Which scalable method must be implemented in order to provide inter-VLAN routing on a switched network with more than 1000 VLANs?

• routing traffic internally to a Layer 3 switch device
• configuring static routes on a Layer 2 switch device
• connecting a router interface to a switch port that is configured in trunk mode to route packets between VLANs, with each VLAN assigned to a router subinterface
• connecting each physical router interface to a different physical switch port, with each switch port assigned to a different VLAN

Explanation: Layer 2 switches are able to perform static routing, but this method is inefficient with a large number of VLANs. Multilayer switching is more scalable than any other inter-VLAN routing implementation, with traffic being routed internally to the switch device. In router-on-a-stick inter-VLAN routing, where a single physical interface routes traffic among multiple VLANs on a network, there is no practical scalability. The legacy inter-VLAN routing is very inefficient and is no longer used in switched networks, because each VLAN requires a physical router interface that is connected to a different physical switch port.
