Which of the below technology(ies) could reduce CPU load and memory utilization used by an IPS engine?
A.
IPS does not compare traffic to each signature individually. Instead it compiles them into a decision tree
B.
Using IPS sensors and IPS filter to determine which traffic should be examined for which signatures, instead of examine network traffic for all signatures
C.
Using multiple engines, aligned with load balancing technologies like Turbo that uses round robin algorithms to dispatch traffic up to specific IPS engine
D.
Using regular instead of extended database, to reduce memory footprint
IPS efficiency is improved by: A) Compiling signatures into a decision tree to reduce comparison overhead; B) Using IPS sensors/filters to selectively apply signatures to relevant traffic, reducing unnecessary processing; D) Using a regular database instead of an extended one to lower memory usage. Option C’s “Turbo” and round-robin load balancing is not a standard Fortinet IPS feature. Option E is incorrect as C is not valid. Exact extract: "IPS efficiency is improved by compiling signatures into decision trees to minimize CPU usage... IPS sensors and filters allow selective signature application to reduce processing... Using the regular signature database instead of extended reduces memory footprint."
