Refer to the topology below.

What interfaces on Router1 have not had any configurations applied? (Choose two)

A.
Ethernet 0

B.
FastEthenet 0/0

C.
FastEthernet 0/1

D.
Serial 0

E.
Serial 0/0

F.
Serial 0/1

Explanation:

Use the show ip interface brief to identify what interfaces Router 1 have. Notice that Router1 does
not have Ethernet 0 and Serial 0 interfaces. FastEthernet 0/0 and Serial 0/0 were configured with
their IP addresses therefore only FastEthernet 0/1 and Serial0/1 have not had any configurations
applied.
