Palo Alto Networks Exam PCNSE Topic 4 Question 83 Discussion

Actual exam question for Palo Alto Networks's PCNSE exam

Question #: 83
Topic #: 4

Why are external zones required to be configured on a Palo Alto Networks NGFW in an environment with multiple virtual systems?

ATo allow traffic between zones in different virtual systems without the traffic leaving the appliance

BTo allow traffic between zones in different virtual systems while the traffic is leaving the appliance

CExternal zones are required because the same external zone can be used on different virtual systems

DMultiple external zones are required in each virtual system to allow the communications between virtual systems

Show Suggested Answer

Suggested Answer: A

External zones are a unique zone type on Palo Alto Networks firewalls that facilitate the movement of traffic between virtual systems on the same physical appliance. These zones are required when multiple virtual systems (vsys) are configured on a single firewall and there is a need to allow inter-vsys traffic without the need for the traffic to leave the firewall and re-enter. An external zone is associated with a specific virtual system and enables traffic to pass from one virtual system to another securely, thereby simplifying traffic management and reducing the need for additional physical interfaces or external routing to handle inter-vsys communication.

Hmm, I'm leaning more towards option C. I think the idea is that the same external zone can be used across different virtual systems, which would make management a bit easier.

This question seems a bit tricky. At first glance, I'm thinking that option A might be the correct answer, as it would allow traffic between zones in different virtual systems without leaving the appliance.
