Show answer and explanation
Correct answer: A
Explanation
The 'show ip route' command is specifically used to verify the contents of the IP routing table on a Cisco device. This table is crucial for understanding how the router forwards packets to different networks. Other commands like 'show interfaces' or 'show running-config' provide useful but unrelated information in this specific scenario.
- A. Correct.
This is the correct command to display the IP routing table, which contains important information about the routes that the router knows and uses.
- B. Incorrect.
This command displays detailed information about the router's interfaces, such as status and traffic statistics, but it does not show routing table information.
- C. Incorrect.
This command displays the current configuration of the router, including IP addresses and interface details, but it does not show the routing table.
- D. Incorrect.
This command provides information about the router's hardware, software version, and uptime, but it is not related to routing information.
