You are designing an ASP.NET Web Forms application.
You expect the application to have high traffic.
You plan to use a Web farm to balance the application load across several Web servers.
You have the following requirements:
– Use round-robin load balancing.
– Do not use persistent storage for session data.
You need to ensure that your design meets the requirements.
Which configuration should you recommend?
A.
Use cookieless session state.
B.
Use the InProc session state mode.
C.
Use the SQLServer session state mode.
D.
Use the StateServer session state mode.
Explanation:
Round-robin DNS The easiest, least expensive, and most common load-balancing mechanism. Simply specify multiple IP addresses for the web server hostname, and browsers will connect to any of the listed IP addresses. If the first IP address a browser attempts to connect to does not respond, the browser will try the next IP address in the list until a server responds. Therefore, round-robin DNS also provides for failover if a single server fails. Round-robin DNS provides server affinity
automatically.
InProc The default, this setting stores session state in the servers memory. Session state is not shared between different web servers, and it is lost if the web server is restarted.
