Which of the following Windows tools do you use to test IP network connectivity?

The tool used to test IP network connectivity is ping. This utility sends Internet Control Message Protocol (ICMP) echo request packets to the target IP address and waits for a response. A successful response indicates that the network connection between the source and destination is operational, while a lack of a response may suggest issues such as connectivity problems or that the target device is not reachable.

Ping is particularly useful because it provides immediate feedback about the ability to communicate over the network. It helps in determining whether the target device is online, and if so, how quickly it responds, providing round-trip time statistics as well.

Other tools listed serve different purposes. For example, tracert is used to determine the route packets take to reach a network destination, giving insights into the path taken through intermediate routers. Ipconfig provides configuration information regarding the IP addresses and other network settings for the host machine, but does not test connectivity. Route is primarily used to view or modify the local IP routing table, which aids in network configuration but does not directly test connectivity.
