Which port is commonly used by OpenVPN, among these options?

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

Answer: (B)

OpenVPN is typically configured to listen on UDP port 1194, which is the standard default for many installations. This port choice is widely recognized as the default so client and server setups commonly align to it, making it the correct pick among the options. Using UDP helps with faster, more efficient VPN traffic since it has less overhead than TCP, though OpenVPN can be configured to run over TCP or on other ports if needed. The other ports listed are used by different services: 5432 is well known as the PostgreSQL database port, 6000 is associated with the X11 windowing system, and 523 isn’t a standard OpenVPN port. So, the port commonly used by OpenVPN in this set is the default UDP port 1194.
