How does a standby Smart Center Server receive logs from all Security Gateways, when an active Smart Center Server fails over?
A . The remote Gateways must set up SIC with the secondary Smart Center Server, for logging.
B . Establish Secure Internal Communications (SIC) between the primary and secondary Servers. The secondary Server can then receive logs from the Gateways, when the active Server fails over.
C . On the Log Servers screen (from the Logs and Masters tree on the gateway object’s General Properties screen), add the secondary Smart Center Server object as the additional log server. Reinstall the Security Policy.
D . Create a Check Point host object to represent the standby Smart Center Server. Then select "Secondary Smart Center Server" and Log Server", from the list of Check Point Products on the General properties screen.
E . The secondary Server’s host name and IP address must be added to the Masters file, on the remote Gateways.
