Explanation
A ping sweep is a commonly used method to map live hosts in a network. A ping sweep involves sending a series of ping messages (ICMP Echo Request packets) to a range of IP addresses on a network so as to determine which hosts are currently online. Hosts that are online will respond with a reply message when a ping is sent to them. Collecting the replies makes it possible to map which hosts are currently online on the network (see ISC2 Study Guide, chapter 4, module 3). The remaining options are not typically used to map live hosts in a network. Geolocation is a process for determining a device or user's physical location, based on information obtained from the device's IP or MAC address. Traceroute is a method to determine the sequence of hops that the packets took to a given IP address, so as to both map a network's topology and diagnose connectivity or routing issues. Finally, Wireshark is a network protocol analyzer tool that can be used to view and analyze packets' contents, including the IP addresses and host names.
