What does port 1194 facilitate?

VPN
SMTP
Telnet
DNS

The correct answer is: VPN

Port 1194 is commonly associated with the OpenVPN protocol, which is used to create secure point-to-point or site-to-site connections in routed or bridged configurations. VPN (Virtual Private Network) technology facilitates secure communications over the internet or other untrusted networks by establishing encrypted tunnels. Therefore, port 1194 is specifically utilized for VPN connections, making it the correct answer in this context. The other options represent different protocols with their own well-known port assignments: SMTP (Simple Mail Transfer Protocol) typically utilizes port 25 for email transmission, Telnet, which is used for plaintext communication over a network, typically uses port 23, and DNS (Domain Name System) generally operates over port 53. These associations highlight why they do not apply to the use of port 1194.
