A server technician needs to access a remote Unix server for administration. The technician has requested that
ports 23. 25, and 161 be opened on the router. After the ports are opened, the technician is still unable to
connect to the Unix server. Which of the following ports should be opened on the server to allow for remote
administration?
A.
TCP 21
B.
TCP 22
C.
UDP 69
D.
TCP 3389
Hi, the correct answer to this one should be B (tcp 22), because ssh uses port 22 which in this case is needed if Unix system is accessed.

Also RDP (3389) is Microsoft, not UNIX.
