Port 22 is used for SFTP (Secure File Transfer Protocol) and SCP (Secure Copy Protocol), which encrypt file transfers using SSH (Secure Shell). This ensures data is transmitted securely over the network.
•Why not the other options?
•Port 69 (B) – TFTP (Trivial File Transfer Protocol): Transfers files but is not secure (no encryption).
•Port 80 (C) – HTTP: Used for web traffic, not for file transfer.
•Port 3389 (D) – RDP (Remote Desktop Protocol): Used for remote desktop access, not file transfer.

Question # 58
Which of the following facilities is the best example of a warm site in the event of information system disruption?
A.
A combination of public and private cloud services to restore data
B.
A partial infrastructure, software, and data on site
C.
A full electrical infrastructure in place, but no customer devices on site
D.
A full infrastructure in place, but no current data on site
A warm site typically has a full infrastructure ready, but it lacks the most up-to-date data or is not immediately operational. It requires some configuration or data restoration to become fully functional.
