Which two statements correctly describe static NAT?

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.
