1. You create Web-based client applications. You are creating a class library that will be used by an e-commerce 
Web-based application. The library has an abstract class that is named Product. The Product class serves as a base 
class for the other classes and provides a default ProductID property.
Each class other than the base class represents a type of product that is sold by your company. There is a ProductID 
property and a GetProductDetails procedure for each product type.
You need to ensure that the application meets the following requirements:
What should you include in the Product class?
A. a MustOverride ProductID property and an overridable GetProductDetails procedure
B. an overridable ProductID property and an overridable GetProductDetails procedure
C. an overridable ProductID property and a MustOverride GetProductDetails procedure
D. a MustOverride ProductID property and a MustOverride GetProductDetails procedure
Answer: C
2. You create Web-based client applications. You are creating an application that must access different databases 
depending on whether the application is in demonstration, production, or test mode. The mode is stored in an 
environment variable.
The configuration file contains the following settings.
You need to ensure that changing the mode will not require you to change the configuration file.
Which code segment should you use?
A. Public Function GetConnectionString() As String
#If PROD Then
Return WebConfigurationManager. _
ConnectionStrings("ProdDB").ConnectionString
#ElseIf DEMO Then
Return WebConfigurationManager. _
ConnectionStrings("DemoDB").ConnectionString
#Else
Return WebConfigurationManager. _
?ConnectionStrings("TestDB").ConnectionString
#End If
End Function
 
 

 
 
B. Public Function GetConnectionStringB() As String
Return WebConfigurationManager.ConnectionStrings( _
Environment.GetEnvironmentVariable("WebAppModeDB")) _
.ConnectionString()
End Function
C. Public Function GetConnectionString() As String
Return ConfigurationSettings.AppSettings( _
Environment.GetEnvironmentVariable("WebAppModeDB"))
End Function
D. Public Function GetConnectionString() As String
#If PROD Then
Return ConfigurationSettings.AppSettings("ProdDB")
#ElseIf DEMO Then
Return ConfigurationSettings.AppSettings("DemoDB")
#Else
Return ConfigurationSettings.AppSettings("TestDB")
#End If
End Function
E. Public Function GetConnectionString() As String

3. You create Web-based applications. You are creating an Internet banking application. 
You write the following lines of code to represent a method in your application. (Line numbers are included for 
reference only.)
You use the Microsoft Visual Studio 2005 test feature to automatically generate the following unit test. (Line numbers 
are included for reference only.)
You need to change the test method to return a conclusive result.
Which line of code should replace the code on line 07 of the unit test?
A. Assert.AreEqual(400D, target.Balance)
B. Assert.IsTrue(target.Balance <> 400D)
C. Debug.Assert(target.Balance = 400D, "passed")
D. Debug.Assert(target.Balance = 400D, "failed")
Answer: A
4. You create Web-based client applications. You are designing a new Web site for your company. You need to 
evaluate the design concept for the main page, default.aspx.
The default.aspx page contains static information, except for one data grid that displays information about the 
company's products. The data grid will retrieve the data from a component. The component will retrieve the data from a 
stored procedure. The page has the appropriate permissions to the Microsoft SQL Server database.
The application design must achieve the following goals without altering the data component:
You decide to use a sqlCacheDependency attribute to ensure that the default.aspx page always displays the latest 
data in the grid.
You need to ascertain whether the use of the sqlCacheDependency attribute meets the requirements of this 
application.
Which rationale should you choose?
A. The use of the sqlCacheDependency attribute is not feasible. The sqlCacheDependency attribute must be used in 
the component and not on the page.
B. The use of the sqlCacheDependency attribute is not feasible. The sqlCacheDependency attribute cannot be used 
with a stored procedure.
C. The use of the sqlCacheDependency attribute is feasible. The sqlCacheDependency attribute can be used by 
including a sqlDependency attribute in the @OutputCache directive of the page.
 
 
 

 
 
D. The use of the sqlCacheDependency attribute is feasible. The sqlCacheDependency attribute can be linked to the 
data component that is used on the page.
Answer: C
5. You create Web-based client applications. You are designing an extranet site for a company of trading partners. 
You decide to use the following technologies:
Before implementation, these technologies must be validated. You propose the following approach to perform the 
validation:
You need to evaluate whether the approach validates the proposed technology successfully.
What should you conclude?
A. The approach validates the use of the proposed technology for the application.
B. The approach does not validate the use of the proposed technology for the application. The company and the 
partner need to create test applications. The test applications need to read data in the proposed XML schema to 
establish the validation.
C. The approach does not validate the use of the proposed technology for the application. The company and the 
partner need to coordinate their Active Directory tree into a shared Active Directory forest.
D. The approach does not validate the use of the proposed technology for the application. You must either use an 
existing publicly documented XML schema or register the shared XML schema by using an authentication site.
Answer: B
6. You create Web-based client applications. You create a component named Orders for a company named 
Northwind Traders.
This component is used to retrieve and update data in the Orders table of the company's database. The schema of the 
Orders table is as shown in the following Exhibit. (Click the Exhibit button.)
The Orders component permits the client application to perform the following tasks:
An instance of the Order class represents a single order that is identified by the OrderID parameter. An instance of 
the Order class permits the client application to perform the following tasks:
You need to create the design for the component.
What should you do?
To answer, drag the appropriate members to the correct locations in the member type column.
Answer:
7. You create Web-based client applications. You are reviewing a Web application page that populates a list of all 
employees of your company.
You analyze code and find that the Web application page does not prevent exceptions from traveling to the browser.
You need to ensure that the Web application page intercepts exceptions and presents an error message to the 
browser.
What change should you suggest?
A. Add the following code segment to the Web.config file.
<system.web>
<compilation debug="true"/>
</system.web>
B. Add the following code segment to the page.
Protected Sub Page_Error(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles Me.Error
Response.Redirect("error.aspx")
End Sub
C. Add the following code segment to the Web.config file.
<system.web>
<customErrors mode="Off"/>
</system.web>
D. Change the Load event handler to the following code segment.
Protected Sub Page_Load(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles Me.Load
 
