What is the default port a VNC Client uses to connect?
- A. DP 5801
- B. DP 5901
- C. TCP 5901
- D. TCP 5801
Answer: C
Explanation:
Explanation
https://en.wikipedia.org/wiki/Virtual_Network_Computing#:~:text=VNC%20by%20default%20uses%20TCP,Ja VNC by default uses TCP port 5900+N,[6][7] where N is the display number (usually :0 for a physical display). Several implementations also start a basic HTTP server on port 5800+N to provide a VNC viewer as a Java applet, allowing easy connection through any Java-enabled web-browser. Differentport assignments can be used as long as both client and server are configured accordingly. A HTML5 VNC client implementation for modern browsers (no plugins required) exists too.[8] The default port a VNC Client uses to connect is TCP 5901. This port corresponds to the first display number (:1) of the VNC server. Each display number has its own port number, starting from 5900. For example, display :2 uses port 5902, display :3 uses port 5903, and so on. The user can specify a different port number if needed.
