Q61. - (Topic 4)

You are developing an Azure worker role. You enable crash dump collection for the role.

When the role starts, an external application stops responding.

You need to download the crash dump to determine why the application stops responding.

From which two locations can you download the crash dump? Each correct answer presents a complete solution.

A. Azure Blob storage

B. the temp folder on the virtual machine that is running the role instance

C. Azure file storage

D. the DiagnosticStore local resource folder on the virtual machine that is running the role instance

Answer: A,D

Explanation: When you enable collection of crash dumps, the resulting data is written to the CrashDumps directory in the DiagnosticStore local resource that is automatically configured for your role. When crash dump data is transferred to persistent storage, it is stored to the wad-crash-dumps Blob container.

Q63. - (Topic 4)

You are implementing a website redesign of an existing website that provides historical weather condition maps.

The current layout resembles the graphic in the exhibit. (Click the Exhibit button.)

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-selector".

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: A

Q64. HOTSPOT - (Topic 4)

You are developing an ASP.NET MVC application that authenticates a user by using claims-based authentication.

The application must:

. Use Windows Identity Foundation 4.5.

. Support the Windows Azure Access Control Service.

You need to implement authentication.

How should you build the class constructor? (To answer, select the appropriate option from the drop-down list in the answer area.)

Q65. - (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.

</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.

Q66. - (Topic 2)

You need to implement client-side animations according to the business requirements.

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

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.

Application Structure

Q67. DRAG DROP - (Topic 1)

You need to implement the Views\RunLog\_CalculatePace.cshtml partial view from Views\Runlog \GetLog.cshtml to display the runner's average mile pace.

How should you implement the view? (To answer, drag the appropriate code segments to the correct location or locations. 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:

Q68. - (Topic 4)

You are developing an ASP.NET MVC application that provides instant messaging capabilities to customers.

You have the following requirements:

Answer: D

Q69. - (Topic 4)

A. Annotate HTML5 content elements with Accessible Rich Internet Application (ARIA) attributes.

B. Convert HTML5 forms to XForms.

C. Ensure that HTML5 content elements have valid and descriptive names.

Answer: A,D

Q70. - (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>

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>

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.
