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. Insert the following code segment at line 07. using (SqlConnection conn = new SqlConnection(connString)){
  conn.Open();
  }
• B. 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();
  }
• 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. 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();
  }

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application connects to several SQL Server databases. You create a function that modifies customer records that are stored in multiple databases. All updates for a given record are performed in a single transaction. You need to ensure that all transactions can be recovered. What should you do?

• A. Call the RecoveryComplete method of the TransactionManager class.
• B. Call the EnlistVolatile method of the Transaction class.
• C. Call the Reenlist method of the TransactionManager class.
• D. Call the EnlistDurable method of the Transaction class.

You are implementing an ASP.NET MVC 2 Web application. A controller contains the following code.
public ActionResult Edit(int id)
{
return View(SelectUserToEdit(id));
} public ActionResult Edit(Person person) { UpdateUser(person); return RedirectToAction("Index"); } The first Edit action displays the user whose details are to be edited, and the second Edit action is called when the Save button on the editing form is clicked to update the user details. An exception is thrown at run time stating that the request for action Edit is ambiguous. You need to correct this error and ensure that the controller functions as expected. What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

• A. Add the following attribute to the second Edit action. [HttpPut]
• B. Add the following attribute to the first Edit action. [HttpGet]
• C. Add the following attribute to the first Edit action. [AcceptVerbs(HttpVerbs.Head)]
• D. Add the following attribute to the second Edit action. [HttpPost]

You are creating an ASP.NET Web site. The site contains pages that are available to anonymous users.
The site also contains a page named Premium.aspx that provides premium content to only members of a
group named Subscribers.
You need to modify the web.config file to ensure that Premium.aspx can be accessed by only members of
the Subscribers group.
Which configuration should you use?

• A. <location path="Premium.aspx"> <system.web> <authorization> <deny users="*"/> <allow roles="Subscribers"/>
  </authorization>
  </system.web>
  </location>
• B. <location path="Premium.aspx"> <system.web> <authorization> <allow users="Subscribers"/> <deny users="*"/> </authorization> </system.web> </location>
• C. <location path="Premium.aspx"> <system.web> <authorization> <allow roles="Subscribers"/> <deny users="?"/> </authorization> </system.web> </location>
• D. <location path="Premium.aspx"> <system.web> <authorization> <allow roles="Subscribers"/> <deny users="*"/> </authorization> </system.web> </location>
