Final answer:
EAP-TTLS should be recommended for a system that uses both passwords and tokens with TLS. EAP-TLS, EAP-FAST, and EAP-SSL are other options, but EAP-TTLS is more suitable.
Step-by-step explanation:
The recommended EAP for a system that uses both passwords and tokens with TLS is EAP-TTLS. EAP-TTLS (Extensible Authentication Protocol - Tunneled Transport Layer Security) provides a secure communication channel between the client and the authentication server, allowing for the use of different tunneling methods and authentication mechanisms, including passwords and tokens.
EAP-TLS, EAP-FAST, and EAP-SSL are other Extensible Authentication Protocols, but they may not support both passwords and tokens with TLS. EAP-TLS is commonly used with digital certificates, EAP-FAST is often used with Protected Access Credentials (PACs), and EAP-SSL is less commonly used in comparison to EAP-TTLS.
