Explanation

B is correct because in the Portal authentication process, after receiving the user's credentials, the Portal server communicates directly with the AAA server to perform authentication - it does not instruct or notify the client to initiate a separate request to the AAA server. The client plays no role in the Portal-to-AAA exchange; that communication happens server-to-server (typically via RADIUS protocol).

Why A is wrong: The statement incorrectly describes the Portal server as delegating AAA communication back to the client. This conflates the client-facing web flow with the backend authentication exchange, which the client never participates in after submitting credentials.

Memory tip: Think of the Portal server as a "middleman bouncer" - the client hands credentials to the bouncer (Portal server), and the bouncer calls headquarters (AAA server) directly to verify. The client never calls headquarters themselves; they just wait for the bouncer's decision.
