Network administrators are using the Telnet protocol to administer network devices that are on the 192.168.1.0/24 subnet. Which of the following tools should the administrator use to best identify the devices?
nmap (Network Mapper) is the best tool in this scenario. It can scan the 192.168.1.0/24 subnet to discover live hosts, open ports (like Telnet on port 23), and device types. It’s ideal for mapping and auditing the network.
A. dig is a DNS lookup tool; not useful for identifying hosts on a subnet.
C. tracert shows the path packets take to a destination, not for host discovery.
D. telnet is the protocol being used, not a tool for scanning or identifying devices.
