   3. VLAN 22 is not created by this process.
   4. VLAN 22 does not exist in that switch until at least one interface is assigned to that VLAN.

   2. The switch should forward frames that arrive in access ports in VLAN 30.
   3. The switch should forward frames that arrive in trunk ports tagged with VLAN 30.
   4. The switch should forward frames that arrive in trunk ports tagged with VLAN 30.

9. The show interfaces g0/1 trunk command provides three lists of VLAN IDs. Which items would limit the VLANs that appear in the first of the three lists of VLANs?

   1. A shutdown vlan 30global command
   2. A switchport trunk allowed vlaninterface subcommand
