Explanation
IPsec (Internet Protocol Security) is the protocol suite specifically designed to establish authenticated and encrypted channels between two network devices, and it is the foundation of most VPN implementations (e.g., IKEv2/IPsec site-to-site VPNs). It operates at the network layer (Layer 3) and provides confidentiality, integrity, and authentication. PEM (Choice B) is a certificate/key encoding format, not a tunneling protocol. SET (Choice C) is Secure Electronic Transaction, a legacy e-commerce payment protocol. PPP (Choice D) is Point-to-Point Protocol, a basic data-link layer protocol for direct connections that provides no encryption on its own.
