Of the options provided, the three router IOS commands that can be used to troubleshoot LAN connectivity problems are:

  1. Ping: Ping is a tool used to test network connectivity between devices. It sends packets of data to a specific IP address and waits for a response. If a response is received, it indicates that the target device is reachable and there is no connectivity issue. If there is no response, it may indicate a problem with the network or the device itself.

  2. Show interfaces: This command is used to display the status and configuration of all interfaces on a router. By using this command, you can check the status of a particular interface to determine if it is up or down, if it has any errors or if it has been configured correctly. This information can help you identify connectivity issues and troubleshoot them.

  3. Show ip route: This command displays the routing table on a router, which contains information about the available paths to reach different networks. By using this command, you can check if the router has a route to the network you are trying to reach, and if there are any issues with the routing configuration.

The other options provided, such as winipcfg, tracert, and ip config are not router IOS commands, but rather commands used on different operating systems. Winipcfg is a command used in Windows to view IP configuration details, tracert is a command used to trace the path packets take through a network, and ip config is a command used to display IP configuration information on a computer. These commands are not applicable to router IOS troubleshooting.
