Explanation

Tunneling creates an encrypted, encapsulated pathway through the public Internet that allows remote users to securely access internal network resources - this is the foundation of how VPNs work, wrapping private traffic inside a protected "tunnel" over an untrusted network.

Spoofing (A) is an attack technique where a malicious actor fakes their identity (IP address, MAC, email sender, etc.) - it's offensive, not a secure access method. Packet sniffing (B) is also an attack/eavesdropping technique used to capture and inspect network traffic, not to establish secure connections. Packet filtering (D) is a firewall mechanism that allows or blocks traffic based on rules - it controls access but does not create a secure connection channel for remote users.

Memory tip: Think of a tunnel under a city - it lets you travel safely through potentially dangerous territory (the public Internet) to reach your destination (internal resources) without being exposed. VPN = tunnel.
