You use Visual Studio .NET to develop applications for your human resources department. You
create the following interfaces:
Public Interface IEmployee
Property Salary() As Double
End Interface
Public Interface IExecutive
Inherits IEmployee
Property AnnualBonus() As Double
End Interface
The IEmployee interface represents a generic Employee concept. All actual employees in your
company should be represented by interfaces that are derived from IEmployee.
Now you need to create a class named Managed to represent executives in your company. You
want to create this class by using the minimum amount of code. You write the following code:
Public Class Manager
End class
Which additional code segment or segments should you include in Manager? (Choose all that
apply)

You develop an application that enables users to enter and edit purchase order details. The
application includes a Windows Form named DisplayXYZForm. The application uses a client-side
DataSet object to manage data.
The DataSet object contains a Data Table object named XYZDetails. This object includes one
column named Quantity and another named UnitPrice. For each item on a purchase order, your
application must display a line item total in a DataGrid control on DisplayXYZForm. The line item
is the product of Quantity times UnitPrice. Your database design does not allow you to store
calculated values in the database.
You need to add code to your Form_Load procedure to calculate and display the line item total.
Which code segment should you use?
A. Dim totalColumn As New DataColumn("Total", _ Type.GetType("System.Decimal"))
XYZDetails.Columns.Add(totalColumn)
totalColumn.Expression = "Quantity * UnitPrice"
B. Dim totalColumn As New DataColumn("Total", _ Type.GetType("System.Decimal"))
XYZDetails.Columns.Add(totalColumn)
totalColumn.Equals("Quantity * UnitPrice")
C. XYZDetails.DisplayExpression("Quantity * UnitPrice")
D. XYZDetails.DisplayExpression("quantityColumn + _ unitPriceColumn")

You use Visual Studio .NET to develop a Windows-based application that will manager vendor
contracts.
You create a DataSet object, along with its associated DataTable object and DataView object.
The DataSet object contains all data available for a single contract. This data is displayed in a
DataGrid control. After all parties sign a contract, the value in a field named ContractEXApproved
is set to True.
Business rules prohibit changes to database information about a contract when the
ContractEXApproved value associated with the contract is true.
You must ensure that this business rule is enforces by your application code.
What should you do?
A. Set the AllowNew property of the DataSet object to False.
B. Set the AllowEdit property of the DataView object to False.
C. Call the EndEdit method of the DataTable object.
D. Call the EndEdit method of the DataRow object.

You create an assembly by using Visual Studio .NET. The assembly is consumed by other .NET
applications to manage the creation and deletion of XML data files.
The assembly includes a method named DeleteXYZXMLFile that uses the Win32 API to delete
the XML data files. A security exception is thrown when DeleteXYZXMLFile is called from another
.NET application.
You must modify DeleteXMLFile to ensure that this method can execute functions exposed by the
Win32 API. To do so, you create a SecurityPermission object that represents the right to call
unmanaged code.
Which method of the SecurityPermission object should you call?

B. Demand
C. PermitOnly
D. RevertDeny

You use Visual Studio .NET to create a Windows-based application. The application includes a
form named ConfigurationForm.
ConfigurationForm contains 15 controls that enable users to set basic configuration options for
the application. You design these controls to dynamically adjust when users resize
ConfigurationForm. The controls automatically update their size and position on the form as the
form is resized. The initial size of the form should be 650 x 700 pixels.
If ConfigurationForm is resized to be smaller then 500 x 600 pixels, the controls will not be
displayed correctly. You must ensure that users cannot resize ConfigurationForm to be smaller
than 500 x 600 pixels.
Which two actions should you take to configure ConfigurationForm? (Each correct answer
presents part of the solution. Choose two.)
A. Set the MinimumSize property to 500,600.
B. Set the MinimumSize property to 650,700.
C. Set the MinimizeBox property to True.
D. Set the MaximumSize property to 500,600.
E. Set the MaximumSize property to 650,700.
F. Set the MaximizeBox property to True.
G. Set the Size property to 500,600.

You develop a Windows-based application for your payroll department. The application will
include a procedure named Signin, which must allow users to report that they are present in their
offices. The procedure must also allow each user to sign in other users. The procedure must

out of scope. Add code after each instance to manually invoke the Visual Studio .NET garbage
collector.
