Which non-standard port is commonly used for HTTPS alternatives?

• A. 443 TCP
• B. 8443 TCP
• C. 9443 TCP
• D. 8080 TCP

Answer: (B)

When you run secure web traffic, HTTPS normally uses a fixed port (port 443). In many setups, administrators put HTTPS on a non-standard port to distinguish management interfaces or separate services from public web traffic. Among widely used non-standard options, 8443 has become the go-to choice for HTTPS-enabled applications and admin consoles. It’s the default HTTPS port for several application servers (like Tomcat) and is commonly seen in devices and services that expose a secure interface on a non-443 port. That’s why this port is recognized as a common HTTPS alternative.

The other ports aren’t as representative for HTTPS: 443 is the standard HTTPS port, not non-standard; 8080 is typically used for HTTP alternatives; and 9443 exists in some products but isn’t as broadly adopted as a default non-standard HTTPS port.
