CCNA: Cisco Certified Network Associate — Question 690

What are two differences between WPA2 and WPA3 wireless security? (Choose two.)

Answer options

• A. WPA2 uses 192-bit key encryption, and WPA3 requires 256-bit key encryption.
• B. WPA3 uses AES for stronger protection than WPA2, which uses SAE.
• C. WPA2 uses 128-bit key encryption, and WPA3 supports 128-bit and 192-bit key encryption.
• D. WPA3 uses SAE for stronger protection than WPA2, which uses AES.
• E. WPA3 uses AES for stronger protection than WPA2, which uses TKIP.

Correct answer: C, D

Explanation

The correct answers are C and D because WPA2 supports 128-bit key encryption, while WPA3 can use both 128-bit and 192-bit encryption options. Additionally, WPA3 uses the SAE (Simultaneous Authentication of Equals) protocol for improved security, whereas WPA2 relies on AES (Advanced Encryption Standard), which is not accurate in D, as WPA2 does not use AES for authentication.
