CPSA Port Numbers with Services and Protocols Practice Test

OpenVPN is typically configured to listen on a specific port, and the most common default is 1194, usually using UDP. This port is widely used in OpenVPN setups and appears in standard configurations and documentation, which is why it’s recognized as the default choice. Of course, OpenVPN can run on other ports and can use TCP as well, but 1194 UDP remains the standard and most frequently encountered option. The other numbers are associated with different services (for example, 5432 is PostgreSQL, 6000 is X11), so they aren’t the usual OpenVPN port.
