JNCIA-SEC: Juniper Networks Certified Associate – Security (2021) — Question 11

Which statement about global NAT address persistence is correct?

Answer options

• A. The same IP address from a source NAT pool will be assigned for all sessions from a given host.
• B. The same IP address from a source NAT pool is not guaranteed to be assigned for all sessions from a given host.
• C. The same IP address from a destination NAT pool will be assigned for all sessions for a given host.
• D. The same IP address from a destination NAT pool is not guaranteed to be assigned for all sessions for a given host.

Correct answer: A

Explanation

Answer A is correct because it states that a single IP address from a source NAT pool is consistently assigned to all sessions originating from a specific host. Meanwhile, option B contradicts this by suggesting inconsistency, while options C and D incorrectly reference destination NAT pools instead of source NAT pools.
