Bhttp://localhost:54946/DirectoryService.svc/Students?$filter=FirstName eq 'John'/Grades

Chttp://localhost:54946/DirectoryService.svc/Students?$filter=FirstName = 'John' &$expand=Grades

Dhttp://localhost:54946/DirectoryService.svc/Grades/Students?$filter=FirstName eq 'John'

Answer : A

Question 6

You are developing a WCF service.

You need to create a duplex contract.

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

AApply the MessageContractAttribute attribute to every public method signature included in the appropriate contract.

BCreate an interface for the client-side duplex contract.

CCreate an interface for the server-side duplex contract.

DApply the MessageContractAttribute attribute to the appropriate interface.

EApply the ServiceContractAttribute attribute to the appropriate interface. Then, apply the OperationContractAttribute attribute to every public method signature included in that contract.

FSet the CallbackContract property to the appropriate interface.

Answer : C, E, F

To create a duplex contract

(E) Apply the ServiceContractAttribute class to the interface.

Declare the method signatures in the interface.

(E) Apply theOperationContractAttributeclass to each method signature that must be part of the public contract.

Create the callback interface that defines the set of operations that the service can invoke on the client.

Declare the method signatures in the callback interface.

Apply theOperationContractAttributeclass to each method signature that must be part of the public contract.

(F) Link the two interfaces into a duplex contract by setting theCallbackContractproperty in the primary interface to the type of the callback interface.

Question 7

You are deploying an ASP.NET Core API application to an Azure App Services Docker container instance.
