CCNA: Cisco Certified Network Associate — Question 810

What is a characteristic of encryption in wireless networks?

Answer options

• A. identifies an access point on a WLAN
• B. uses the password to connect to an access point
• C. uses integrity checks to identify forgery attacks in the frame
• D. uses authentication protocols to secure a network

Correct answer: C

Explanation

The correct answer is C because encryption in wireless networks often involves integrity checks to ensure that data has not been tampered with, which helps in identifying forgery attacks. Option A relates to identifying access points, which is not about encryption; B mentions connecting with a password, which doesn't directly pertain to encryption; and D discusses authentication, which is a different aspect of network security.
