Question
Why are external zones required to be configured on a Palo Alto Networks NGFW in an environment with multiple virtual systems?
A. To allow traffic between zones in different virtual systems while the traffic is leaving the appliance
B. External zones are required because the same external zone can be used on different virtual systems
C. To allow traffic between zones in different virtual systems without the traffic leaving the appliance
D. Multiple external zones are required in each virtual system to allow the communications between virtual systems
Answer
C. To allow traffic between zones in different virtual systems without the traffic leaving the appliance
Explanation
External zones are required to be configured on a Palo Alto Networks NGFW in an environment with multiple virtual systems to allow traffic between zones in different virtual systems without the traffic leaving the appliance. This is achieved by configuring the virtual systems so that they are visible to each other. The traffic can flow from one trust zone, out an external zone, into an external zone of another virtual system, and into its trust zone.
