Olympic Marathon

BackgroundYou are developing an ASP.NET MVC application in Visual Studio 2012 that will be used by Olympic marathonrunners 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.cshtmlEditLog.cshtmlGetLog.cshtmlInsertLog.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 Flashapplication and video. The browser should display the video natively if possible, using H264, Ogg, or WebMformats, 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.es contains a custom role provider.

Relevant portions of the application files follow. (Line numbers are included for reference only.)

QUESTION 2You are designing a Windows Communication Foundation (WCF) service that uses the Product class.You need to update the class to meet the storage requirement.

What should you do? (Each correct answer presents part of the solution. Choose all that apply.)

A. Mark the Product class with the DataContract attribute.

B. Mark the public members of the Product class with the DataContractFormat attribute.

C. Mark the Product class with the CollectionDataContract attribute.

D. Mark the public members of the Product class with the DataMember attribute.


Explanation/Reference:So as of .NET 3.5 SP1, you don't have to add data contract or data member attributes anymore - if you don'tthen the data contract serializer will serialize all public properties on your class, just like the XML serializerwould.HOWEVER: by not adding those attributes, you lose a lot of useful capabilities:without [DataContract], you cannot define an XML namespace for your data to live inwithout [DataMember], you cannot serialize non-public properties or fields without [DataMember], you cannotdefine an order of serialization (Order=) and the DCS will serialize all properties alphabetically without[DataMember], you cannot define a different name for your property (Name=)without [DataMember], you cannot define things like IsRequired= or other useful attributes

without [DataMember], you cannot leave out certain public properties - all public properties will be serialized bythe DCS

Testlet 1

Video Transcoding Service

BackgroundYou 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 theworld.

Business Requirements

The user-facing portion of the application is an ASP.NET MVC application. It provides an interface foradministrators to upload video and schedule transcoding. It also enables administrators and users to downloadthe transcoded videos.

When videos are uploaded, they are populated with metadata used to identify the video. The video metadata isgathered 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. Thisinformation is read from a cookie that is set on the server. The administrative links must not be present if anerror condition is present.


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 isinstalled, 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 beunregistered when it is not in use.The transcoding utility requires a significant amount of resources. A maximum of 10 instances of the utility canbe running at any one time. If an instance of the role cannot process an additional video, it must not prevent anyother 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.exeutility.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.


QUESTION 1The transcode.exe utility activates its license online when it is installed. You need to ensure that the registrationof the transcode utility is handled as specified in its license.

Which method should you add to the TranscodeWorkerRole class?

A. Option A

B. Option B

C. Option C

D. Include language-specific content in the assembly manifest and use .NET culture libraries.


Explanation/Reference:A resource file is an XML file that contains the strings that you want to translate into different languages orpaths to images. The resource file contains key/value pairs. Each pair is an individual resource. Key names arenot case sensitive. For example, a resource file might contain a resource with the key Button1 and the valueSubmit. You create a separate resource file for each language (for example, English and French) or for alanguage and culture (for example English [U.K.], English [U.S.]). Each localized resource file has the samekey/value pairs; the only difference is that a localized resource file can contain fewer resources than the defaultresource file. The built-in language fallback process then handles loading the neutral or default resource.

Session States in Windows Azure.If you are a Web developer, you are probably very familiar with managing user state - that is you are familiarwith tracking user activity and actions across several request-response exchanges that occur in Webapplications. Since HTTP is a stateless protocol, developers over the years have developed all sorts of meansto manage state. You'll even find an MSDN page providing alternatives and recommendations for statemanagement 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.

Correct Answer: CDESection: [none]Explanation

Explanation/Reference:The SemanticZoom control enables the user to switch between two different views of the same content. One ofthese is the main view of the content. The second view is a view of the same content represented in a way thatallows users to quickly navigate through it. For example, when viewing an address book, the user could zoom inon a letter and see the names associated with that letter.To provide this zooming functionality, the SemanticZoom control uses two other controls: one to provide thezoomed-in view and one to provide the zoomed-out view.

* From scenario:The app must include a photo viewer. When photos are added or deleted in the photo viewer window, theymust animate in and out of the field of view. Remaining photos must move to fill the empty space created whenphotos are deleted. The photo viewer must support semantic zoom.

