FC0-U71 Practice Question: Based on the exhibit, which device is directly…
Exhibit
Refer to the exhibit. Architecture diagram: Internet -> Firewall -> Router -> Switch -> VLAN10 (Sales) and VLAN20 (Engineering).
Based on the exhibit, which device is directly responsible for separating traffic into VLAN10 and VLAN20?
⚠ Common exam trap
It's easy for candidates to confuse the switch's role in VLAN creation with the router's role in inter-VLAN routing, assuming the router separates the VLANs when it only routes between them after the switch has already isolated them.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Switch
The switch is directly responsible for separating traffic into VLAN10 and VLAN20 because VLANs are configured at Layer 2 on a switch, using VLAN tagging (IEEE 802.1Q) to isolate broadcast domains. The switch assigns each port to a specific VLAN, ensuring that frames from VLAN10 are not forwarded to VLAN20 ports without a Layer 3 device.
