RADIUS is primarily used as what kind of system?

• A. An authentication and accounting system
• B. A data encryption standard
• C. A web hosting protocol
• D. A file transfer method

Answer: (A)

RADIUS is used to manage network access by performing authentication, authorization, and accounting for users who want to connect to a network. It acts as a central AAA server that a network access server consults to verify identity, determine what resources the user is allowed to access, and log session details for auditing and billing. That focus on verifying who you are, what you’re allowed to do, and recording your activity is why the best description is an authentication and accounting system. It isn’t a data encryption standard, which would specify how to encrypt data; it isn’t a web hosting protocol, which handles delivering web content; and it isn’t a file transfer method, which governs moving files between systems.
