Juniper JN0-232 Exam - Topic 2 Question 11 Discussion

Zone-based security policies are configured in a context that includes both a source zone and a destination zone. Juniper describes this policy context as from-zone to to-zone, and traffic is classified by matching source zone, destination zone, source address, destination address, and application. Option B is therefore correct. Screens are applied earlier in flow processing than policy evaluation, so option A is incorrect. Security policy lookup is part of first path processing when a session is created; once the session exists, fast path traffic normally follows the established session rather than re-evaluating policy for every packet. Option D is also incorrect because zone-based policies can apply to both intra-zone and inter-zone traffic, depending on the configured context.
