The tracert (Trace Route) command is used to track the path that packets take from a source device to a destination device across a network. This helps technicians identify where traffic is being routed and diagnose connectivity issues. It shows each hop along the path and measures latency between each node. net use (Option A): Used to connect to shared network resources, such as shared folders or printers. Not relevant for tracing traffic. nslookup (Option B): Used for querying DNS servers to resolve domain names to IP addresses. It does not trace network paths. netstat (Option D): Displays active network connections and statistics, but it does not trace routes like tracert does.
