Which port range would you configure for VNC to support displays beyond the primary?
Correct Answer:
5900-5907
Explanation:
VNC assigns a port for each display by adding the display number to 5900. The primary display (:0) uses 5900, and additional displays (:1, :2, etc.) map to 5901, 5902, and so on. To support displays beyond the primary, you need the range that covers these ports, which is 5900-5907 (enabling displays 0 through 7). Other port ranges don’t follow VNC’s display-to-port mapping, so they wouldn’t reliably handle extra displays.
