Which technology creates an encrypted tunnel to securely connect to the enterprise network from a remote location?

• A. Remote Access
• B. Secure Shell (SSH)
• C. Virtual Private Network (VPN)
• D. Network Access Control (NAC)

Answer: (C)

A secure remote connection to the enterprise network is achieved by creating a private, encrypted path over a public network so all traffic between the remote user and the internal resources is protected. This is what a VPN does: it tunnels your data through an encrypted channel, letting you access internal systems as if you were on the corporate network, while keeping eavesdropping and tampering at bay.

Remote access is a broad term for connecting from afar, but the mechanism that guarantees the secure tunnel is the VPN. SSH provides an encrypted link primarily for secure remote command-line access or for tunneling specific services, not for general network access to the whole enterprise. NAC focuses on evaluating and enforcing device security before or during access, rather than creating an encrypted tunnel for remote connectivity. So the encrypted tunnel that securely connects to the enterprise network from a remote location is provided by a VPN.
