In R77, Under what circumstances would IPS bypass be enforced?
A.
Single CoreXL fw instance usage over ‘Low’ threshold, Average Memory over ‘High’ threshold
B.
Average CPU over ‘High’ threshold, Average Memory over ‘Low’ threshold
C.
Single CoreXL fw instance usage over ‘High’ threshold, Average Memory over ‘High’ threshold
D.
Average CPU over ‘High’ threshold, Average Memory over ‘High’ threshold
Explanation:
The IPS Bypass mechanism measures spikes on specific CPU core. Meaning, it may be enabled if one of the CPU cores / CoreXL FW Instances that handles IPS, has reached the configured trigger for Bypass. IPS Bypass trigger is measured as a CPU reading above the High threshold and 9 readings above Low threshold. The IPS Bypass feature is enabled if any CPU core is under heavy load (it uses the busiest CPU core – requires continued load for 10 seconds to enter bypass). It is not measured as average of all active CPU cores.
