QUESTION: 18

You are deploying an SRX Series firewall with multiple NAT scenarios.
In this situation, which NAT scenario takes priority?

interface NAT
source NAT
static NAT
destination NAT

Answer(s): A

Explanation:

This is because the interface NAT would allow the connections to pass through the firewall - and thus, would ensure that the appropriate ports are open in order to allow for the connections to be established.
This is a really important step in order to ensure that all of the appropriate traffic is allowed through the SRX Series firewall - and thus, it must be a priority when deploying the firewall.
