Jane, a security administrator, needs to implement a secure wireless authentication method that uses a remote RADIUS server for authentication. Which of the following is an authentication method Jane

The correct answer is D. LEAP. LEAP (Lightweight Extensible Authentication Protocol) is a Cisco-developed EAP method that authenticates users against a remote RADIUS server, making it the correct choice here. WPA2-PSK (Pre-Shared Key) and WEP-PSK use a shared password distributed to all users - no RADIUS serve

Explanation

LEAP (Lightweight Extensible Authentication Protocol) is a Cisco-developed EAP method that authenticates users against a remote RADIUS server, making it the correct choice here. WPA2-PSK (Pre-Shared Key) and WEP-PSK use a shared password distributed to all users - no RADIUS server is involved. CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) is an encryption protocol used in WPA2, not an authentication method. LEAP, as part of the 802.1X/EAP framework, passes credentials to a RADIUS server for centralized authentication. Note: LEAP is considered weak due to known vulnerabilities and has largely been replaced by EAP-TLS or PEAP in production, but it remains a test-relevant answer for RADIUS-based wireless authentication.
