Regarding the role of each role in the Portal authentication architecture, which of the following descriptions is correct? (Multiple choice)

Question

Options

• AThe RADIUS server saves information such as user name and password for authentication of
• BThe Portal server saves information such as user name and password for authentication of access
• CThe RADIUS server is used to push the Portal authentication page to the user
• DThe Portal server is used to push the Portal authentication page to the user

• A
  81% (44)
• B
  7% (4)
• C
  11% (6)

Explanation

In Portal authentication architecture, responsibilities are divided between two distinct servers: the RADIUS server handles credential storage and authentication verification (making A correct), while the Portal server is responsible for delivering the login webpage to unauthenticated users (making D correct).

Option B is wrong because the Portal server does not store usernames or passwords - it only serves the login page UI. It passes submitted credentials upstream to the RADIUS server for actual verification.

Option C is wrong because the RADIUS server has no role in serving web pages - it operates as a backend authentication engine using the RADIUS protocol, not HTTP.

Memory tip: Use the P-P-R-R rule - Portal server = Page delivery; RADIUS server = Records (credentials). If the job involves a webpage, it's Portal; if it involves verifying identity, it's RADIUS.
