Common mistakes.

A. Port scanning targets specific known hosts to identify which TCP/UDP ports are open and listening, not to discover which hosts exist on the network in the first place.
B. Vulnerability scanning probes already-identified hosts for known security weaknesses, misconfigurations, or missing patches - it presupposes that the hosts have already been enumerated.
C. GPS mapping refers to geolocation and physical cartography and is not a recognized network security or reconnaissance activity.
