RADIUS stands for?

• A. Remote Authentication Dial-In User Service
• B. Radiant Access Dial-In User Service
• C. Remote Access Directory and User Service
• D. Remote Authentication Directory for User Services

Answer: (A)

RADIUS is a remote access authentication framework used to centralize authentication, authorization, and accounting for network access. The name itself stands for Remote Authentication Dial-In User Service, which captures its purpose: authenticating users who connect remotely (dial-in or VPN), authorizing their access, and accounting for their session. The other wordings mix up parts of the acronym or replace Dial-In with words that aren’t correct, so they don’t match the established term. This is why the unique, accurate phrase Remote Authentication Dial-In User Service is the right choice.
