Which encryption method is used by both WPA2 and WPA3 to provide encryption?

• A. CCMP
• B. RC4
• C. AES
• D. TKIP

Answer: (C)

The main idea is understanding which encryption algorithm remains the same across these Wi‑Fi security standards. AES is the encryption method used by both WPA2 and WPA3 to provide encryption. In WPA2, data is encrypted with AES in CCMP, which delivers both confidentiality and integrity. WPA3 continues with AES-based protection, using AES in an authenticated mode (AES-GCM) for stronger security. The other options don’t fit as the primary encryption algorithm: RC4 is an older, insecure choice that’s not used in WPA2/WPA3; TKIP was a transitional method in WPA2 for compatibility and isn’t the encryption method in WPA3; CCMP refers to the AES-based protocol, not the cipher itself. So the common, underlying algorithm is AES.
