QUESTION 75
You need to add a method to the ProductController class to meet the exception handling requirements for logging. Which code segment should you use?
A. Option A
B. Option B
C. Option C

Answer: A
QUESTION 76
You 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.
Answer: AD
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:
– without [DataContract], you cannot define an XML namespace for your data to live in
– without [DataMember], you cannot serialize non-public properties or fields
– without [DataMember], you cannot define 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 by the DCS

Case Study 3 – Video Transcoding Service (QUESTION 87 – QUESTION 97)
For help on how to answer the questions, click the Instuctions button on the question screen.
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
TranscodeWorkerRole.cs
ThumbnailGenerator.cs
VideoController.cs
DeleteHandler.cs
VideoAdminAttributes.cs
AdminVerifierFactory.cs
ImageConverter.cs
QUESTION 87
You need to secure the administrative functions for all MVC controllers. Which code segment should you use as the body for the CreateController method in AdminVerfierFactory.cs?
Answer: D
Explanation:
The MemberInfo.CustomAttributes property gets a collection that contains this member’s custom attributes. The Any() statement will either return null or a collection of matched custom attributes. If it matches one or 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.
Incorrect:
Not B: controller.GetType().Attributes will not return custom attributes.

QUESTION 88
Customers download videos by using HTTP clients that support various content encodings. You need to configure caching on the DownloadVideo action to maximize performance. Which attribute should you add?
A. Option A
B. Option B
C. Option C
D. Option D

Answer: E
QUESTION 89
You need to ensure that all the MVC controllers are secure. Which code segment should you use as the body for the CreateController method in AdminVerifierFactory.es?

QUESTION 90
You are creating a new authentication system that uses an HTTP header value. The existing authentication system must continue to operate normally. You need to implement the custom authentication. What should you do? (Each correct answer presents a complete solution. Choose all that apply.)
A. Create a class derived from ActionResult and check for a valid HTTP header value in the ExecuteResult method.

D. Create a class derived from AuthorizeAttribute and check for a valid HTTP header value in the AuthorizeCore method.
Change usages of the existing AuthorizeAttribute to use the new class.
