C.
The Layer 2 protocol of interface Serial 0/1 is NOT operational.
D.
The router is a modular router with five FastEthernet interfaces.
E.
Interface FastEthernet 0/0 is administratively deactivated.
Explanation:
Interface fa0/0 breaks into sub interface and Main_Campus router is connected with
switch via fa0/0 .Subinterfaces configured with different subnet mask so its seem switch has
multiple vlans and allow communication between vlan , router and inter-vlan we need to make a
trunk port.So B will be the correct answer.
