Refer to the exhibit.
What information about the interfaces on the Main_Campus router is true?
A.
The LAN interfaces are configured on different subnets.
B.
Interface FastEthernet 0/0 is configured as a trunk.
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-interfaces and Main_Campus router is connected with switch via
fa0/0 .Subinterfaces configured with different subnet mask so the seem switch has multiple vlans
and allows communication between these VLAN’s. For routing and inter-vlan we need to configure a
trunk port. So B will be the correct answer.
