200-901 Practice Question: Based on the exhibit, which interface is in a…
Exhibit
Refer to the exhibit. Router# show ip interface brief Interface IP-Address OK? Method Status Protocol GigabitEthernet0/0 192.168.1.1 YES manual up up GigabitEthernet0/1 10.10.10.1 YES manual down down GigabitEthernet0/2 unassigned YES unset administratively down down
Based on the exhibit, which interface is in a down/down state (both Status and Protocol are down)?
⚠ Common exam trap
Cisco often tests the ability to read the 'show interfaces' output correctly, where candidates may confuse the 'Status' and 'Protocol' columns or misinterpret an 'up/up' state as a problem, leading them to select a wrong interface like GigabitEthernet0/0 or GigabitEthernet0/2.

Correct answer & explanation
✓
GigabitEthernet0/1
The exhibit shows that GigabitEthernet0/1 has both Status and Protocol listed as 'down'. In Cisco IOS, the 'Status' column indicates the line protocol state (Layer 1), and the 'Protocol' column indicates the data link layer state (Layer 2). When both are 'down', the interface is administratively down or has a physical layer issue, such as a disconnected cable or a shutdown command.
