You have completed developing a new software application. To ensure the quality of the software, you need to verify that each method or function has proper test cases available. Which testing approach should you use?
- A.
White-box testing
- B.
Black-box testing
- C.
Alpha testing
- D.
Beta testing
Correct Answer
A. White-box testingExplanation
Black-box testing treats the software as a “black box,” focusing solely on inputs and outputs. On the other hand, white-box testing is used to make sure that each method or function has proper test cases available. Alpha and beta testing are both black-box types of testing.Rate this question:

You have completed developing several major features of a new software application. You plan to provide an early look at the product to important customers to gather some early feedback. Your application still misses features and you haven’t yet optimized the application for perforce and security. Which kind of testing should you perform with a limited number of important customers?
- A.
White-box testing
- B.
Black-box testing
- C.
Alpha testing
- D.
Beta testing
Correct Answer
C. AlpHa testingExplanation
Alpha testing—performed by a limited group of users—provides opportunities to give the most important customers an early look at the product and to gather feedback. Alpha releases may miss some features and generally lack many nonfunctional attributes such as performance. In the next level of testing, beta testing, you release the product to a wider audience of customers and solicit feedback. In terms of functionality, the beta release of the software is very close to the final release. However, the development teams might still be working on improving performance and fixing known defects.Rate this question:

Which data structure should you use to implement such a buffer?
- A.
Array
- B.
Linked list
- C.
Stack
- D.
Queue
Correct Answer
D. QueueExplanation
In a queue, items are processed in the order in which they were added to the queue. In particular, items are always added at the end of the queue and removed from the front of the queue. This is also commonly known as first-in, first-out (FIFO) processing.Rate this question:

You are developing an application that uses a double dimensional array. You use the following code to declare the array: int[,] numbers = new int[,] { { 11, 7, 50, 45, 27 }, { 18, 35, 47, 24, 12 }, { 89, 67, 84, 34, 24 }, { 67, 32, 79, 65, 10 } }; Next, you refer to an array element by using the expression numbers[2, 3]. What will be the return value of this expression?
- A.
47
- B.
84
- C.
24
- D.
34
Correct Answer
D. 34Explanation
In the .NET Framework, all arrays are zero-based. A two-dimensional array can be thought of as a table in which each cell is an array element and can be addressed using the numbers of the row and column to which it belongs. Both the row number and column number are indexed by zero. For example, the expression number[2, 3] would refer to an item in the third row and fourth column of an array, which in this case is 34.Rate this question:

You are developing an application that uses the Stack data structure. You write the following code: Stack first = new Stack(); first.Push(50); first.Push(45); first.Pop(); first.Push(11); first.Pop(); first.Push(7); What are the contents of the stack, from top to bottom, after these statements are executed?
- A.
7, 11, 50
- B.
7, 45
- C.
7, 50
- D.
7, 11, 45
Correct Answer
C. 7, 50Explanation
After the first statement, the content of the stack is (50). After the second statement, the stack contents from top to bottom are (45, 50). After the third statement, the top element is popped, resulting to (50). After the fourth statement, another element is added to the top, resulting to (11, 50). After the fifth statement, the top element is popped, resulting to (50). Finally, the sixth statement is executed and the result of stack is (7, 50).Rate this question:

- B.
Push
- C.
Peek
- D.
Contains
Correct Answer
C. PeekExplanation
The peek operation allows you to look at the current item at the top of the stack without actually removing it. The contains operation allows you to determine whether a particular item exists in the stack. The push operation adds an item to the top of the stack. The pop operation removes the element at the top of the stack.Rate this question:

