CCNA: Cisco Certified Network Associate — Question 832

What is a characteristic of encryption in wireless networks?

Answer options

• A. provides increased protection against spyware
• B. prompts a user for a login ID
• C. uses ciphers to detect and prevent zero-day network attacks
• D. prevents the interception of data as it transits a network

Correct answer: D

Explanation

The correct answer, D, is accurate because encryption secures data in transit, making it unreadable to unauthorized parties. Options A and B do not specifically relate to encryption's role in securing wireless communication, while option C incorrectly associates encryption with the detection of network attacks rather than its primary function of securing data.