 
 

 
 
Try
LoadEmployees()
Catch
Response.Redirect("error.aspx")
End Try
End Sub
Answer: B
8. You create components for Web-based client applications. You are creating a BankAccount class. 
The BankAccount class contains an AccountNumber property and a CreateAccount method. The CreateAccount 
method is used to create a new account. The method generates a unique random value for the actNumber field.
You need to ensure that the BankAccount class is extendable, and that it serves as the base class for other derived 
classes. You also need to ensure that each derived class can have its own guidelines to generate account numbers in 
the CreateAccount method.
Which code segment should you use?
A. Public Class BankAccount
Protected actNumber As Long
Public ReadOnly Property AccountNumber() As Long
Get
Return actNumber
End Get
End Property
Public Overridable Function CreateAccount() As BankAccount
...
End Function
End Class
B. Public Class BankAccount
Private actNumber As Long
Public ReadOnly Property AccountNumber() As Long
Get
Return actNumber
End Get
End Property
Public Overridable Function CreateAccount() As BankAccount
...
End Function
End Class
C. Public Class BankAccount
Protected actNumber As Long
Public ReadOnly Property AccountNumber() As Long
Get
Return actNumber
End Get
End Property
Public Function CreateAccount() As BankAccount
...
End Function
End Class

End Class
Answer: A
9. You create Web-based applications. You create a loan application form.
The loan application form is used to calculate the monthly payment of loans. The monthly payment is based on the 
loan amount, rate, and number of months. The form contains four text boxes and a button. There are no other controls 
in the form. The application event handler has the following lines of code. (Line numbers are included for reference 
only.)
You must prevent exceptions whenever possible to meet the application requirements.
You need to evaluate the current exception handling mechanism.
What should you conclude?
A. The current exception handling mechanism meets the requirements. Nothing needs to be changed.
B. The current exception handling mechanism does not meet the requirements. A required field validator and a range 
validator control must be added to validate each text box before the button is clicked.
C. The current exception handling mechanism does not meet the requirements. A required field validator control must 
be added to validate each text box before the button is clicked.
D. The current exception handling mechanism does not meet the requirements. A regular expression validator control 
must be added to validate each text box before the button is clicked.
Answer: B
10. You create Web-based client applications. You are creating a class named Product. The Product class will be 
used by a Web-based application to retrieve and modify product information.
When you create an instance of the Product class, you retrieve the current information from the Products table. The 
Product class contains a static member named CreateNewProduct. The CreateNewProduct method is used to add a 
new product to the database and return the primary key. The Products table contains the following fields:
You need to create the constructor for the Product class.
Which code segment should you use?
A. Public Sub New(ByVal ProductID As Integer, ByVal ProductName As String, ByVal Description As String, ByVal 
CategoryID As Integer, ByVal CurrentPrice As Decimal)
 
'Insert code here 
 End Sub 
B. Public Sub New(ByVal ProductID As Integer, ByVal ProductName As String)
'Insert code here
End Sub
C. Public Sub New()
'Insert code here
End Sub
D. Public Sub New(ByVal ProductID As Integer)
'Insert code here
End Sub
Answer: D

according to one of the following rules:
You are translating the specification given here into pseudo code. You start by writing the following code.
You need to insert the correct pseudo code.
Which code segment should you insert?
A. If amount < balance then balance - = amount 
 
    
 
 
 
   
 
 

 
 
   
 
 
If amount < balance + 500 then balance = balance - (amount + 35) 
If amount > balance + 500 then throw exception
B. If amount <= balance then balance - = amount 
If amount <= balance + 500 then balance = balance - (amount + 35) 
If amount > balance + 500 then throw exception
C. If amount < balance then balance - = amount 
Else If amount < balance + 500 then balance = balance - (amount + 35) 
Else throw exception
D. If amount <= balance then balance - = amount 
Else If amount <= balance + 500 then balance = balance - (amount + 35) 
Else throw exception
Answer: D
12. You create Web-based client applications. 
You are evaluating the design of an e-commerce Web site. The Web site processes credit card information. The Web 
site has a shopping cart and expects a high volume of traffic, especially during peak shopping times.
The design specifications for the application must meet the following criteria:
You need to evaluate the design of the application and recommend whether it is technically feasible and complete.
What should you conclude?
A. The design is technically feasible, but it is not complete. The application must be configured to use cookieless 
sessions. Each server on the farm must use a unique certificate.
B. The design is technically feasible and complete.
C. The design is technically feasible, but it is not complete. The servers must have their affinity set to a single host 
(sticky sessions).
D. The design is not technically feasible. The application cannot be hosted on a Web farm.
Answer: C
13. You create Web-based client applications. You are reviewing a Web application page that populates the list of all 
employees for your company.
The following code segment loads the list of employees from a database.
You analyze the code segment. You find that the database connection fails to close properly when the GetEmployees 
method throws an exception.
You need to recommend a change in the code segment to ensure that every possible code path closes the database 
connection.
Which code segment should you recommend?
A. ' Create the connection and open it
Using conn As DbConnection = factory.CreateConnection()
