CompTIA A+ Core 2 (220-1102) — Question 223

A technician is creating a tunnel that hides IP addresses and secures all network traffic. Which of the following protocols is capable of enduring enhanced security?

Answer options

• A. DNS
• B. IPS
• C. VPN
• D. SSH

Correct answer: C

Explanation

The correct answer is VPN, as it is designed specifically to create secure connections over the internet by encrypting data and masking IP addresses. While DNS, IPS, and SSH provide various levels of security, they do not offer the same comprehensive protection for all network traffic as a VPN does.
