Juniper JN0-232 Exam - Topic 2 Question 12 Discussion

In the JNCIA-SEC SRX security policy context, standard security policies control transit traffic passing through the firewall. They are not the normal mechanism for permitting management or protocol traffic destined to the SRX itself; that type of self or exception traffic is controlled with host-inbound-traffic settings. Security policies can be configured between different zones, which is inter-zone policy, or within the same zone, which is intra-zone policy. Therefore, option C is correct because policies can apply to both intra-zone and inter-zone flows. Option D is correct in the standard SRX policy model because security policies are used to control traffic transiting the firewall. Options A and B are not correct for this topic scope.
