Which AAA protocol is used to manage remote and wireless authentication infrastructures?

• A. Extensible Authentication Protocol (EAP)
• B. Remote Authentication Dial-In User Service (RADIUS)
• C. air-gapped
• D. Compute

Answer: (B)

RADIUS is the standard AAA protocol used to manage remote and wireless authentication infrastructures. It acts as a centralized authority for Authentication, Authorization, and Accounting, handling requests from network access devices such as VPN gateways and wireless access points and applying policies before confirming access and logging session data. EAP is a method framework often carried inside RADIUS to perform the actual credential verification (certificates, tokens, passwords), but the overarching protocol that coordinates the process is RADIUS. The other options don’t fit: air-gapped refers to isolated networks, not a protocol, and Compute is not related to authentication protocols.
