Which port does HTTPS typically use and which protocol provides encryption?

• A. Port 80; uses UDP with DTLS
• B. Port 22; uses TCP with TLS
• C. Port 443; uses TCP with TLS/SSL
• D. Port 53; uses UDP with TLS

Answer: (C)

HTTPS secures web traffic by wrapping HTTP in TLS encryption, and it uses port 443 by default. Because web communication needs reliable delivery, HTTPS runs over TCP rather than UDP. TLS provides the encryption (SSL is the older name often seen, but modern use is TLS). So the standard setup is port 443 with TCP and TLS/SSL encryption. The other options mix in unencrypted HTTP (port 80), a different service (SSH on port 22), or DNS transport (port 53) which isn’t how HTTPS operates.
