Difficulty: Very hardMultifunction Devices and Printer Configuration

A network technician is deploying a corporate Multifunction Device (MFD) to support secure Scan-to-Email using authenticated SMTP over TLS with a cloud-based email provider. In what logical sequence should the technician perform the following steps to complete the configuration?

  1. 1Verify TCP/IP network settings and specify valid internal DNS server addresses on the MFD.
  2. 2Import the email provider's Root CA certificate into the MFD's trusted certificate store.
  3. 3Configure the remote SMTP server FQDN, set the submission port to 587, and enable STARTTLS encryption.
  4. 4Enter the dedicated service account login credentials for SMTP user authentication.
  5. 5Execute a test scan-to-email transaction from the MFD control panel to verify message delivery.

Answer

The correct order of steps is: 1) Verify TCP/IP network settings and specify valid internal DNS server addresses on the MFD; 2) Import the email provider's Root CA certificate into the MFD's trusted certificate store; 3) Configure the remote SMTP server FQDN, set the submission port to 587, and enable STARTTLS encryption; 4) Enter the dedicated service account login credentials for SMTP user authentication; 5) Execute a test scan-to-email transaction from the MFD control panel to verify message delivery.
The configuration follows a standard system dependency hierarchy: basic IP and DNS name resolution must be established first, followed by cryptographically trusting the remote server (Root CA), setting up encrypted protocol endpoints (SMTP port 587 with STARTTLS), applying user authentication credentials, and finally performing functional validation.

Step-by-Step Solution

1
Ensure IP addressing and DNS server configuration on the MFD.
The device achieves network layer reachability and can resolve external hostnames.
Without name resolution, the MFD cannot establish communication with domain-based cloud SMTP servers.
2
Install the public Root CA certificate on the MFD via EWS.
The device establishes trust for the mail provider's SSL/TLS certificates.
TLS connections fail security negotiation if the issuing CA is not present in the device's trust store.
3
Define SMTP server address, submission port 587, and STARTTLS protocol.
The MFD establishes the transport layer parameters for outbound email.
Configuring port 587 with STARTTLS establishes encrypted communication prior to credential transmission.
4
Input service account username and password for SMTP authentication.
The MFD authenticates successfully with the cloud mail relay.
Credentials must be passed over the securely established STARTTLS connection.
5
Initiate a test scan from the device control panel.
End-to-end confirmation of scan processing, authentication, and mail routing.
Validation verifies that all network, security, and credential layers function seamlessly.
