Zorluk: Çok zorMultifunction Devices and Printer Configuration

A network technician is configuring an enterprise multifunction device (MFD) to support remote network printing across different subnets. Workstations on subnet 10.1.10.0/24 can submit jobs to the print server, but the MFD fails to process print jobs transmitted from laptops on subnet 10.1.20.0/24. The technician verifies that network routing is functional and ICMP pings succeed between subnets. Log analysis indicates that standard TCP/IP port printing over RAW (port 9100) is being dropped by the inter-subnet firewall due to a security policy mandating end-to-end transport encryption for print traffic. Which configuration change on the print server and multifunction device will enable encrypted document transmission across subnets while satisfying security compliance?

  1. Configure the print port to use IPPS (Internet Printing Protocol Secure) over TCP Port 631 encrypted with SSL/TLS.Cevap
  2. B
    Reconfigure the printer port on the server to use LPR (Line Printer Remote) over TCP Port 515 with byte counting enabled.
  3. C
    Enable SNMPv3 with authPriv security mode across UDP Ports 161 and 162 on both the server and device.
  4. D
    Change the network print share protocol to SMB3 over TCP Port 445 with required packet signing.

Cevap

Configure the print port to use IPPS (Internet Printing Protocol Secure) over TCP Port 631 encrypted with SSL/TLS.
The correct option identifies IPPS (Internet Printing Protocol Secure), which uses TCP port 631 with SSL/TLS encryption. This protocol allows users to send print jobs securely over network boundaries and through firewalls that require encrypted transport protocols for internal corporate traffic.

Adım Adım Çözüm

1
Identify the cause of dropped print traffic between subnets.
Unencrypted RAW printing on TCP port 9100 is blocked by firewall policies enforcing encryption across subnets.
Firewalls filtering cross-subnet communications drop plain-text print streams when organizational security requirements demand encrypted transport.
2
Evaluate network printing protocols that provide native transport encryption.
IPPS (Internet Printing Protocol Secure) utilizes TCP port 631 wrapped in SSL/TLS.
IPPS satisfies the security requirement by securing document data in transit across router boundaries.
3
Implement the correct printer port configuration on the print server and MFD.
Print jobs are successfully transmitted across subnets over encrypted TCP port 631.
Both client print queues and the MFD EWS must align on IPPS port 631 for secure spooling and printing.
