You are developing an ASP.NET MVC application in a web farm. The application has a page that accepts a customer’s order, processes it, and then redirects the browser to a page where the order is displayed along with the shipping information.
The order information should be available only to the page where the order is displayed.
You need to store state and configure the application.
What should you do? To answer, drag the appropriate item to the correct location. Each item 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.

Q62. - (Topic 4)
You are designing an enterprise-level Windows Communication Foundation (WCF) application. User accounts will migrate from the existing system. The new system must be able to scale to accommodate the increasing load.
You need to ensure that the application can handle large-scale role changes.
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
Answer: B,C
Explanation: Advanced Maturity: Authorization as a Service In the advanced level of maturity for authorization, role storage and management is consolidated and authorization 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 of assuming the identity of the user, the application uses its own credentials to access services and resources, but it captures the user's identity and passes it as a parameter (or token) to be used for authorization when a request is made. This model is referred to as the trusted subsystem model, because the application acts as a trusted subsystem within the security domain.
Q63. - (Topic 4)
You are designing an enterprise-level Windows Communication Foundation (WCF) application. User accounts will migrate from the existing system. The new system must be able to scale to accommodate the increasing load.
The new servers are experiencing significant stress under load of large-scale role changes.
You need to ensure that the application can handle the stress.
Which authorizations should you redesign? (Each correct answer presents a complete solution. Choose all that apply.)
A. Role-based approach
B. Identity-based approach
C. Resource-based trusted subsystem model
D. Resource-based impersonation/delegation model

Q68. DRAG DROP - (Topic 4)
You are developing an ASP.NET MVC application in Visual Studio 2012. The application will be viewed with browsers on desktop devices and mobile devices. The application uses the Razor View Engine to display data.
The application contains two layouts located in the /Views/Shared directory.
These layouts are named:
. _Layout.cshmtl
. _MobleLayoutcshtml
The application must detect if the user is browsing from a mobile device. If the user is browsing from a mobile device, the application must use the _MobileLayout.cshtml file. If the user is browsing from a desktop device, the application must use .Layout, cs html.
You need to ensure that the application renders the layout that is appropriate for the browser.
You have the following code:
Which code segments should you include in Target 1, Target 2 and Target 3 to complete the code of the ViewStart.cshtml file? (To answer, drag the appropriate code segments to the correct targets.

Q70. - (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
