1. 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.

3 / 76 
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.)

displayed. 
You need to display the date of the run according to the business requirements. 
Which code segment should you use? 
A. @Html.DisplayFor(model => log.ShortDate) 
B. @log.RunDate.ToString() 
C. @log.RunDate.ToShortDateString() 
D. @Html.DisplayFor(model => log.RunDate) 
Answer: A 
Explanation: 
The log file has the ShortDate function which is defined as: 
Return RunDate.ToLocalTime().ToShortDateString(); 
This meets the requirement. 
Note: 
Scenario: 
* The application uses the \Models\LogModel.cs model. 
* The Html.DisplayFor method is typically used to display values from the object that is exposed by the 
Model property. 
The DisplayExtensions.DisplayFor<TModel, TValue> method (HtmlHelper<TModel>, 
Expression<Func<TModel, TValue>>) 
Returns HTML markup for each property in the object that is represented by the Expression expression. 
Incorrect: 
Not D: The RunDate attribute is defined as DateTime, but the timestamp (the time of day), should not be 
displayed.

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:

44 / 76 
Explanation: 
ASP.NET session state supports several different storage options for session data. Each option is 
identified by a value in the SessionStateMode enumeration. 
The following list describes the available session state modes: 
* StateServer mode, which stores session state in a separate process called the ASP.NET state service. 
This ensures that session state is preserved if the Web application is restarted and also makes session 
state available to multiple Web servers in a Web farm. 
* SQLServer mode stores session state in a SQL Server database. This ensures that session state is 
preserved if the Web application is restarted and also makes session state available to multiple Web 
servers in a Web farm. 
* InProc mode, which stores session state in memory on the Web server. This is the default. 
* Custom mode, which enables you to specify a custom storage provider. 
* Off mode, which disables session state.

41. Topic 3, Video Transcoding Service 
 
Background 
The safer , easier way to help you pass any IT exams. 
50 / 76 
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.

Answer: A 
Explanation: 
In case you don’t want to use the RDP certificate created by Windows Azure Tools and want to use a 
custom certificate instead, the following steps will guide you. These steps can also be used in case 
package is not being published from Visual Studio rather it is being built locally, saved in either Local 
Machine's Drive or Windows Azure Blob Storage and subsequently published from there. 
Here are the steps which are required to get pass the publishing error which you might be running into.

You would need to upload the Certificate with Private Key to the portal (when Visual Studio is used this is 
done in the background). 
Detailed steps. 
1. In Visual Studio, go to the solution which is being developed. 
2. Right click the Web Project -> Configure Remote Desktop -> click on View to see Certificate details 
(Since I don’t have a custom certificate I will use one create by Windows Azure Tools itself) 
3. Go to Details tab on Certificate -> Click Copy to file.. -> Next -> Select ‘Yes, export the private key’ -> 
Next -> Continue with default setting and create a password when asked (please refer below 
screenshots) 
4. These steps will generate a .PFX file for this certificate. Now we need to upload this certificate to the 
portal (for the respective cloud service) 
5. Go to the Azure Management Portal -> Go to the Cloud Service in question -> Certificates Tab -> 
Upload the newly created certificate (.PFX file) 
Note: 
* The certificates that you need for a remote desktop connection are different from the certificates that you 
use for other Azure operations. The remote access certificate must have a private key. 
* Microsoft Azure uses certificates in three ways: 
/ Management certificates – Stored at the subscription level, these certificates are used to enable the use 
of the SDK tools, the Windows Azure Tools for Microsoft Visual Studio, or the Service Management REST 
API Reference. These certificates are independent of any cloud service or deployment. 
/ Service certificates – Stored at the cloud service level, these certificates are used by your deployed 
services. 
/ SSH Keys – Stored on the Linux virtual machine, SSH keys are used to authenticate remote connections 
to the virtual machine.

more, the controller is secure, otherwise an exception is thrown. 
From scenario: 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.

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.
