Asp.Net Ultimate Quiz - 10 Technical Questions (Plus A Few Others)

1. ASP.NET separates the HTML output from program logic using a feature named as?

Exception

Code-behind

Code-front

None of the above

ASP.NET separates the HTML output from program logic using a feature named as "Code-behind". This feature allows developers to write the program logic in a separate file, typically with a .cs or .vb extension, while keeping the HTML markup in the .aspx file. The code-behind file contains the event handlers and other server-side code that interacts with the HTML controls on the page. This separation of concerns improves code maintainability and allows for easier collaboration between designers and developers.

2. How do you automatically associate page events and methods in the ASP.NET page framework?

AutoEventWireup attribute of the Page directive is set to true

AutoEventWireup attribute of the Page directive is set to False

It is not possible to set automatically page events and methods

None of the above

When the AutoEventWireup attribute of the Page directive is set to true, the ASP.NET page framework automatically associates page events and methods. This means that the framework will search for methods with specific names (such as Page_Load, Button_Click, etc.) in the code-behind file and wire them up to the corresponding events on the page. This eliminates the need for explicit event handler registration in the code-behind file, making it easier to handle events in ASP.NET pages.

3. Which of the following is true about sessions in ASP.NET?

ASP.NET automatically deletes sessions after a configurable timeout interval

Programmers have to delete sessions after the timeout interval

The default interval time to delete sessions is set at 5 minutes

None of the above

In ASP.NET, sessions are automatically deleted after a configurable timeout interval. This means that programmers do not have to manually delete sessions after the timeout interval. The default interval time to delete sessions is not mentioned in the question, so it is not known whether it is set at 5 minutes or not.

4. The GridView control in ASP.NET has which of the following features?

Automatic data binding

Automatic paging

Both A) and B)

None of the above

The GridView control in ASP.NET has both automatic data binding and automatic paging features. Automatic data binding allows the GridView to bind to a data source and display the data automatically without the need for manual coding. Automatic paging allows the GridView to display a certain number of records per page and automatically generate navigation controls for navigating through the pages of data. Therefore, the correct answer is "Both A) and B)".

5. Which of the following is used to write an error message in the event Log File?

System.Diagnostics

System.EnterpriseServices

System.Data

None of the above

The System.Diagnostics namespace in .NET framework provides classes that allow writing error messages to the event log file. This namespace includes the EventLog class, which allows creating, reading, and writing to event logs on the local or remote computer. Therefore, System.Diagnostics is used to write an error message in the event log file.

6. In an ASP.NET application the Global.asax file lies in which directory?

System

ROOT

Application

None of the above

The Global.asax file in an ASP.NET application lies in the ROOT directory. This file is responsible for handling application-level events and configuring settings for the entire application. It is placed in the ROOT directory so that it can be easily accessed by the application and its events can be triggered when necessary.

7. BONUS QUESTION A software company has developed a web service in which the values of the forms are validated using ASP.NET application. Suppose this web service is adopted and used by a customer, then in such a scenario which of the following is TRUE?

The customer must have technology which can run ASP otherwise it will not function

The customer will only be able to run it on a Microsoft platform

The customer will be able to run it on any platform

None of the above

The web service developed by the software company is using ASP.NET for form validation. ASP.NET is a cross-platform framework that can run on multiple platforms including Windows, macOS, and Linux. Therefore, the customer will be able to run the web service on any platform, not just limited to a Microsoft platform.

8. Which of the following can be used to debug .NET application?

Visual Studio .NET

Runtime Debugger

Systems.Diagnostics classes

All of the above

All of the options mentioned can be used to debug .NET applications. Visual Studio .NET is a widely used integrated development environment (IDE) that provides a comprehensive set of debugging tools. The Runtime Debugger, also known as MDbg, is a command-line tool used for debugging managed code applications. The System.Diagnostics classes in .NET provide various debugging and tracing functionalities that can be utilized to debug applications. Therefore, all of the options mentioned are valid choices for debugging .NET applications.

9. If you wanted to create http handlers in an ASP.NET application which interface would you use?

Pipeline

Handler

IHttpHandlerFactory

None of the above

The correct answer is IHttpHandlerFactory. In an ASP.NET application, if you want to create HTTP handlers, you would use the IHttpHandlerFactory interface. This interface is responsible for creating instances of IHttpHandler, which is used to process incoming HTTP requests and generate the corresponding HTTP responses. By implementing the IHttpHandlerFactory interface, you can customize the creation of HTTP handlers in your application.
