CCNA: Cisco Certified Network Associate — Question 1168

Which mechanism allows WPA3 to provide a higher degree of security than its predecessors?

Answer options

• A. automatic device pairing
• B. SAE password-based key exchange
• C. certificate-based authentication
• D. special-character support in preshared keys

Correct answer: B

Explanation

The correct option, B, SAE password-based key exchange, improves security by using a more robust method for exchanging keys securely, making it resistant to offline dictionary attacks. The other options, while relevant to security, do not directly contribute to the fundamental improvements in key exchange mechanisms that WPA3 introduces.
