Which wireless security protocol replaces the personal pre-shared key (PSK) authentication with Simultaneous Authentication of Equals (SAE) and is therefore resistant to offline dictionary attacks?
The correct answer is C. WPA3-Personal. WPA3-Personal is the wireless security protocol that enhances security by replacing the personal pre-shared key (PSK) authentication with Simultaneous Authentication of Equals (SAE), making it resistant to offline dictionary attacks.

Why each option
WPA3-Personal is the wireless security protocol that enhances security by replacing the personal pre-shared key (PSK) authentication with Simultaneous Authentication of Equals (SAE), making it resistant to offline dictionary attacks.
Bluetooth is a short-range wireless technology for device pairing and data exchange, not a Wi-Fi security protocol that uses PSK or SAE for network authentication.
WPA2-Enterprise uses 802.1X with a RADIUS server for authentication, rather than PSK or SAE, and does not provide the specific SAE-based resistance to offline dictionary attacks on the pre-shared key that WPA3-Personal does.
WPA3-Personal introduces Simultaneous Authentication of Equals (SAE), also known as DragonFly, to establish a secure connection. This handshake mechanism makes it significantly more resilient to offline dictionary attacks compared to the 4-way handshake used in WPA2-Personal, which was vulnerable to such attacks against its PSK.
ZigBee is a low-power, short-range wireless mesh networking standard primarily used for IoT devices and home automation, and it is not a Wi-Fi security protocol that utilizes PSK or SAE for network access.
