Describe the authentication differences between WPA2-Enterprise and WPA2-Personal.

• A. Enterprise uses a pre-shared key; Personal uses 802.1X with RADIUS
• B. Enterprise uses WPA2 with TKIP; Personal uses CCMP only
• C. Enterprise uses 802.1X with RADIUS servers; Personal uses a pre-shared key; encryption (AES) is used in both modes.
• D. Enterprise uses no authentication; Personal uses password

Answer: (C)

WPA2-Enterprise and WPA2-Personal mainly differ in how users are authenticated to the network. In WPA2-Enterprise, authentication happens through an 802.1X framework backed by a RADIUS server. This means each user (or device) can have unique credentials and access is granted per user, with the authentication process often using methods like EAP-TLS or PEAP. In WPA2-Personal, authentication relies on a single pre-shared key that is shared among all users; anyone who knows that key can join, so there isn’t per-user authentication or centralized credential management.

Encryption in both modes is AES-based (CCMP) for WPA2, so the main distinction isn’t the encryption but how access is validated. Centralized control and per-user access in Enterprise come from 802.1X with RADIUS, while Personal uses the shared PSK.

That’s why the correct description is that Enterprise uses 802.1X with RADIUS servers, Personal uses a pre-shared key, and AES is used in both modes. The other statements misstate wholaments the authentication method or mix up the roles of the components.
