Which three Windows CLI commands and utilities can a technician use to verify PC connectivity to local and Internet resources?

The command that is primarily used to verify connectivity to both local and Internet resources is the ping command. When a technician uses ping, it sends Internet Control Message Protocol (ICMP) echo request packets to the target IP address or domain name. If the target is reachable and responsive, it will reply with echo reply packets. This makes the ping command an effective tool for checking the reachability of a host, determining if the target is active on the network, and measuring the round-trip time for messages sent to the destination.

The other commands and utilities, while useful in different contexts, serve varying purposes. For instance, ipconfig is primarily utilized to display the current network configuration of the PC, showing details such as IP address, subnet mask, and gateway. This information is critical for understanding the configuration but doesn't directly test connectivity.

Similarly, nslookup is a network administration command-line tool used for querying the Domain Name System (DNS) to obtain domain name or IP address mapping information. While it does help in verifying if DNS resolution is functioning correctly, it doesn't provide a direct connectivity check like ping does.

On the other hand, tracert (traceroute) is a utility that traces the path packets take to a destination across an IP network. It
