Question:
What is a characteristic of legacy inter-VLAN routing?
- Only one VLAN can be used in the topology.
- The router requires one Ethernet link for each VLAN.
- The user VLAN must be the same ID number as the management VLAN.
- Inter-VLAN routing must be performed on a switch instead of a router.
Explanation: Multiple VLANs are supported with legacy inter-VLAN routing, but each VLAN requires its own Ethernet router link. Ethernet ports are limited on a router. That is why the router-on-a-stick model evolved. The user VLAN should never be the same number as the management VLAN and using a Layer 3 switch as a router is a modern technique, not a legacy one.
