Which router IOS commands can be used to troubleshoot LAN connectivity problems?
Which router IOS commands can be used to troubleshoot LAN connectivity problems? (Choose three.)
The ping command can be used to test if the local device can reach a specific destination -> A is correct.
“tracert” is not a valid command in Cisco IOS commands, the correct command should be “traceroute” -> B is not correct.
The ipconfig command is not a valid command in Cisco IOS too -> C is not correct.
The “show ip route” command can be used to view the routing table of the router. It is a very useful command to find out many connectivity problems (like directly connected networks, learned network via routing protocols…) -> D is correct.
“winipcfg” is an old tool in Windows 95/98 to view IP settings of the installed network interfaces. But it is not a valid command in Cisco IOS commands -> E is not correct.
The “show interfaces” command is used to check all the interfaces on the local device only. It has very limited information to trouble LAN connectivity problem but it is the most reasonable to choose -> F is acceptable.
