you perform? Each correct answer presents part of the solution.
A. Attach a custom validation attribute to the model properties that the view uses.
B. Reference the jquery, jquery.validate and jquery.validate.unobtrusive script files in the view.
C. Open the web.config file at the project root, and set the values of the ClientValidationEnabled and UnobtrusiveJavaScriptEnabled keys to True.
D. For each form element, use the Validator.element() method to validate each item.
E. Add data annotations to the model properties that the view uses.
Answer: B,C,E
Explanation: B: . The validation can be implemented using jQuery and jQuery validation plug-in (jquery.validate.min.js and jquery.validate.unobtrusive.min.js).
C: When you are developing an MVC application in Visual Studio 2012 then the client-side
becomes enabled by default, but you can easily enable or disable the writing of the
following app setting code snippet in the web.config file.
<configuration>
<appSettings>
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>
</configuration>
E: The jQuery validation plug-in takes advantage of the Data Annotation attributes defined in the model, which means that you need to do very little to start using it.
