312-50V9 Question #93: Real Exam Question with Answer & Explanation
The correct answer is A: Extensible Authentication Protocol (EAP). EAP is the protocol used by smart card authentication systems to securely convey certificate credentials during the authentication handshake.
Question
Smart cards use which protocol to transfer the certificate in a secure manner?
Options
- AExtensible Authentication Protocol (EAP)
- BPoint to Point Protocol (PPP)
- CPoint to Point Tunneling Protocol (PPTP)
- DLayer 2 Tunneling Protocol (L2TP)
Explanation
EAP is the protocol used by smart card authentication systems to securely convey certificate credentials during the authentication handshake.
Common mistakes.
- B. PPP is a data link layer encapsulation protocol for serial connections and does not itself provide a mechanism for transferring or validating certificates.
- C. PPTP is a VPN tunneling protocol that encapsulates PPP frames for transmission over IP networks but does not define a certificate transfer mechanism.
- D. L2TP is a tunneling protocol that creates a virtual point-to-point connection but relies on IPsec for security and does not handle certificate exchange independently.
Concept tested. EAP certificate-based smart card authentication
