• The wrong VLAN has been configured on GigabitEthernet 0/0.45.
• The command no shutdown is missing on GigabitEthernet 0/0.30.
• The GigabitEthernet 0/0 interface is missing an IP address.
• There is an incorrect IP address configured on GigabitEthernet 0/0.30.
  

  Answers Explanation & Hints: he subinterface GigabitEthernet 0/0.30 has an IP address that does not correspond to the VLAN addressing scheme. The physical interface GigabitEthernet 0/0 does not need an IP address for the subinterfaces to function. Subinterfaces do not require the no shutdown command.