E. Confirm that the IsCancellationRequested property of the CancellationToken object is true and exit the task.

F. Update the DoWork() method to receive a CancellationToken object in the arguments of the method.

Correct Answer: DEFSection: [none]Explanation

Explanation/Reference:Cancellation is controlled by the CancellationToken structure. You expose cancellation tokens in the signatureof cancelable async methods, enabling them to be shared between the task and caller. In the most commoncase, cancellation follows this flow:1. (D) The caller creates a CancellationTokenSource object.2. (F) The caller calls a cancelable async API, and passes the CancellationToken from theCancellationTokenSource (CancellationTokenSource.Token).3. The caller requests cancellation using the CancellationTokenSource object(CancellationTokenSource.Cancel()).4. (E)The task acknowledges the cancellation and cancels itself, typically using theCancellationToken.ThrowIfCancellationRequested method.

* From scenario:/ The SocialPoller background task must run the code in the DoWork() method to collect content from theContoso feed./ The UI must always remain responsive to user actions.

Note:* Task-based Asynchronous Pattern* CancellationToken Structure/ Propagates notification that operations should be canceled./ CancellationToken. IsCancellationRequestedGets whether cancellation has been requested for this token.

Topic 4, Fabrikam, Inc

OverviewFabrikam, Inc. is a realtor in the United States.

Fabrikam grants its customers access to a web site, where they can search for houses for rent and for sale. Itscustomers can enter basic requirements, such as location, number of rooms, dimensions, and a price range.The web site displays a list of houses that meet the customers' criteria. The customers can then view moredetails about each house and can add a listing to a favorites list.

Requirements

Business GoalsFabrikam plans to provide a more interactive experience for its customers. Fabrikam is creating a video tour foreach listing. The video tours can be used to visit the property virtually. Fabrikam plans to create a WindowsStore app on Windows 8.1 RT and Windows 8.1 Pro devices.

General RequirementsFabrikam identifies the following general requirements for the app:The app interface must be available in English, Spanish, and French. The app must provide the customers withthe ability to perform searches the same way that the current web site does.It is expected that the customers will view more than 3,000 pictures annually. The main page of the app must

show a list of the last 10 pictures that were viewed. If pictures are added to a listing that is in a customer'sfavorites list, the pictures must be downloaded automatically from Windows Azure. This must occur if the app issuspended or not running.

Printing RequirementsCustomers must be able to print the details of a listing from the details page by clicking a button within the app.

You plan to add the following XAML markup to the listing details page:

<Button x:Name="btnPrint Content="Print" Click="InvokePrint" />.

Video Tour RequirementsFabrikam identifies the following requirements for the video tours:Customers must be able to play the video tour on a different device by using a button within the app.When a customer clicks the details of a listing, the app must start downloading the video tour in thebackground.When the app starts, the app must verify whether there are any pending downloads, and resume any pauseddownloads.The last five viewed video tours that are not on the customer's favorites list must be cached for subsequentviewing.Customers must be able to download all of the video tours for the properties that they added to their favoriteslist.The property details page must contain a MediaElement control that will be used to play the video tour of theproperty.When downloading the video tours, the app must remain responsive, and each download must be processedon a separate thread.

A. Check the input against patterns seen in the logs and other records.

B. Escape single quotes and apostrophes on all string-based input parameters.

C. Implement parameterization of all input strings.

D. Filter out prohibited words in the input submitted by the users.


Explanation/Reference:SQL Injection Prevention, Defense Option 1: Prepared Statements (Parameterized Queries) The use ofprepared statements (aka parameterized queries) is how all developers should first be taught how to writedatabase queries. They are simple to write, and easier to understand than dynamic queries. Parameterizedqueries force the developer to first define all the SQL code, and then pass in each parameter to the query later.This coding style allows the database to distinguish between code and data, regardless of what user input issupplied.

Prepared statements ensure that an attacker is not able to change the intent of a query, even if SQLcommands are inserted by an attacker.

What should you use for authorization? (Each correct answer presents a complete solution.Choose all that apply.)

A. Resource-based trusted subsystem model

B. Identity-based approach

C. Role-based approach

D. Resource-based impersonation/delegation model


Explanation/Reference:Advanced Maturity: Authorization as a ServiceIn the advanced level of maturity for authorization, role storage and management is consolidated andauthorization itself is a service available to any solution that is service-enabled.

* The Trusted Subsystems Model

Once authorization is available as an autonomous service, the need for impersonation is eliminated. Instead ofassuming the identity of the user, the application uses its own credentials to access services and resources, butit captures the user's identity and passes it as a parameter (or token) to be used for authorization when arequest is made. This model is referred to as the trusted subsystem model, because the application acts as atrusted subsystem within the security domain.
