You are creating a Windows Communication Foundation (WCF) service based on WSHttpBinding. New
audit requirements dictate that callers must be authenticated on every call to ensure that their credentials
have not been revoked.
You need to ensure that the service will not cache the security request token.
What should you do?

• A.In the message security configuration, change clientCredentialType from IssuedToken to UserName.
• B.At the end of every operation, call the SessionStateUtility.RaiseSessionEnd method.
• C.In the message security configuration, set establishSecurityContext to false.
• D.Apply a ServiceBehavior attribute to the service implementation class with the InstanceContextMode property set to Single.

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create a Windows Communication Foundation (WCF) Data Services service. The service connects to a Microsoft SQL Server 2008 database. The service is hosted by an Internet Information Services (IIS) 6.0 server. You need to ensure that applications authenticate against user information stored in the database before the application is allowed to use the service. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A.Configure IIS to require basic authentication.
• B.Configure IIS to require Windows authentication.
• C.Enable the WCF Authentication Service.
• D.Configure IIS to allow anonymous access.
• E.Modify the Data Services service to use a Microsoft ASP.NET membership provider.

You are implementing an ASP.NET application that makes extensive use of JavaScript libraries. Not all pages use all scripts, and some scripts depend on other scripts. When these libraries load sequentially, some of your pages load too slowly. You need to use the ASP.NET Ajax Library Script Loader to load these scripts in parallel. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A.In your site's master page, add a call to Sys.loader.registerScript to define each of the scripts that are used in the site.
• B.In your site's master page, add a call to Sys.loader.defineScripts to define each of the scripts that are used in the site.
• C.In each page that uses scripts, add a call to Sys.require for each script that is needed in that page.
• D.In each page that uses scripts, add a call to Sys.get for each script that is needed in that page.

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application.
The application contains the following code segment. (Line numbers are included for reference only.)
01 class DataAccessLayer
02 {
03 private static string connString;
04
05 ...
06 public static DataTable GetDataTable(string command){
07
08 ...
09 }
10 }
You need to define the connection life cycle of the DataAccessLayer class. You also need to ensure that
the application uses the minimum number of connections to the database.
What should you do?

• A.Replace line 01 with the following code segment. class DataAccessLayer : IDisposable Insert the following code segment to line 04. private SqlConnection conn = new SqlConnection(connString); public void Open(){
  conn.Open();
  }
  public void Dispose(){
  conn.Close();
  }
• B.Insert the following code segment at line 07. using (SqlConnection conn = new SqlConnection(connString)){
  conn.Open();
  }
• C.Insert the following code segment at line 04. private SqlConnection conn = new SqlConnection(connString); public void Open(){
  conn.Open();
  }
  public void Close(){
  conn.Close();
  }
• D.Insert the following code segment at line 04. private static SqlConnection conn = new SqlConnection(connString); public static void Open(){
  conn.Open();
  }
  public static void Close(){
  conn.Close();
  }

You deploy an ASP.NET application to an IIS server.
You need to log health-monitoring events with severity level of error to the Windows application event log.
What should you do?

• A.Set the Treat warnings as errors option to All in the project properties and recompile.
• B.Run the aspnet_regiis.exe command.
• C.Add the following rule to the <healthMonitoring/> section of the web.config file. <rules> <add name="Failures"
  eventName="Failure Audits"
  provider="EventLogProvider" />
  </rules>
• D.Add the following rule to the <healthMonitoring/> section of the web.config file. <rules> <add name="Errors" eventName="All Errors" provider="EventLogProvider" /> </rules>
