Cybersecurity-Apprentice Network Security Practice Question
An organization deploys a Palo Alto Networks firewall in 'Virtual Wire' mode. How does this deployment mode process incoming Ethernet frames?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It inspects and passes traffic inline between two ports without requiring IP addresses or MAC switching tables.
Virtual Wire (vWire) binds two physical interfaces together and passes all traffic inline at layer 1/2 without performing IP routing or MAC switching.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It routes packets between multiple VLAN subnets using layer 3 gateway IPs.
Why it's wrong here
Layer 3 subnets and routing are handled by Layer 3 interfaces.
- ✗
It terminates VPN tunnels and assigns DHCP leases to remote clients.
Why it's wrong here
GlobalProtect or DHCP server features handle this, not virtual wire mode.
- ✓
It inspects and passes traffic inline between two ports without requiring IP addresses or MAC switching tables.
Why this is correct
Virtual wire acts like a transparent cable connecting two network segments.
- ✗
It switches Ethernet frames across multiple ports using Spanning Tree Protocol.
Why it's wrong here
Layer 2 interfaces use MAC switching and STP, not virtual wire.
