Exam 156-590 Topic 1 Question 66 Discussion

The correct answer is B. Traffic is matched against all applicable layers at the same time . Threat Prevention policy evaluation is not best described as a flat simultaneous match against all applicable layers.
Check Point documentation explains that Threat Prevention Policy Layers are Ordered Layers , and that each ordered layer calculates its action separately from the other layers. In a single-layer policy package, the enforced rule is the first matched rule. In multiple-layer policy behavior, matching and enforcement are determined by the layer calculations and the applicable action logic, rather than by one undifferentiated simultaneous match model.
Option A is true because Threat Prevention inspection is applied after the Access Control policy allows the connection; traffic dropped or rejected by Access Control does not proceed to Threat Prevention enforcement.
Option C is true for a single Threat Prevention layer because the first matching rule is enforced. Option D is also true because Threat Prevention uses ordered policy-layer behavior. The false statement is therefore option B.
