QuestionQ90

Infrastructure Services

An engineer configured a DHCP server so Cisco IP phones could download their configuration from a TFTP server, but the IP phones did not load the configuration.

What must be configured to fix the issue?

  • A BOOTP port 67
  • B DHCP option 66
  • C BOOTP port 68
  • D DHCP option 69
Explanation

DHCP option 66 provides Cisco IP phones with the hostname or IP address of a TFTP server, enabling them to locate and download their configuration. BOOTP ports 67 and 68 carry DHCP traffic but do not supply the TFTP server location, and port 69 is the TFTP transport port.
