JNCIA-SEC: Juniper Networks Certified Associate – Security (2021) — Question 65

Which statement is correct about static NAT?

Answer options

• A. Static NAT supports port translation.
• B. Static NAT rules are evaluated after source NAT rules.
• C. Static NAT implements unidirectional one-to-one mappings.
• D. Static NAT implements unidirectional one-to-many mappings.

Correct answer: C

Explanation

The correct answer is C because static NAT creates a fixed one-to-one mapping between a private IP address and a public IP address, ensuring that traffic is routed consistently in one direction. Options A and D are incorrect as static NAT does not support port translation and does not implement one-to-many mappings, while option B is misleading since static NAT rules are typically evaluated before source NAT rules.