You are developing a sorting algorithm that uses partitioning and comparison to arrange an array of numbers in the correct order. You write a method that partitions the array so that the items less than pivot go to the left side, whereas the items greater than pivot go to the right side. The partitioning method has the following signature: static int Partition (int[] numbers, int left, int right, int pivotIndex) Which of the following algorithms should you use to sort the array using the Partition method?
- A.
Static int[] QuickSort(int[] numbers, int left, int right) { if (right > left) { int pivotIndex = left + (right - left) / 2; pivotIndex = Partition( numbers, left, right, pivotIndex); QuickSort( numbers, left, pivotIndex - 1); QuickSort( numbers, pivotIndex + 1, right); } return numbers; }
- B.
Static int[] QuickSort(int[] numbers, int left, int right) { if (right > left) { int pivotIndex = left + (right - left) / 2; pivotIndex = Partition( numbers, left, right, pivotIndex); QuickSort( numbers, left, pivotIndex); QuickSort( numbers, pivotIndex + 1, right); } return numbers; }
- C.
Static int[] QuickSort(int[] numbers, int left, int right) { if (right > left) { int pivotIndex = left + (right - left) / 2; pivotIndex = Partition( numbers, left, right, pivotIndex); QuickSort( numbers, left, pivotIndex - 1); QuickSort( numbers, pivotIndex, right); } return numbers; }
- D.
Static int[] QuickSort(int[] numbers, int left, int right) { if (right > left) { int pivotIndex = left + (right - left) / 2; pivotIndex = Partition( numbers, left, right, pivotIndex); QuickSort( numbers, left, pivotIndex + 1); QuickSort( numbers, pivotIndex + 1, right); } return numbers; }
Correct Answer
A. Static int[] QuickSort(int[] numbers, int left, int right) { if (right > left) { int pivotIndex = left + (right - left) / 2; pivotIndex = Partition( numbers, left, right, pivotIndex); QuickSort( numbers, left, pivotIndex - 1); QuickSort( numbers, pivotIndex + 1, right); } return numbers; }Explanation
After you partition the array, you need only to sort the left and right sides of the array. The middle element is automatically sorted.
To sort the left array, use the expression QuickSort( numbers, left, pivotIndex - 1); to sort the right array, you should use the expression QuickSort(numbers, left, pivotIndex + 1).Rate this question:

You are developing a C# program that makes use of a singly linked list. You need to traverse all nodes of the list. Which of the following items will you need to accomplish this requirement?
- A.
Link to the head node
- B.
Link to the tail node
- C.
Data in the head node
- D.
Data in the tail node
Correct Answer
A. Link to the head nodeExplanation
Each node in a linked list contains of two pieces of information: the data corresponding to the node, and the link to the next node.
The first node of the list is called the head node. Using this link, you can get to the next node and continue traversing nodes until the final link is a null value.Rate this question:
-
- 19.
Which of the following is not true about linked lists?
- A.
A linked list does not allow random access to its items.
- B.
A link to the head node can help you locate all the nodes in a linked list.
- C.
The items in a linked list must be stored in contiguous memory locations.
- D.
Linked lists are extremely fast in performing insert and delete operations.
Correct Answer
C. The items in a linked list must be stored in contiguous memory locations.Explanation
A linked list is a collection of nodes in which each node contains a reference (or link) to the next node in the sequence.
Unlike in an array, items in a linked list need not be contiguous; therefore, a linked list does not require reallocation of memory space for the entire list when more items must be added.Rate this question:

You are developing a program that performs frequent insert and delete operations on the data. Your requirement also dictates the capability to access previous and next records when the user clicks the previous or next button. Which of the following data structures will best suit your requirements?
- A.
Array
- B.
Circular linked list
- C.
Linked list
- D.
Doubly linked list
Correct Answer
D. Doubly linked listExplanation
Because you need to perform frequent insert and delete operations, using a linked list is better than using arrays.
Also, because you need access to both previous and next records, you must use a doubly linked list.
The linked list and circular linked list let you traverse in only one direction.Rate this question:

You need to perform data validation to ensure that the input fields are not empty and the user’s email address and phone numbers have been provided in the required format. You need to minimize the transmission of information across the networks. Which of the following coding approaches should you follow?
- A.
Use JavaScript code that executes on the Web server.
- B.
Use C# code that executes on the Web server.
- C.
Use JavaScript code that executes in the browser.
- D.
User C# code that executes in the browser.
Correct Answer
C. Use JavaScript code that executes in the browser.Explanation
JavaScript is a client-side scripting language that runs inside Web browsers to help create far more interactive Web pages than are possible with only HTML.
C# code does not run within Web browsers.
Writing code that runs on a Web server increases transmission of information across networks and provides slow response to the users.Rate this question:

You write large amount of JavaScript code for your Web site. You need to take advantage of caching techniques to make sure that Web pages load as quickly as possible. You also need to ensure that you can modify the JavaScript code with the least amount of effort. What should you do?
- A.
Write JavaScript code inside the SCRIPT tag. Include the SCRIPT within the HEAD tag of the HTML page.
- B.
Write JavaScript code inside the SCRIPT tag. Include the SCRIPT within the BODY tag of the HTML page.
- C.
Write JavaScript code in a separate file. Use the SRC attribute of the SCRIPT tag to link to the JavaScript file.
- D.
Write JavaScript code in a separate file. Use the HREF attribute of the LINK tag to link to the JavaScript file.
Correct Answer
C. Write JavaScript code in a separate file. Use the SRC attribute of the SCRIPT tag to link to the JavaScript file.Explanation
You should write JavaScript code in a separate file and then use the SRC attribute of the SCRIPT tag to link to the JavaScript file. When the JavaScript code is in an external file, it can be cached on the client side and doesn’t need to be downloaded with every page.
Writing the JavaScript code inside the SCRIPT code and including the SCRIPT tag within HEAD or BODY increases the Web page’s size and causes the JavaScript code to be downloaded with each page request, thereby slowing down page loads.
Using the LINK tag will not work because it is used to link to the external CSS file.Rate this question:

