Cybersecurity-Apprentice Network Fundamentals Practice Question
An administrator configures a Virtual Wire (VWire) interface pair on a Palo Alto Networks firewall. Traffic passing between the two VWire interfaces is intermittently failing. Upon checking, the administrator realizes VLAN tags are being stripped or not matched properly. What setting should be checked in the VWire object configuration?
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
✓
VLAN tagging and subinterface bindings on the Virtual Wire object
Virtual Wire objects support VLAN normalization or VLAN tagging options, and subinterfaces or VWire tags must match expected frame tags.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
VLAN tagging and subinterface bindings on the Virtual Wire object
Why this is correct
Virtual Wire subinterfaces must be properly configured to match tagged frames traversing the transparent wire.
- ✗
DHCP relay agent configuration
Why it's wrong here
DHCP relay is a Layer 3 service unrelated to VWire frame forwarding.
- ✗
Virtual Router next-hop IP addresses
Why it's wrong here
Virtual Wires operate at Layer 2 and do not utilize Virtual Routers or IP next-hops.
- ✗
NAT Destination translation rules
Why it's wrong here
Virtual Wires inspect Layer 2/3 transparently; NAT is a Layer 3 transformation function.
