CCNA: Cisco Certified Network Associate — Question 910

Which cipher is supported for wireless encryption only with the WPA2 standard?

Answer options

• A. RC4
• B. AES
• C. SHA
• D. AES256

Correct answer: B

Explanation

The correct answer is AES, as it is the encryption standard mandated by WPA2 for secure wireless communications. RC4 is outdated and not recommended for WPA2, while SHA is a hashing algorithm and not used for encryption. AES256 is a variation of AES but is not specifically called out as the standard for WPA2.
