CCNA: Cisco Certified Network Associate — Question 1136

How does encryption protect the wireless network?

Answer options

• A. via integrity checks to identify wireless forgery attacks in the frame
• B. via an algorithm to change wireless data so that only the access point and client understand it
• C. via specific ciphers to detect and prevent zero-day network attacks
• D. via a policy to prevent unauthorized users from communicating on the wireless network

Correct answer: B

Explanation

The correct answer is B because encryption transforms data into a format that can only be interpreted by authorized parties, ensuring confidentiality. Option A focuses on integrity checks, which do not provide confidentiality, while C relates to attack detection rather than protection through encryption. Option D addresses user management but does not involve the encryption of data itself.
