Explanation

VPNs are most commonly implemented using IPSec and SSL/TLS. IPSec (Internet Protocol Security) operates at Layer 3 and is widely used for site-to-site and client VPNs, providing authentication and encryption of IP packets. SSL/TLS (used in SSL VPNs) operates at the application layer and is commonly used for remote-access VPNs accessed via a web browser or client (e.g., OpenVPN). SFTP is a file transfer protocol, HTTPS is for web traffic encryption, and SNMP is a network monitoring protocol - none are VPN technologies.
