220-1102 Question #325: Real Exam Question with Answer & Explanation

Question

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?

Options

• ADNS
• BIPS
• CVPN
• DSSH

Explanation

A Virtual Private Network (VPN) creates a secure, encrypted tunnel over an insecure network, effectively hiding IP addresses and securing all encapsulated network traffic.

Common mistakes.

• A. DNS (Domain Name System) is a protocol for translating domain names to IP addresses; it does not secure network traffic or hide IP addresses directly.
• B. IPS (Intrusion Prevention System) is a security device or software that monitors network traffic for malicious activity and can block it, but it does not create a secure tunnel or hide IP addresses.
• D. SSH (Secure Shell) creates an encrypted connection for remote login and command execution, and can be used for secure tunneling of specific applications, but a VPN is designed to secure all network traffic from a device, hiding its IP broadly.