Which of the following processes is responsible for providing the ASP.NET functionality?
- A.
Inetinfo.exe
- B.
Iexplore.exe
- C.
Aspnet_isapi.dll
- D.
Aspnet_wp.exe
Correct Answer
D. Aspnet_wp.exeExplanation
The aspnet_wp.exe (ASP.NET Worker Process) file handles the Web requests for ASP.NET resources. The ASP.NET ISAPI extension (aspnet_isapi.dll) is responsible for invoking the ASP.NET worker process (aspnet_wp.exe), which, in turn, controls the execution of the request.
The inetinfo.exe is the Internet Information Services process.
The iexplore.exe process is for the Internet Explorer Web browser.Rate this question:

You are developing an ASP.NET Web page that displays status of a shipment. You need to write some code that will change the Web page’s appearance and assign values to some controls. Where should you put this code?
- A.
In the InitializeComponent method
- B.
In a method that handles the Load event
- C.
In a method that handles the Init event
- D.
In a method that handles the PreRender event
Correct Answer
B. In a method that handles the Load eventExplanation
The method that handles the Load event is the most appropriate place for writing initialization code such as this.
You should not be including the Visual Studio InitializeComponent method in your code. The method that handles the Init event does not have access to the controls because they are available only after the page is initialized.
If you write the code in the method that handles the PreRender event, any changes to the control’s properties do not have a visible effect because the page is already ready to be rendered.Rate this question:

You write the following code in your Web page: protected void Page_Load (object sender, EventArgs e) { /* additional code here */ } You expect this code to be executed in response to the Load event of the ASP.NET page. However, when you request the page, you notice that the method is not executed. What should you do to make sure that the Page_Load method is executed when the Load event of the Web page is fired?
- A.
Set the AutoEventWireup attribute of the @Page directive to true.
- B.
Set the AutoEventWireup attribute of the @Page directive to false.
- C.
Set the IsCallBack property of the Page class to true.
- D.
Set the IsPostBack property of the Page class to true.
Correct Answer
A. Set the AutoEventWireup attribute of the @Page directive to true.Explanation
When the AutoEventWireup attribute of the @Page directive is set to true, specially named methods such as Page_Load are automatically wired up with their corresponding events. When the AutoEventWireup attribute of the @Page directive is set to false, the Page_Load method is not associated with the Load event of the Page class. The IsCallBack property of the Page class indicates whether the page request is the result of a callback.
The IsPostBack property of the Page class indicates whether the page request is the result of a post-back operation.Rate this question:

- A.
Script runat="server" … /script
- B.
Script ... /script
- C.
% … %
- D.
Noscript ... /noscript
Correct Answer
D. Noscript ... /noscriptExplanation
Use noscript element to display a specific message to users when their browser is not running JavaScript.
The script tag is ignored when JavaScript is not enabled.
The % ... % and script runat="server" … /script tags are used only for server-side programming.Rate this question:

You are developing an ASP.NET application using C#. On your Web page, you want to display the results returned by a C# method named GetShipmentStatus when the page is rendered to the client. Which of the following code segments should you use to call the GetShipmentStatus method?
- A.
Script language="c#" runat="server" Response.Write(GetShipmentStatus()); /script
- B.
Script language="c#" runat="client" Response.Write(GetShipmentStatus()); /script
- C.
Script language="c#" Response.Write(GetShipmentStatus()); /script
- D.
%= GetShipmentStatus() %
Correct Answer
D. %= GetShipmentStatus() %Explanation
The %= ... % construct is used to display values from ASP.NET code, such as a method call. Using the script tag is incorrect because this tag is used for defining class-level methods, properties, and variables.Rate this question:

- A.
% Page Language="c#" Codebehind="status.aspx.cs" ClassName="Northwind.Status" %
- B.
% Page Language="c#" Codebehind="status.aspx.cs" Inherits="Northwind.Status" %
- C.
% Page Language="c#" Src="status.aspx.cs" Inherits="Northwind.Status" %
- D.
% Page Language="c#" Src="status.aspx.cs" ClassName="Northwind.Status" %
Correct Answer
C. % Page Language="c#" Src="status.aspx.cs" Inherits="Northwind.Status" %Explanation
The Inherits attribute in the @Page directive specifies a fully qualified name of the code-behind class from which the code should inherit. The Src attribute specifies the name of the source code file. The Codebehind attribute is used only by Visual Studio and is not used at runtime. The Classname attribute does not link ASP.Net pages with the code-behind class or file.Rate this question:
