200-901 Practice Question: Is troubleshooting a connectivity issue between…
A network engineer is troubleshooting a connectivity issue between two hosts in different VLANs on the same switch. The hosts are in VLAN 10 and VLAN 20, respectively. The switch has an SVI for each VLAN and IP routing is enabled. Which command should be used to verify that the switch is forwarding traffic between the VLANs?
⚠ Common exam trap
Cisco often tests the misconception that 'show vlan' or 'show interfaces trunk' can verify inter-VLAN routing, when in fact those commands only confirm Layer 2 connectivity and VLAN membership, not the Layer 3 routing table.
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
✓
show ip route
'show ip route' displays the switch's routing table, which contains the directly connected subnets for VLAN 10 and VLAN 20 (via their SVIs) and any learned routes. Since IP routing is enabled, the switch uses this table to make forwarding decisions between VLANs. Verifying that both VLAN subnets appear in the routing table confirms that the switch can route traffic between them.
