3.1.2 Inter-VLAN Routing using Layer 3 Switches

A PC is to access a web server on another network. Which inter-VLAN method will provide the highest bandwidth at Layer 3 and also provide a default gateway for the PC?

• Router on a stick.

• Multilayer switch with routing enabled.

• Trunked interface between the router and the switch.

• Multiple physical interfaces on the router, all connected to a Layer 2 switch.

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.

• 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.

What is a disadvantage of using multilayer switches for inter-VLAN routing?

• Multilayer switches have higher latency for Layer 3 routing.

• Multilayer switches are more expensive than router-on-a-stick implementations.

• Spanning tree must be disabled in order to implement routing on a multilayer switch.

• Multilayer switches are limited to using trunk links for Layer 3 routing.

A network administrator enters the following command sequence on a Cisco 3560 switch. What is the purpose of these commands?

Switch(config)# interface gigabitethernet 0/1
Switch(config-if)# no switchport

• To shut down the Gi0/1 port.

• To make the Gi0/1 port a routed port.

• To enable the Gi0/1 port as a switch virtual interface.

• To enable the Gi0/1 port as a bridge virtual interface.

Which sentence correctly describes the SVI inter-VLAN routing method?

• Subinterfaces have to be created.

• The encapsulation type must be configured on the SVI.

• An SVI is needed for each VLAN.

• A physical interface is needed for every VLAN that is created.
