Scenario: A network engineer has modified the configuration of a content-switching virtual server,
Website_main, because a second content-switching server that is capable of handling more connections has
been added to the NetScaler implementation. Both servers will remain in operation.
The engineer made the following configuration changes:
>set cs vserver Website_main -lbvserver New_Server -backupVserver Old_Server -redirectURL
http://www.mydomain.com/maintenance -soMethod Connection -soThreshold 1000
Why did the engineer enable the spillover option?

A.
To handle incoming connections in case the new server is unavailable

B.
To handle the extra connections using the old server without dropping them

C.
To redirect the extra connections to the Maintenance website when it is needed

D.
To handle incoming connections while the server reaches its limit of connections
