When the exam begins, you can choose the programming language in which the code segments will appear. The available code languages for this exam are:

• Microsoft Visual Basic 2005

• Microsoft Visual C# 2005

1: You create Web-based client applications. You are creating a sales management application. The application will be used to produce sales orders. Sales data, including orders and product information, is stored in a central Microsoft SQL Server 2005 database. The application uses Microsoft Windows Integrated security to access data. You test the application component that is used to retrieve sales order information from the database. The tests are successful. You check the code back into the source control so that the other testers can utilize the code. The testers notify you that the application fails to connect to the database in the test environment. You test the application again and the tests are successful. You need to recreate the bug environment to investigate and resolve the bug. Which three aspects of the testing environment should you take into account? (Each correct answer presents part of the solution. Choose three.)
A.Web server processor speed
B.Database security settings
C.Network bandwidth
D.Web server available memory
E.Network credentials used for testing
F.Impersonation settings
Correct Answers: B E F

3: 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 void Page_Error(object sender, EventArgs e) {
  Response.Redirect("error.aspx");
}
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 void Page_Load(object sender, EventArgs e) {
  try {
    LoadEmployees();
  }
  Catch {
    Response.Redirect("error.aspx");
  }
}
Correct Answers: B

4: You create Web-based client applications. You are creating a Web site that displays product information for your company.
The application must meet the following requirements:
Support at least 20 concurrent users.
Consume less than 40 percent of the CPU time during peak usage.
Process at least five requests per second during peak usage, which is estimated to be between 20 and 30 users.
A Web test is created to verify the requirements by recording how a regular user would interact with the site. Then, based on the Web test, a load test is created. The load test simulates 30 users who execute the Web test simultaneously. You need to decide whether the current strategy is enough to verify the requirements, and recommend changes. What should you recommend?
A.The current strategy is enough to test the requirements.
B.Create a unit test for the processor intensive methods.
C.Create a second load test for 20 simultaneous users.
D.Delete the load test and use the Web test with system monitor.
Correct Answers: A

5: 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.)
01      public void Transfer(decimal amount, BankAccount account)
02      {
03        if (!(amount > 0))
04          throw new Exception("Invalid deposit amount!");
05        else
06        {
07          this.Withdraw(amount);
08          account.Deposit(amount);
09        }
10      }
You use the Microsoft Visual Studio 2005 test feature to automatically generate the following unit test. (Line numbers are included for reference only.)
01      [TestMethod()]
02      public void TransferTest()
03      {
05        BankAccount target = new BankAccount();
06        BankAccount transferTo = new BankAccount();
07        target.Deposit(500);
08        target.Transfer(100,transferTo);
09        Assert.Inconclusive("A method that does not return a value cannot be verified.");
10      }
You need to change the test method to return a conclusive result. Which line of code should replace the code on line 09 of the unit test?
A.Assert.AreEqual (400M, target.Balance);
B.Assert.IsTrue (target.Balance != 400M);
C.Debug.Assert (target.Balance == 400M,passed);
D.Debug.Assert (target.Balance == 400M,failed);
Correct Answers: A

6: You create Web-based client applications. You create a Web site that will be used to simulate different types of loans. You are writing a method to calculate the payment on a simple loan. You write the following lines of code for the method. (Comments are included for reference only.)
public static decimal Payment(decimal loanAmount, int period, decimal rate) {
  if (!(loanAmount > 0)||!(period > 1)||!(rate > 0)) { // Line A
     throw new Exception("Invalid input!"); // Line B
  } else {
     return 0M; // Line C: return a calculated payment
}
}
public static decimal CheckBalance(ulong accountID) {
  return 0M; // Line D: return calculated balance
}
You write the following code for the unit test.
[TestMethod()]
public void PaymentTest() {
  decimal payment = Loan.Payment(100000,360,10); // Line E
Assert.AreEqual(payment, 877.57M); // Line F
}
