View Answer / Hide AnswerANSWER: D
Explanation:
InPorc Session Mode:
This is the default session mode in Asp.Net. Its stores session Information in Current Application Domain. There are no requirements of serialization to store data in InProc Session Mode.
StateServer Session Mode:
This is also called Out-Proc session mode. It is managed by aspnet_state.exe. In this mode server may runs on the same system, but it's outside of that main application domain where your web site is running. It is useful in web farm and web garden scenarios.
SQL Server Session Mode:
In this session mode, the Session data is serialized and stored in the SQL Server database. We should use SQL server session mode when we need to implement Session with some more security.
Q.7 Which session modes stores session Information in Current Application Domain?
A) InProc
B) StateServer

InProc session mode stores its session data in a memory object on that application domain. This is handled by worker process in application pool. So if you restart the server you will lose the session data. In web.config file you can mention Session mode and also you have to set the Timeout.
<system.web>
<sessionState mode=”InProc” timeout=”30”>
</system.web>

View Answer / Hide AnswerANSWER: A
Explanation:
View State stores data on client side. It can be used to maintain the State at a page level, it means that the information is being stored for a specific page until that page is active once the user is re-directed or goes to some other page, the information stored in the View State gets lost. You cannot retrieve the ViewState data to some other page.
