A system administrator is configuring network firewall rules for a web server host that must accept both standard unencrypted web browsing traffic and secure encrypted web browsing traffic. Which of the following port numbers must be permitted through the firewall to allow this functionality? (Select TWO.)
- Port 80Cevap
- Port 443Cevap
- CPort 53
- DPort 22
Cevap
Port 80 (HTTP) and Port 443 (HTTPS) must be allowed through the firewall.
Port 80 is the standard port designated for HTTP (unencrypted web traffic), and Port 443 is the standard port for HTTPS (secure, encrypted web traffic). Allowing both ports enables web clients to connect over standard HTTP as well as secure HTTPS.
