Explanation

Based on the referenced exhibit (a 'show interfaces' or 'show ip interface brief' output on R2), the correct answer is C - the interfaces are functioning correctly. In Cisco IOS, a fully operational interface shows a status of 'up' (physical layer) and a line protocol of 'up' (data link layer). If the exhibit shows all of R2's interfaces in an 'up/up' state with valid IP addresses, that confirms normal operation. An interface showing 'up/down' indicates a data link issue, 'down/down' indicates a physical layer problem, and 'administratively down' means it was manually shut down.
