Which statement correctly contrasts WPA2-Enterprise and WPA2-Personal?

• A. WPA2-Personal uses a central authentication server (RADIUS) for username/password.
• B. WPA2-Enterprise uses a pre-shared key.
• C. WPA2-Personal relies on 802.1X.
• D. WPA2-Enterprise uses a central authentication server (RADIUS) while WPA2-Personal uses a pre-shared key.

Answer: (D)

The difference hinges on how authentication is handled. WPA2-Enterprise uses a central authentication server (typically a RADIUS server) with 802.1X, meaning each user has individual credentials validated before access is granted and keys are negotiated per session. WPA2-Personal relies on a single pre-shared key configured on both the access point and clients, with no central server or per-user credentials involved.

So the correct distinction is that WPA2-Enterprise uses a central authentication server (RADIUS) while WPA2-Personal uses a pre-shared key. The other statements are off because they describe Personal as using a centralized server, or Enterprise as using a pre-shared key, or Personal relying on 802.1X, which it generally does not.
