Difficulty: HardMultifunction Devices and Printer Configuration

A system administrator is configuring a newly installed enterprise multifunction device (MFD). Users need to select employee email addresses directly from the corporate Active Directory directory at the device's touch screen interface when using the Scan-to-Email feature, rather than entering addresses manually. The administrator specified the domain controller's IP address on the MFD, but directory searches fail and time out. Network firewalls allow standard traffic between subnets. Which configuration setting on the MFD must the administrator configure to enable dynamic directory lookups?

  1. Enable LDAP settings and specify the bind user account credentials with the target search base DN.Answer
  2. B
    Configure DHCP Option 66 and Option 67 on the MFD network interface to point to the domain controller.
  3. C
    Set up SNMPv3 trap destinations on port 162 to pull automated contacts from the directory server.
  4. D
    Enable Layer 2 LLDP discovery on the embedded web server to automatically sync user accounts.

Answer

Enable LDAP settings and specify the bind user account credentials with the target search base DN.
To enable dynamic directory search on an MFD touch panel, Lightweight Directory Access Protocol (LDAP) must be configured. In addition to specifying the server address, the administrator must configure bind credentials (a domain service account) so the printer can authenticate to Active Directory, along with a search base (Distinguished Name) specifying where in the directory tree to search for users.

Step-by-Step Solution

1
Identify the service requirement for address book auto-lookup on an MFD.
The MFD needs to dynamically query an Active Directory/domain directory for user email addresses.
Active Directory stores directory objects accessible via Lightweight Directory Access Protocol (LDAP).
2
Determine the necessary settings to establish an LDAP connection.
Providing an IP address alone is insufficient; the MFD requires authentication (bind credentials) and a starting point in the directory hierarchy (search base DN).
Active Directory restricts anonymous directory queries by default for security.
3
Evaluate alternative option roles.
DHCP options 66/67 relate to network boot, SNMP relates to status monitoring, and LLDP relates to link layer discovery.
None of these protocols provide directory search capabilities.
