Which information is displayed by the command show ip int brief?

• A. A summary of all interfaces including the IPv4 address and the current operational status
• B. The full running configuration of all interfaces
• C. The ARP table for connected devices
• D. The routing table

Answer: (A)

show ip int brief displays a concise snapshot of all interfaces, including the IPv4 address assigned to each interface and the current operational status. It shows whether the interface is up or down at the interface level and whether the line protocol is up, giving you a quick view of which interfaces are active and have addresses. This is not the full running configuration, not the ARP table, and not the routing table—those come from different commands. So you see a summary of interfaces with their IPv4 addresses and whether they’re currently operational.
