Q23. - (Topic 4) 

You are authoring unit tests.

You need to create, maintain, and inject dependencies in the unit tests. 

Which isolation method should you use? 

A. T4 text templates and code generation 

B. Stub types 

C. Shim types 

D. Hard-coded implementation 

Answer: C 

Explanation: http://msdn.microsoft.com/en-us/library/hh549176.aspx 

Shim types are one of two technologies that the Microsoft Fakes Framework uses to let you easily isolate components under test from the environment. Shims divert calls to specific methods to code that you write as part of your test. Many methods return different results dependent on external conditions, but a shim is under the control of your test and can return consistent results at every call. This makes your tests much easier to write.

Q27. - (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 

Q28. DRAG DROP - (Topic 4) 

You are developing an ASP.NET MVC application in Visual Studio 2012. The application contains sensitive bank account data. 

The application contains a helper class named SensitiveData.Helpers.CustomEncryptor. 

The application must not display AccountNumber in clear text in any URL. 

You need to build the view for the GetAccounts action. 

How should you build the view? (To answer, drag the appropriate code segment to the correct location or locations. Each code segment 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.) 

Answer: 

Q29. - (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. 

Q30. DRAG DROP - (Topic 4)

The application must: 

. Use Windows Identity Foundation 4.5.

You need to implement authentication. 

How should you build the class constructor? (To answer, drag the appropriate code segment to the correct location or locations in the answer area. Each code segment 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.)
