Security, Associate (JNCIA-SEC) JN0-232 Exam Questions with Experts Answers Updated Recently

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.

Static NAT creates a fixed one-to-one mapping between real and mapped addresses. Juniper documentation describes static NAT as mapping one IP subnet to another IP subnet and states that translation is limited to one-to-one mappings or address blocks of the same size. This makes option A correct. Juniper also states that no address pools are necessary for static NAT, which makes option C correct. Address pools are commonly associated with source NAT or destination NAT pool configurations, not the basic static NAT mapping model. Static NAT can support static port mapping in specific configurations, but the general static NAT behavior tested here is one-to-one address translation, not dynamic PAT. Therefore, the correct answers are A and C.
