JNCIA-SEC: Juniper Networks Certified Associate – Security — Question 29

Which method do VPNs use to prevent outside parties from viewing packets in clear text?

Answer options

• A. integrity
• B. authentication
• C. encryption
• D. NAT-T

Correct answer: C

Explanation

The correct answer is C, encryption, as it secures data by converting it into a coded format that can only be read by authorized parties. Options A and B, integrity and authentication, respectively, focus on verifying data accuracy and user identity but do not directly secure the data from being viewed. NAT-T (option D) is a method for facilitating VPN traffic through NAT devices but does not involve protecting the data itself.
