How do WPA2/WPA3-PSK and WPA2/WPA3-Enterprise differ in authentication?

• A. PSK uses a unique per-user credential; Enterprise uses a shared password.
• B. PSK uses a shared password; Enterprise uses 802.1X with unique credentials and a RADIUS server.
• C. PSK allows centralized authentication; Enterprise uses a common password.
• D. PSK uses RADIUS; Enterprise does not.

Answer: (B)

Authentication in these WPA modes hinges on how identity is verified. In PSK, every client and the access point share a single password; there’s no centralized user database, so authentication is not per user and depends on the strength and secrecy of that one key. In Enterprise, authentication is done through 802.1X with unique credentials for each user, typically validated by a RADIUS server; this provides per-user authentication, centralized control, and better scalability, and a distinct session key is established for each authenticated user. So, the correct understanding is that PSK uses a shared password, while Enterprise uses 802.1X with unique credentials and a RADIUS server. The other statements mix up who has unique credentials or whether RADIUS is involved, which doesn’t fit how PSK and Enterprise operate.
