Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation Sample Questions:
1. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You set the logKnownPii attribute to true for the only trace source in the app.config file. You discover that the personal identifiable information (PII) is not logged.
You need to ensure that the PII is logged.
What should you do?
A) Set the logKnownPii attribute to true in the web.config file.
B) Disable encryption of the AppSettings element in the web.config file.
C) Set the enableLoggingKnownPii attribute to true in the machine.config file.
D) Set the enableLoggingKnownPii attribute to true in the app.config file.
2. You are creating a client application by using Microsoft .NET Framework 3.5. The client application uses a Windows Communication Foundation service. To log the called service proxy methods and their parameters, you implement custom endpoint behavior in the following class.
class ParametersLoggerBehavior: lEndpointBehavior
{}
You also create the following class for the custom behavior.
class LoggerElement
: BehaviorExtensionElement {}
You add the following configuration code fragment to the application configuration file.
(Line numbers are included for reference only.)
You need to ensure that the endpoint uses the custom behavior. Which configuration settings should you insert at line 03?
A) <behavior name="debug"> <debugBehavior /> </behavior>
B) <debugBehavior name="debug" />
C) <behavior name="debug"> <ParametersLoggerBehavior /> </behavior>
D) <ParametersLoggerBehavior name="debug"> <debugBehavior /> </ParametersLoggerBehavior>
3. You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service contains the following code segment.
You need to ensure that the service instance is recycled when the transaction is complete. Which line of code should you insert at line 06?
A) Option A
B) Option C
C) Option D
D) Option B
4. You create a Windows Communication Foundation (WCF) application by using Microsoft .NET Framework 3.5. The desktop client calls the WCF service to query its status. The call can take up to 10 seconds to complete.
The client application must remain responsive when querying the service. You need to generate the required proxy.
What should you do?
A) Execute the svcutil /validate /serviceName:MyWCF myServiceHost.exe command.
B) Execute the svcutil myServiceHost.exe /serviceName:MyWCF command.
C) Clear the Generate asynchronous operation check box in the Add Service Reference Settings dialog box.
D) Execute the svcutil http: //localhost:8000/MyWCF /async command.
5. You are creating a remote database management application by using Microsoft Windows Forms and Microsoft .NET Framework 3.5. You use the Windows
Communication Foundation model to create the application. You write the following code segment. (Line numbers are included for reference only.)
01 public class QueryAnalyzerService :
02 IQueryAnalyzerService, IDisposable {
04 public void Open() {
05}
06 public void ExecuteSql(string sql) {
07...
08!
09 public void Close() {
10...
11}
12 public void Disposed
13...
14}
15...
16}
You need to ensure that each time a client application calls the Open0 method, a new service instance is created. Which code segment should you insert at line 03?
A) [OperationBehavior( AutoDisposeParameters=true)]
B) [OperationBehavior( TransactionScopeRequired=true)]
C) [OperationBehavior( ReleaselnstanceMode=ReleaselnstanceMode.BeforeCall))
D) [OperationBehavior( ReleaselnstanceMode=ReleaselnstanceMode.None)]
