Answer:
B. LEAP.
Step-by-step explanation:
LEAP is an acronym for Lightweight Extensible Authentication Protocol. It is a Cisco proprietary 802.1X authentication type for Wireless Local Area Networks (WLANs) and an older version of Extensible Authentication Protocol (EAP). LEAP is based on Extensible Authentication Protocol (EAP) and supports a strong mutual handshake or authentication using a logon password between a RADIUS server and the user.
Hence, the security administrator for corp.com should use the LEAP authentication method as it provides dynamic per-user, encryption keys and per-session.
