You used Zenmap to scan the 10.20.1.0/24 subnet for open ports. Zenmap is a widely used penetration testing tool and can be customized to suit your needs. From the Target Windows 02 Start menu, open Zenmap (Nmap > Nmap - Zenmap GUI) and edit the Quick Scan Profile to add the ICMP Ping (-PE) option to the Profile and save the changes as Quick Scan your name, replacing your name with your own name. Then run the new Quick Scan your name Profile on the 10.20.1.2 machine. Use screen captures to document your changes and the scan results.
