220-1101 - Networking - Section 2.1
Compare and contrast TCP and UDP ports, protocols, and their purposes, including common well-known port numbers and their associated services.
Identify common well-known TCP and UDP ports and the service running on each - HTTP (80), HTTPS (443), SSH (22), RDP (3389), DNS (53), SMTP (25), and DHCP (67/68) among them - and distinguish connection-oriented TCP from connectionless UDP. Recognise which protocols are insecure (Telnet, FTP, HTTP) and the secure replacement a technician should prefer.
