Microsoft Exam 70-486 MCSA: Web Applications Certification Dumps

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 ViewsShared_Layout.cshtml.

Models:

The application uses the ModelsLogModel.cs model.

Views:

All views in the application use the Razor view engine.

Four views located in ViewsRunLog are named:

- _CalculatePace.cshtml

- EditLog.cshtml

- GetLog.cshtml

- InsertLog.cshtml

The application also contains a ViewsHomeIndex.cshtml view.

Controllers:

The application contains a ControllersRunLogController.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.

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.)

41. 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

You need to ensure that developers can connect to a Windows Azure role by using RDP.
