- A
show ip route
- B
show interfaces
- C
show ip interface brief
- D
show running-config
Show answer and explanation
Correct answer: C
Explanation
To quickly verify the IP addresses assigned to interfaces and their operational status on a Cisco device, the 'show ip interface brief' command is the most appropriate. This command provides a concise and easy-to-read summary, making it ideal for troubleshooting connectivity issues.
- A. Incorrect.
The 'show ip route' command displays the routing table of the device, showing the available routes and their next hops. While useful for routing issues, it does not provide information about IP addresses assigned to interfaces or their operational status.
- B. Incorrect.
The 'show interfaces' command provides detailed information about each interface, including statistics and errors, but it is not a concise summary of IP addresses and their statuses, making it less optimal for this scenario.
- C. Correct.
The 'show ip interface brief' command provides a concise summary of all interfaces, their assigned IP addresses, and their operational and administrative status, making it the correct choice for this scenario.
- D. Incorrect.
The 'show running-config' command displays the current configuration of the device, including interface configurations. However, it is not designed to provide real-time operational statuses of the interfaces.
