OpenVPN is used to provide encrypted tunneling for VPNs. Which of the following options reflects this role?

• A. Stunnel
• B. OpenVPN
• C. VeraCrypt
• D. OpenSSH

Answer: (B)

Encrypted tunneling for VPNs means creating a secure channel over a public network to carry private network traffic. OpenVPN does exactly that: it establishes a VPN tunnel between client and server, encapsulating traffic inside an encrypted, TLS-secured channel and routing it through a virtual network interface. It supports flexible configurations, including UDP or TCP transport, and uses certificates or keys for authentication, ensuring confidentiality and integrity of data in transit. The other tools have different primary roles—Stunnel adds TLS encryption as a wrapper for existing protocols but isn’t a full VPN solution by itself; VeraCrypt is for disk encryption (data at rest); OpenSSH provides secure remote access and can forward ports, but it isn’t a dedicated VPN solution. So OpenVPN best reflects the role of providing encrypted tunneling for VPNs.
