CCNA: Cisco Certified Network Associate — Question 1240

Which wireless security protocol relies on Perfect Forward Secrecy?

Answer options

• A. WEP
• B. WPA2
• C. WPA
• D. WPA3

Correct answer: D

Explanation

WPA3 is the only protocol among the options that implements Perfect Forward Secrecy, which ensures that session keys are not compromised even if the long-term keys are. WEP and WPA do not provide this level of security, and while WPA2 is an improvement over them, it does not include Perfect Forward Secrecy as a mandatory feature.
