A municipal operations center needs every staff AP to check user credentials against a central AAA store before granting WLAN access. Which authentication service belongs in that design?
Select an answer to reveal the explanation.
Short Explanation
Think of RADIUS as the city’s badge desk for Wi-Fi. The AP doesn’t keep every employee password in its pocket—it asks a central AAA server. Shared PSKs, MAC lists, and click-to-accept portals aren’t that central credential check.
Full Explanation
Enterprise WLAN designs that require centralized credential validation use RADIUS as the AAA service that APs or controllers query during 802.1X authentication. Local PSKs, open SSIDs with MAC filters, and simple captive-portal acknowledgments do not provide that AAA function. Selecting RADIUS aligns the municipal WLAN with scalable, policy-driven enterprise authentication.
