What is an example of a network configuration test command?

All of the options listed—route, nslookup, and tracert—are valid network configuration test commands used for different purposes in managing and troubleshooting networks.

The route command is used to view and manipulate the IP routing table on a computer or router. It allows network administrators to see how data packets are routed through the network, which is crucial for configuring network settings and diagnosing routing issues.

Nslookup is a command-line tool used to query DNS servers to obtain domain name or IP address mapping information. This is useful in verifying DNS configurations, ensuring that names resolve correctly to their corresponding IP addresses.

Tracert (or traceroute in Unix/Linux) is used to trace the path that packets take from one device to another across a network. It provides valuable network path information, including the time taken for each hop along the route, which helps in diagnosing network performance issues and identifying points of failure.

Since all three commands serve specific purposes in testing and configuring network settings, selecting the option that states "all of the above" recognizes that they are all valid examples of network configuration test commands.
