A. Topology for network 192.168.27.0/24
After conducting multiple network scans using the Nmap utility on the 192.168.27.0/24 IP
address range, eleven active devices were discovered in the range 192.168.27.10 –
192.168.27.20. However, using more detailed scanning options, Nmap was only able to identify
nine of those devices with any degree of certainty.

Scans of the individual devices using the -O switch, Nmap was able to detect the operating system
type and open ports on each device. The network contains three Windows servers, two windows
workstations, one Linux server, two Linux workstations, and a VPN access gateway.
