Palo Alto Networks Exam PCNSE Topic 12 Question 110 Discussion

Actual exam question for Palo Alto Networks's PCNSE exam

Question #: 110
Topic #: 12

Refer to the exhibit. Which will be the egress interface if the traffic's ingress interface is ethernet1/7 sourcing from 192.168.111.3 and to the destination 10.46.41.113?

Aethernet1/6

Bethernet1/3

Cethernet1/7

Dethernet1/5

Show Suggested Answer

Suggested Answer: D

In the second image, VW ports mentioned are 1/5 and 1/7. Hence it can not be a part of any other routing. So if any traffic coming as ingress from 1/7, it has to go out via 1/5.

The egress interface for the traffic with ingress interface ethernet1/7, source 192.168.111.3, and destination 10.46.41.113 will beethernet1/5.This is because the traffic will match the virtual wire with interfaces ethernet1/5 and ethernet1/7, which is configured to allow VLAN-tagged traffic with tags 10 and 201.The traffic will also match the security policy rule that allows traffic from zone Trust to zone Untrust, which are assigned to ethernet1/7 and ethernet1/5 respectively2.Therefore, the traffic will be forwarded to the same interface from which it was received, which is ethernet1/53.

Haha, this question is a real brain-teaser! I'm going with D. ethernet1/5 just to keep the networking gods on their toes.

I'm pretty confident the answer is A. ethernet1/6. That's probably the interface connected to the network where the destination 10.46.41.113 is located.

I'm not sure about this one. I'd say C. ethernet1/7, since that's the ingress interface and the traffic might just be looping back out the same way it came in.

That makes sense, but I'm still not sure. Maybe we should review the exhibit again.

I believe it will be ethernet1/7 because the traffic is coming from that interface.

Hmm, I think the answer is B. ethernet1/3, since the traffic is destined for a different network and the router needs to forward it through the appropriate interface.
