 - Conduct a full UDP port scan (may be all `open|filtered`) because open ports rarely respond to empty probes. No response --> open port or dropped by firewall.

 nmap -A -sV -sC -sU 10.11.1.111 --script=*enum --top-ports 20
 ```
 
 - When version scanning is enabled with -sV (or -A), it will send UDP probes to every `open|filtered` port. If any of the probes elicit a response from an `open|filtered`port, the state is changed to open.
