Q33. - (Topic 4) 

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

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. Add the following code to the web.config file of the application. 

<customErrors mode=”On” > 

<error statusCode=”404” redirect=”CustomErrors.html” /> 

</customErrors> 

B. From the Debug menu in Visual Studio, select Exceptions. Disable the User-unhandled 

check box for Common Language Runtime Exceptions. 

C. Add the following code to the web.config file of the application. 

<customErrors mode=“On” > 

<error statusCode=”500” redirect=”CustomErrors.html” /> 

</customErrors> 

D. From the Debug menu in Visual Studio, select Exceptions. Enable the Thrown check 

box for Common Language Runtime Exceptions. 

Answer: D 

Explanation: 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.

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.
