Difficulty: MediumMultifunction Devices and Printer Configuration

An IT technician is configuring an enterprise multifunction device (MFD) to send scanned financial records directly to a remote storage server using Secure File Transfer Protocol (SFTP). Initial connection tests fail because the MFD is currently set to default unencrypted file transfer settings. Which network port must the technician specify in the MFD scan configuration menu to enable SFTP communications?

  1. Port 22Answer
  2. B
    Port 21
  3. C
    Port 80
  4. D
    Port 443

Answer

Port 22 is required for SFTP communications on the multifunction device.
Secure File Transfer Protocol (SFTP) runs over Secure Shell (SSH), which uses TCP port 22 by default. When configuring an MFD to scan directly to an SFTP server, the destination port must be set to 22 to establish an encrypted tunnel for authentication and document transmission.

Step-by-Step Solution

1
Identify the required network protocol for the MFD scan-to-file destination
The destination server requires Secure File Transfer Protocol (SFTP).
SFTP relies on Secure Shell (SSH) for transport layer security.
2
Determine the standard TCP port associated with SSH/SFTP
TCP port 22 is the standard port for SSH and SFTP connections.
Standard FTP uses port 21, whereas SFTP routes all traffic encrypted over port 22.
3
Update the MFD scanner destination profile settings
The MFD successfully negotiates an encrypted session over port 22 and delivers scan files.
Matching the MFD protocol port settings with the target server firewall and service configuration resolves connection failures.
