Online Quiz on State Management in ASP.NET



While working in WEB Envrionment with HTTP Protocol it becomes challenging to manage state of web applications as HTTP is stateless protocol. But,State management techniques in ASP.NET are used to maintain user state throughout the application. State management becomes essential while learning WEB Application development,let's have look on how many techniques are there to achieve this,
Main techniques are,
a.Client Side
b.Server Side
c.SQL Server State Management

Client Side State Management Techniques:

  1. ViewState
  2. Hidden fields
  3. Query strings
  4. Cookies
  5. Control state</>

Server Side State Management Techniques:

  1. Application State
  2. Session State
  3. Profile Properties
  4. Database support

In this post I am not going to explain above techniquies in detail rather than I am writing Quiz for above topic to test your knowledge about that.Now you might be thinking that how we will test programming knowledge with Quiz,I know we can test our programming knowledge while actual development/work but we should be aware of the topic what we are going to implement,what is syntax?Is there any impact of your implementation on existing application?what will be performance impact?

So,let's take this simple quiz... ☻☻☻

State management in ASP.NET

Session state
Control state


4.Use __________ when you need to store small amounts of information for a page that will post back to itself or to another page, and when security is not an issue.
Query String
Control state
ViewState
Hidden Fields


5.ASP.NET provides application state via the _______________ class as a method of storing global application-specific information that is visible to the entire application.

Session State
ViewState
Application State
Profile properties


8.Use_____ state management technique,when you are storing user-specific information that needs to be persisted after the user session is expired and needs to be retrieved again on subsequent visits to your application.
Application State
Profile properties
ViewState
Session State


9.Use_____ state management technique,when you are storing large amounts of information, managing transactions, or the information must survive application and session restarts. Also Data mining is a concern, and security is an issue.
