CCNA Routing and Switching (legacy) — Question 58

Which router IOS commands can be used to troubleshoot LAN connectivity problems? (Choose three.)

Answer options

• A. ping
• B. tracert
• C. ipconfig
• D. show ip route
• E. winipcfg
• F. show interfaces

Correct answer: A, D, F

Explanation

The commands 'ping', 'show ip route', and 'show interfaces' are effective for diagnosing LAN connectivity issues. 'ping' checks connectivity to other devices, 'show ip route' provides route information, and 'show interfaces' displays the status of network interfaces. In contrast, 'tracert', 'ipconfig', and 'winipcfg' are either not IOS commands or are more relevant to troubleshooting on a local device rather than a router.
