The correct answer is D. On. Setting Network 1 DHCP RequestTFTPServerAddress to 'On' instructs the endpoint to include a request for DHCP option 150 in its DHCP messages, which provides the TFTP server address used for CUCM provisioning.

Why each option
Setting Network 1 DHCP RequestTFTPServerAddress to 'On' instructs the endpoint to include a request for DHCP option 150 in its DHCP messages, which provides the TFTP server address used for CUCM provisioning.
TFTP is not a valid input value for this setting; the field is a boolean toggle that simply enables or disables the DHCP option 150 request.
150 is the numeric identifier of the DHCP option itself, not an accepted configuration value for this endpoint parameter.
DHCP names the protocol in use but is not a valid entry for the RequestTFTPServerAddress field, which only accepts an on/off state.
Setting this parameter to 'On' enables the endpoint to request DHCP option 150 during the DHCP discovery process. Option 150 carries the TFTP server IP address, which the endpoint uses to download its firmware and configuration file from CUCM, completing the registration process.
