• DHTTPS protocol

• D

Explanation

EAP (Extensible Authentication Protocol) is not part of Portal authentication - it belongs to the 802.1X authentication framework, which operates at Layer 2 and is used for wired/wireless network access control via RADIUS. Portal authentication is a web-based, Layer 3 mechanism that relies on redirecting unauthenticated users to a login page.

• B (HTTP) is wrong because HTTP is the foundational transport used to redirect users to the portal login page and carry authentication requests.
• C (Portal protocol) is wrong because the Portal protocol is the dedicated communication protocol between the access device (NAS) and the Portal server, handling authentication status exchange - it's a core component.
• D (HTTPS) is wrong because HTTPS is commonly used to secure the portal login page and protect credential submission.

Memory tip: Think of Portal authentication as a web-based system - anything web-related (HTTP, HTTPS, Portal protocol) belongs. EAP is for 802.1X, which is a completely different authentication family; if you see "EAP," think Wi-Fi enterprise / RADIUS, not portals.
