3.1 Inter-VLAN Routing

When configuring a router as part of a router-on-a-stick inter-VLAN routing topology, where should the IP address be assigned?

• To the interface

• to the subinterface

• to the SVI

• To the VLAN

A small college uses VLAN 10 for the classroom network and VLAN 20 for the office network. What is needed to enable communication between these two VLANs while using legacy inter-VLAN routing?

• A router with at least two LAN interfaces should be used.

• Two groups of switches are needed, each with ports that are configured for one VLAN.

• A router with one VLAN interface is needed to connect to the SVI on a switch.

• A switch with a port that is configured as trunk is needed to connect to a router.

What is a disadvantage of using router-on-a-stick inter-VLAN routing?

• Does not support VLAN-tagged packets.

• Requires the use of more physical interfaces than legacy inter-VLAN routing.

• Does not scale well beyond 50 VLANs.

• Requires the use of multiple router interfaces configured to operate as access links.

What is the meaning of the number 10 in the encapsulation dot1Q 10 native router subinterface command?

• The interface number.

• The subinterface number.

• The subnet number.

• The VLAN ID.

Which type of inter-VLAN communication design requires the configuration of multiple subinterfaces?

• Router on a stick.

• Routing via a multilayer switch.

• Routing for the management VLAN.

• Legacy inter-VLAN routing.
