Question
Which of the following open ports should be closed to secure the server properly? (Choose two.)21222353443636
Solution
The question seems to be incomplete as it does not provide the list of open ports to choose from. However, in general, to secure a server properly, you should close all unnecessary open ports. Ports 22 (SSH) and 53 (DNS) are commonly used and may need to be open depending on your server's function, but if they are not in use, they should be closed. Ports 212, 223, 443, and 636 are not commonly used and should be closed unless a specific application requires them.
