Why each option
EAP (Extensible Authentication Protocol) is the authentication framework used in 802.1X-based wireless networks and point-to-point connections.
EAP is a flexible authentication framework defined in RFC 3748 that encapsulates various authentication methods (EAP-TLS, PEAP, EAP-FAST, etc.) and operates at Layer 2. It is the foundation of 802.1X port-based authentication used in Wi-Fi WPA2/WPA3-Enterprise deployments and PPP-based point-to-point links, making it the correct answer for both use cases mentioned.
L2TP (Layer 2 Tunneling Protocol) is a tunneling protocol for VPNs and does not define an authentication framework.
TKIP (Temporal Key Integrity Protocol) is a deprecated encryption and integrity mechanism for WPA, not an authentication framework.
PPP (Point-to-Point Protocol) is a Layer 2 data-link protocol that can carry authentication sub-protocols like EAP, but PPP itself is not the authentication framework.
Concept tested: EAP as 802.1X authentication framework
