Which port is commonly used by OpenVPN, among the options listed?

• A. 523
• B. 1194
• C. 6000
• D. 5432

Answer: (B)

OpenVPN’s default behavior uses UDP on port 1194 because UDP offers lower overhead and faster tunnel setup, which suits VPN traffic well. This default port is widely documented and commonly used, making it the go-to choice for a standard OpenVPN setup. You can run OpenVPN over TCP or on a different port if you configure it that way, but 1194 UDP is the conventional and most recognized option. The other ports listed don’t align with typical OpenVPN usage: 6000 is associated with the X11 windowing system, 5432 with PostgreSQL, and 523 isn’t a standard VPN port. That’s why 1194 stands out as the common OpenVPN port.
