By default, what does the VNC Client and the VNC server daemon use for secure communications?

  1. On SLE 15 the VNC Client assumes the server is set up as a C
  2. Both the VNC Client and the VNC server assume you have access to a valid 3rd party CA like Verisign.
  3. The VNC server prompts the VNC Client for a password that was configured when the VNC server was installed.
  4. VNC is based on the Telnet protocol so encrypted communication between the VNC Client and Server is not possible.
  5. A self-signed SSL certificate

Answer(s): E

Explanation:

By default, the VNC Client and the VNC server daemon use a self-signed SSL certificate for secure communications. The VNC server generates a self-signed certificate when it is started for the first time. The VNC Client will prompt the user to accept or reject the certificate when connecting to the server. Alternatively, the user can provide a custom certificate for the VNC server or disable encryption if desired.
