Answer: 

Topic 2, Web Application 

Background 

You are developing an online shopping web application. 

Business Requirements 

A user is not required to provide an email address. If a user enters an email 

address, it must be verified to be a valid email address. 

Information about the first product on the product page must fade out over time to 

encourage the user to continue browsing the catalog. 

Administrators must be able to edit information about existing customers. 

Administrators also must be able to specify a default product on the product page. 

Technical Requirements 

General: 

The web store application is in a load-balanced web farm. The load balancer is not 

configured to use server affinity. 

The web store application is an ASP.NET MVC application written in Visual Studio 

2012. 

Products: 

The value of the productId property must always be greater than 0. 

The Products page for mobile devices must display to mobile users. The Products 

page for desktop devices must display to desktop users. 

Storage: 

The data must be stored in a serialized XML data format. 

Serialized objects must be schema-independent. 

Exception handling: 

Exceptions originating from IIS must display a page with support contact 

information. 

Some page links expire, and users who access these links encounter 404 errors. 

Exceptions must be logged by using the WriteLog method of the Utility class. 

Browser and device support: 

The application must support image format conversions from .bmp to .jpeg for 

mobile devices. 

The application must support image format conversions from .bmp to .png for 

desktop devices. 

Application Structure 

Q15. - (Topic 4) 

You are developing an ASP.NET MVC application that uses forms authentication to verify that the user is logged in. 

Authentication credentials must be encrypted and secure so no user identity is exposed. 

You need to ensure that user credentials are persisted after users log on. 

Where should you store the credentials? (Each correct answer presents a complete solution. Choose all that apply.) 

A. In Session on the server 

B. In a cookie stored in the browser 

C. In ViewData in the application 

D. In TempData on the server 

Answer: A,B

Q16. - (Topic 2) 

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: A,D 

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 

Q17. - (Topic 2) 

You need to implement the requirements for handling IIS errors. What should you do? 

A. Option A 

B. Option B 

C. Option C 

D. Option D

Q18. - (Topic 2) 

You need to update the routes to ensure that a product is always displayed on the product page. 

Which code segment should you use? 

A. Option A

Q19. - (Topic 4) 

You are developing an ASP.NET MVC application that will run on Azure. 

The application uses Event Tracing for Windows (ETW) for logging operations. 

You need to retrieve the ETW data for the application from a deployed Azure instance by using the Azure Diagnostics API. 

Which data source should you use? 

A. Azure Diagnostic infrastructure logs 

B. Windows event logs 

C. performance counters 

D. .NET EventSource 

Answer: D 

Explanation: Azure Diagnostics 1.2 and 1.3 are Azure extensions that enable you to 

collect diagnostic telemetry data from a worker role, web role, or virtual machine running in 

Azure. 

Diagnostics 1.2 and 1.3 enable the collection of ETW and .NET EventSource events. 

Example: 

EtwProviders> 

<EtwEventSourceProviderConfiguration provider="SampleEventSourceWriter" 

scheduledTransferPeriod="PT5M"> 

<Event id="1" eventDestination="EnumsTable"/> 

<Event id="2" eventDestination="MessageTable"/> 

<Event id="3" eventDestination="SetOtherTable"/> 

<Event id="4" eventDestination="HighFreqTable"/> 

<DefaultEvents eventDestination="DefaultTable" /> 

</EtwEventSourceProviderConfiguration> 

</EtwProviders>
