Q

describe the 5 commands involved with

configuring the switch virtual interface (SVI)

A

interface vlan 1 - enter this from global configuration mode to enter the interface sub configuration mode for vlan 1 (NOTE: vlan 1 is the default SVI and is assighned to all interfaces on the switch) (vlan 1 is a virtual interface)
