  1. *PRO TIP* if you follow best practices and change your native VLAN from 1 to something else, it WILL appear in the running config making E correct. Additionally, try running sh int bri on a switch and notice the invalid input detection error. If you enter show int or show int stat you’ll get NOTHING regarding native VLANs making sh int trunk the only remaining answer. If you run that command, you’ll see the trunk ports with their native VLAN noted.

  2. I think “show run” does show the native VLAN

    R2#show run

    interface FastEthernet2/0
    switchport trunk native vlan 20
    switchport mode trunk

  4. I think the correct answer should be B and E

    The command show interface brief does not show a native vlan configured on an interface.
