Effective CISSP Questions

Wi-Fi Alliance defines a group of wireless networking protocols based on the IEEE 802.11 standards. Wi-Fi Protected Access (WPA) and its successors are common Wi-Fi security protocols. Which of the following is incorrect about Wi-Fi security? (Wentz QOTD)
A. WPA supports both Pre-Shared Key (PSK) and 802.1X authentication
B. WPA2 supports 128-bit AES-CCM encryption and the 4-way handshake in the Personal profile
C. WPA3 supports 192-bit AES-GCM encryption and Dragonfly handshake in the Enterprise profile
D. Wi-Fi 6 follows 802.11ax that boosts in speed and employs WPA3

Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.

My suggested answer is C. WPA3 supports 192-bit AES-GCM encryption and Dragonfly handshake in the Enterprise profile.

Wentz’s book, The Effective CISSP: Security and Risk Management, helps CISSP and CISM aspirants build a solid conceptual security model. It is a tutorial for information security and a supplement to the official study guides for the CISSP and CISM exams and an informative reference for security professionals.

WPA3 supports 192-bit AES-GCM encryption in the Enterprise profile and Simultaneous Authentication of Equals in the Personal profile.
