Which scalable method must be implemented in order to provide inter-VLAN routing on a switched network with more than 1000 VLANs?. Configuring static routes on a Layer 2 switch device. Routing traffic internally to a Layer 3 switch device. Connecting each physical router interface to a different physical switch port, with each switch port assigned to a different VLAN.
